    S6 Test conditions and procedures.
    S6.1 Dynamic systems test for child restraint systems.
    The test conditions described in S6.1.1 apply to the dynamic
systems test. The test procedure for the dynamic systems test is
specified in S6.1.2. The test dummy specified in S7 is placed in the
test specimen (child restraint system), clothed as described in S9 and
positioned according to S10.
    S6.1.1 Test conditions--(a) Test devices. (1) Add-on child
restraint systems. The test device for add-on child restraint systems
is a standard seat assembly consisting of a simulated vehicle rear seat
which is depicted in NHTSA Standard Seat Assembly; FMVSS No. 213, No.
NHTSA-213-2021 (March 2023) (incorporated by reference; see Sec.
571.5). The assembly is mounted on a dynamic test platform so that the
center SORL of the seat is parallel to the direction of the test
platform travel and so that movement between the base of the assembly
and the platform is prevented. As illustrated in Figures 1A and 1B of
this standard, attached to the seat belt anchorage points provided on
the standard seat assembly is a Type 1 or a Type 2 seat belt assembly.
The seat belt assembly meets the requirements of Standard No. 209
(Sec.  571.209) and has webbing with a width of not more than 2 inches,
and are attached to the anchorage points without the use of retractors
or reels of any kind. As illustrated in Figures 1A' and 1B' of this
standard, attached to the standard seat assembly is a child restraint
anchorage system conforming to the specifications of Standard No. 225
(Sec.  571.225). The indentation force deflection (IFD) characteristics
of the seat pan cushion and seat back cushion are described in drawing
numbers 3021-233 and 3021-248 in the NHTSA Standard Seat Assembly;
FMVSS No. 213, No. NHTSA-213-2021, (March 2023) (incorporated by
reference; see Sec.  571.5); the IFD is measured on the full size
cushion samples using the test methodology and apparatus described in
ASTM Standard D3574-11 (incorporated by reference; see Sec.  571.5) at
50% indentation.
    (2) The test device for built-in child restraint systems is either
the specific vehicle shell or the specific vehicle.
    (i) Specific vehicle shell. (A) The specific vehicle shell, if
selected for testing, is mounted on a dynamic test platform so that the
longitudinal center line of the shell is parallel to the direction of
the test platform travel and so that movement between the base of the
shell and the platform is prevented. Adjustable seats are in the
adjustment position midway between the forwardmost and rearmost
positions, and if separately adjustable in a vertical direction, are at
the lowest position. If an adjustment position does not exist midway
between the forwardmost and rearmost position, the closest adjustment
position to the rear of the midpoint is used. Adjustable seat backs are
in the manufacturer's nominal design riding position. If such a
position is not specified, the seat back is positioned so that the
longitudinal center line of the child test dummy's neck is vertical,
and if an instrumented test dummy is used, the accelerometer surfaces
in the dummy's head and thorax, as positioned in the vehicle, are
horizontal. If the vehicle seat is equipped with adjustable head
restraints, each is adjusted to its highest adjustment position.
    (B) The platform is instrumented with an accelerometer and data
processing system having a frequency response of 60 Hz channel
frequency class as

specified in SAE Recommended Practice J211/1, (incorporated by
reference, see Sec.  571.5). The accelerometer sensitive axis is
parallel to the direction of test platform travel.
    (ii) Specific vehicle. For built-in child restraint systems, an
alternate test device is the specific vehicle into which the built-in
system is fabricated. The following test conditions apply to this
alternate test device.
    (A) The vehicle is loaded to its unloaded vehicle weight plus its
rated cargo and luggage capacity weight, secured in the luggage area,
plus the appropriate child test dummy and, at the vehicle
manufacturer's option, an anthropomorphic test dummy which conforms to
the requirements of subpart B or subpart E of part 572 of this title
for a 50th percentile adult male dummy placed in the front outboard
seating position. If the built-in child restraint system is installed
at one of the seating positions otherwise requiring the placement of a
part 572 test dummy, then in the frontal barrier crash specified in
paragraph (c) of this section, the appropriate child test dummy shall
be substituted for the part 572 adult dummy, but only at that seating
position. The fuel tank is filled to any level from 90 to 95 percent of
capacity.
    (B) Adjustable seats are in the adjustment position midway between
the forward-most and rearmost positions, and if separately adjustable
in a vehicle direction, are at the lowest position. If an adjustment
position does not exist midway between the forward-most and rearmost
positions, the closest adjustment position to the rear of the midpoint
is used.
    (C) Adjustable seat backs are in the manufacturer's nominal design
riding position. If a nominal position is not specified, the seat back
is positioned so that the longitudinal center line of the child test
dummy's neck is vertical, and if an anthropomorphic test dummy is used,
the accelerometer surfaces in the test dummy's head and thorax, as
positioned in the vehicle, are horizontal. If the vehicle is equipped
with adjustable head restraints, each is adjusted to its highest
adjustment position.
    (D) Movable vehicle windows and vents are, at the manufacturer's
option, placed in the fully closed position.
    (E) Convertibles and open-body type vehicles have the top, if any,
in place in the closed passenger compartment configuration.
    (F) Doors are fully closed and latched but not locked.
    (G) All instrumentation and data reduction are in conformance with
SAE Recommended Practice J211/1, (incorporated by reference, see Sec.
571.5).
    (b) The tests are frontal barrier impact simulations of the test
platform or frontal barrier crashes of the specific vehicles as
specified in S5.1 of Sec.  571.208 and for:
    (1) Test Configuration I, are at a velocity change of 48 km/h with
the acceleration of the test platform entirely within the curve shown
in Figure 2, or for the specific vehicle test with the deceleration
produced in a 48 km/h frontal barrier crash.
    (2) Test Configuration II, are set at a velocity change of 32 km/h
with the acceleration of the test platform entirely within the curve
shown in Figure 3, or for the specific vehicle test, with the
deceleration produced in a 32 km/h frontal barrier crash.
    (c) As illustrated in Figures 1A and 1B of this standard, attached
to the seat belt anchorage points provided on the standard seat
assembly are Type 1 or Type 2 seat belt assemblies. These seat belt
assemblies meet the requirements of Standard No. 209 (Sec.  571.209)
and have webbing with a width of not more than 2 inches, and are
attached to the anchorage points without the use of retractors or reels
of any kind. As illustrated in Figures 1A' and 1B' of this standard,
attached to the standard seat assembly is a child restraint anchorage
system conforming to the specifications of Standard No. 225 (Sec.
571.225).
    (d)(1) When using the test dummy specified in 49 CFR part 572,
subparts I and K, performance tests under S6.1 are conducted at any
ambient temperature from 19 [deg]C to 26 [deg]C and at any relative
humidity from 10 percent to 70 percent.
    (2) When using the test dummies specified in 49 CFR part 572,
subpart N, P, R or T, performance tests under S6.1 are conducted at any
ambient temperature from 20.6 [deg]C to 22.2 [deg]C and at any relative
humidity from 10 percent to 70 percent.
    (e) In the case of add-on child restraint systems, the restraint
shall meet the requirements of S5 at each of its seat back angle
adjustment positions and restraint belt routing positions, when the
restraint is oriented in the direction recommended by the manufacturer
(e.g., forward, rearward or laterally) pursuant to S5.6, and tested
with the test dummy specified in S7.

child restraint system to any tension of not less than 9 Newtons and
not more than 18 Newtons on the webbing at the top of each dummy
shoulder and the pelvic region.
    (e) Accelerate the test platform to simulate frontal impact in
accordance with Test Configuration I or II, as appropriate.
    (f) Determine conformance with the requirements in S5.1.
    S6.2 Buckle release test procedure. The belt assembly buckles used
in any child restraint system shall be tested in accordance with S6.2.1
through S6.2.4 inclusive.
    S6.2.1 Before conducting the testing specified in S6.1, place the
loaded buckle on a hard, flat, horizontal surface. Each belt end of the
buckle shall be pre-loaded in the following manner. The anchor end of
the buckle shall be loaded with a 9 N force in the direction away from
the buckle. In the case of buckles designed to secure a single latch
plate, the belt latch plate end of the buckle shall be pre-loaded with
a 9 N force in the direction away from the buckle. In the case of
buckles designed to secure two or more latch plates, the belt latch
plate ends of the buckle shall be loaded equally so that the total load
is 9 N, in the direction away from the buckle. For pushbutton-release
buckles, the release force shall be applied by a conical surface (cone
angle not exceeding 90 degrees). For pushbutton-release mechanisms with
a fixed edge (referred to in Figure 7 as ``hinged button''), the
release force shall be applied at the centerline of the button, 3 mm
away from the movable edge directly opposite the fixed edge, and in the
direction that produces maximum releasing effect. For pushbutton-
release mechanisms with no fixed edge (referred to in Figure 7 as
``floating button''), the release force shall be applied at the center
of the release mechanism in the direction that produces the maximum
releasing effect. For all other buckle release mechanisms, the force
shall be applied on the centerline of the buckle lever or finger tab in
the direction that produces the maximum releasing effect. Measure the
force required to release the buckle. Figure 7 illustrates the loading
for the different buckles and the point where the release force should
be applied, and Figure 8 illustrates the conical surface used to apply
the release force to pushbutton-release buckles.
    S6.2.2 After completion of the testing specified in S6.1 and before
the buckle is unlatched, tie a self-adjusting sling to each wrist and
ankle of the test dummy in the manner illustrated in Figure 4, without
disturbing the belted dummy and the child restraint system.
    S6.2.3 Pull the sling tied to the dummy restrained in the child
restraint system and apply the following force: 50 N for a system
tested with a newborn dummy (49 CFR part 572, subpart K); 90 N for a
system tested with a 12-month-old dummy (49 CFR part 572, subpart R);
200 N for a system tested with a 3-year-old dummy (49 CFR part 572,
subpart P); 270 N for a system tested with a 6-year-old dummy (49 CFR
part 572, subpart N or I); 350 N for a system tested with a weighted 6-
year-old dummy (49 CFR part 572, subpart S); or 437 N for a system
tested with a 10-year-old dummy (49 CFR part 572, subpart T). The force
is applied in the manner illustrated in Figure 4 and as follows:
    (a) Add-on child restraint systems. For an add-on child restraint
system other than a car bed, apply the specified force by pulling the
sling horizontally and parallel to the SORL of the standard seat
assembly. For a car bed, apply the force by pulling the sling
vertically.

    (b) Built-in child restraint systems. For a built-in child
restraint systems other than a car bed, apply the force by pulling the
sling parallel to the longitudinal centerline of the specific vehicle
shell or the specific vehicle. In the case of a car bed, apply the
force by pulling the sling vertically.
    S6.2.4 While applying the force specified in S6.2.3, and using the
device shown in Figure 8 for pushbutton-release buckles, apply the
release force in the manner and location specified in S6.2.1, for that
type of buckle. Measure the force required to release the buckle.

    (a) [Reserved]
    (b) When testing rear-facing child restraint systems, place the
newborn, or 12-month-old dummy in the child restraint system so that
the back of the dummy torso contacts the back support surface of the
system. For a child restraint system which is equipped with a fixed or
movable surface described in S<IP_ADDRESS> which is being tested under the
conditions of test configuration II, do not attach any of the child
restraint system belts unless they are an integral part of the fixed or
movable surface. For all other child restraint systems and for a child
restraint system with a fixed or movable surface which is being tested
under the conditions of test configuration I, attach all appropriate
child restraint system belts and tighten them as specified in S6.1.2.
Attach all appropriate vehicle belts and tighten them as specified in
S6.1.2. Position each movable surface in accordance with the
instructions that the manufacturer provided under S5.6.1 or S5.6.2. If
the dummy's head does not remain in the proper position, tape it
against the front of the seat back surface of the system by means of a
single thickness of 6 mm-wide paper masking tape placed across the
center of the dummy's face.
    (c) When testing rear-facing child restraint systems, extend the
dummy's arms vertically upwards and then rotate each arm downward
toward the dummy's lower body until the arm contacts a surface of the
child restraint system or the standard seat assembly in the case of an
add-on child restraint system, or the specific vehicle shell or the
specific vehicle, in the case of a built-in child restraint system.
Ensure that no arm is restrained from movement in other than the
downward direction, by any part of the system or the belts used to
anchor the system to the standard seat assembly, the specific shell, or
the specific vehicle.
    S10.2.2 Other dummies generally. When using: (1) the Hybrid III 3-
year-old (part 572, subpart P), and Hybrid III weighted 6-year-old
(part 572, subpart S) in child restraint systems including belt-
positioning seats; (2) the Hybrid III 6-year-old (part 572, subpart N)
and the Hybrid III 10-year-old (part 572, subpart

T) in child restraint systems other than belt-positioning seats,
position the dummy in accordance with S5.6.1 or S5.6.2, while
conforming to the following:
    (a) Holding the test dummy torso upright until it contacts the
system's design seating surface, place the test dummy in the seated
position within the system with the midsagittal plane of the test dummy
head--
    (1) Coincident with the center SORL of the standard seating
assembly, in the case of the add-on child restraint system, or
    (2) Vertical and parallel to the longitudinal center line of the
specific vehicle, in the case of a built-in child restraint system.
    (b) Extend the arms of the test dummy as far as possible in the
upward vertical direction. Extend the legs of the dummy as far as
possible in the forward horizontal direction, with the dummy feet
perpendicular to the center line of the lower legs.
    (c) Using a flat square surface with an area of 2580 square
millimeters, apply a force of 178 N, perpendicular to:
    (1) The plane of the back of the standard seat assembly, in the
case of an add-on system, or
    (2) The back of the vehicle seat in the specific vehicle shell or
the specific vehicle, in the case of a built-in system, first against
the dummy crotch and then at the dummy thorax in the midsagittal plane
of the dummy. For a child restraint system with a fixed or movable
surface described in S<IP_ADDRESS>, which is being tested under the
conditions of test configuration II, do not attach any of the child
restraint system belts unless they are an integral part of the fixed or
movable surface. For all other child restraint systems and for a child
restraint system with a fixed or movable surface which is being tested
under the conditions of test configuration I, attach all appropriate
child restraint system belts and tighten them as specified in S6.1.2.
Attach all appropriate vehicle belts and tighten them as specified in
S6.1.2. Position each movable surface in accordance with the
instructions that the manufacturer provided under S5.6.1 or S5.6.2.
    (d) After the steps specified in paragraph (c) of this section,
rotate each dummy limb downwards in the plane parallel to the dummy's
midsagittal plane until the limb contacts a surface of the child
restraint system or the standard seat assembly, in the case of an add-
on system, or the specific vehicle shell or specific vehicle, in the
case of a built-in system, as appropriate. Position the limbs, if
necessary, so that limb placement does not inhibit torso or head
movement in tests conducted under S6.
    (e) Additional provisions when using the Hybrid III 3-year-old
(part 572, subpart P) dummy in a rear-facing child restraint system.
    (1) When using the Hybrid III 3-year-old dummy in a rear-facing
child restraint system with an internal harness or other components to
restrain the child, remove the knee stop screw (as shown in drawing
210-6516 of Drawing No. 210-5000-1 (L),-2(R), Leg Assembly in subpart P
of part 572 of this chapter (incorporated by reference, see Sec.
571.5) from the right and left knee so as to let the knees hyperextend.
    (2) Place the subpart P dummy in the child restraint system being
tested so that the back of the dummy torso contacts the back support
surface of the system. For a child restraint system equipped with a
fixed or movable surface described in S<IP_ADDRESS> that is being tested
under the conditions of test configuration II, do not attach any of the
child restraint system belts unless they are an integral part of the
fixed or movable surface. For all other child restraint systems and for
a child restraint system with a fixed or movable surface that is being
tested under the conditions of test configuration I, attach all
appropriate child restraint system belts and tighten them as specified
in S6.1.2. Attach all appropriate vehicle belts and tighten them as
specified in S6.1.2. Position each movable surface in accordance with
the instructions that the manufacturer provided under S5.6.1 or S5.6.2.
    S10.2.3 Hybrid III 6-year-old in belt-positioning seats, Hybrid III
weighted 6-year-old in belt-positioning seats, and Hybrid III 10-year-
old in belt-positioning seats. When using the Hybrid III 6-year-old
(part 572, subpart N), the Hybrid III weighted 6-year-old (part 572,
subpart S), or the Hybrid III 10-year-old (part 572, subpart T) in
belt-positioning seats, position the dummy in accordance with S5.6.1 or
S5.6.2, while conforming to the following:
    (a) Prepare the dummy. (1) When using the Hybrid III 10-year-old
dummy, prepare the dummy according to the following:
    (i) Set the dummy's neck angle at the SP-16 setting (``SP'' means
standard procedure), see Figure 14a.
    (ii) Set the dummy's lumbar angle at the SP-12 setting, see Figure
14b. This is done by aligning the notch on the lumbar adjustment
bracket with the SP-12 notch on the lumbar attachment.
    (iii) Adjust the limb joints to 1-2 g while the torso is in the
seated position.
    (iv) Apply double-sided tape to the surface of a lap shield, which
is a piece of translucent silicone rubber 3 mm 0.5 mm thick
(50A durometer) cut to the dimensions specified in Figure 13 in this
section. Place the lap shield on the pelvis of the dummy. Align the top
of the lap shield with the superior anterior edge of the pelvis skin.
Attach the lap shield to the dummy.
    (v) Apply double-sided tape to one side of a pelvis positioning
pad, which is a 125 x 95 x 20 mm (2 mm tolerance in each of
the three dimensions) piece of closed cell (Type 2 according to ASTM
D1056-07) (incorporated by reference; see Sec.  571.5) foam or rubber
cut from material having the following specifications: compression
resistance between 9 to 17 psi in a compression-deflection test
specified in ASTM D1056-07 (incorporated by reference; see Sec.
571.5), and a density of 7 to 12.5 lb/ft\3\. Center the long axis of
the pad on the posterior of the pelvis with the top edge of the foam
aligned with the superior edge of the pelvis skin. Attach the pelvis
positioning pad to the dummy.
    (vi) Dress and prepare the dummy according to S9.
    (2) When using the Hybrid III 6-year-old dummy and the Hybrid III
weighted 6-year-old dummy, prepare the dummy according to the
following:
    (i) If necessary, adjust the limb joints to 1-2 g while the torso
is in the seated position.
    (ii) Apply double-sided tape to the surface of a lap shield, which
is a piece of translucent silicone rubber 3 mm thick 0.5 mm
thick (50A durometer) cut to the dimensions specified in Figure 13.
Place the lap shield on the pelvis of the dummy. Align the top of the
lap shield with the superior anterior edge of the pelvis skin. Attach
the lap shield to the dummy.
    (iii) Dress and prepare the dummy according to S9.
    (b) Position the belt-positioning seat. Position the belt-
positioning seat according to S6.1.2(a)(1)(ii).
    (c) Position the dummy. Position the dummy in the belt-positioning
seat.
    (1) Place the dummy on the seat cushion of the belt-positioning
seat such that the plane of the posterior pelvis is parallel to the
plane of the seat back of the belt-positioning seat, standard seat
assembly or vehicle seat back, but not touching. Pick up and move the
dummy rearward, maintaining the parallel planes, until the pelvis
positioning pad, if used, or the pelvis or back of the dummy and the
back of the belt-positioning seat or the back of the standard seat
assembly, are in minimal contact.
    (2) Straighten and align the arm segments horizontally, then rotate
the

arms upward at the shoulder as far as possible without contacting the
belt-positioning seat. Straighten and align the legs horizontally and
extend the lower legs as far as possible in the forward horizontal
direction, with the feet perpendicular to the centerline of the lower
legs.
    (3) Using a flat square surface with an area of 2580 square
millimeters, apply a force of 178 N (40 lb) first against the dummy
crotch and then against the dummy thorax on the midsagittal plane of
the dummy, perpendicular to:
    (i) The plane of the back of the belt-positioning seat, in the case
of a belt-positioning seat with a back, or,
    (ii) The plane of the back of the standard seat assembly or vehicle
seat, in the case of a backless belt-positioning seat or built-in
booster.
    (4) Rotate the arms of the dummy down so that they are
perpendicular to the torso.
    (5) Bend the knees until the back of the lower legs are in minimal
contact with the belt-positioning seat, standard seat assembly or
vehicle seat. Position the legs such that the outer edges of the knees
are 180 10 mm apart for the Hybrid III 6-year-old dummy and
220 10 mm apart for the Hybrid III 10-year-old dummy.
Position the feet such that the soles are perpendicular to the
centerline of the lower legs. In the case of a belt-positioning seat
with a back, adjust the dummy so that the shoulders are parallel to a
line connecting the shoulder belt guides. This can be accomplished by
leaning the torso such that the dummy's head and neck are centered on
the backrest components of the belt-positioning seat. In case of a
backless child restraint system, adjust the dummy's torso so that the
head is as close to laterally level as possible.
    (d) Apply the belt. Attach the vehicle belts and tighten them as
specified in S6.1.2.
    (e) Dummy final positioning. (1) Check the leg, feet, thorax and
head positions and make any necessary adjustments to achieve the
positions described in S10.2.3(c)(5). Position the legs, if necessary,
so that the leg placement does not inhibit thorax movement in tests
conducted under S6.
    (2) Rotate each dummy arm downwards in the plane parallel to the
dummy's midsagittal plane until the arm contacts a surface of the child
restraint system or the standard seat assembly, in the case of an add-
on system, or the specific vehicle shell or specific vehicle, in the
case of a built-in system, as appropriate. Position the arms, if
necessary, so that the arm placement does not inhibit torso or head
movement in tests conducted under S6.
