 The ADISA Product Claims and Product Assurance Schemes are different levels of product testing for data sanitization tools.·        The Product Claims Test (PCT) scientifically evaluates the claim behind the data sanitization capabilities of a software or hardware device to determine its validity.·        The Product Assurance Test offers a higher level of assurance than the PCT; it requires a larger sample size to be forensically analysed and measures the vendors of the software or hardware device against a range of requirements.
