This PAS describes a method for assessing the performance of the forensic code as used in a forensic marking product over time and through exposure to artificial weathering simulating both internal and external environments.<\/p>\n

\n

NOTE 1<\/i><\/b> Forensic codes in forensic marking systems can be used, for example, in the identification of the legitimate ownership of an item; for confirmation that an item is genuine (anti-counterfeiting) and to link a suspect with the scene of a crime.<\/i><\/p>\n<\/blockquote>\n

It also specifies requirements for manufacture, record keeping, labelling of the forensic code and the uniqueness of the forensic code.<\/p>\n

It is applicable to forensic codes that require laboratory analysis to verify their unique code.<\/p>\n

It also specifies a classification system based on performance under artificial weathering conditions, which comprises the following classification codes:<\/p>\n

    \n
  1. Grade A (external);<\/li>\n
  2. Grade A (internal);<\/li>\n
  3. Grade B (external);<\/li>\n
  4. Grade B (internal);<\/li>\n
  5. Grade C (external);<\/li>\n
  6. Grade C (internal).<\/li>\n<\/ol>\n
    \n

    NOTE 2<\/i><\/b> Grade A represents the longest functional test life and Grade C the shortest.<\/i><\/p>\n<\/blockquote>\n

    This PAS does not cover:<\/p>\n

      \n
    1. forensic codes, or forensic marking products, where the forensic code cannot be verified using laboratory analysis;<\/li>\n
    2. the performance of the forensic code within a forensic marking product in resisting removal from a surface, whether deliberate or accidental;\n

      NOTE 1<\/i><\/b> This does not include the effects of artificial weathering.<\/i><\/p>\n

      NOTE 2<\/i><\/b> This property is determined by the composition of the forensic marking product and the surface to which it is applied.<\/i><\/p>\n<\/li>\n

    3. the performance of covert and overt markers that might be components of forensic marking products;<\/li>\n
    4. the requirements for other components of a forensic marking product (e.g. polymers, adhesives, dyes, solvents, greases, fluorescent or phosphorescent pigments, anti-fungicides);<\/li>\n
    5. requirements for forensic marking products, i.e. the product in\/on which the forensic code is used;<\/li>\n
    6. forensic codes intended to have a functional test life of less than 6 months.<\/li>\n<\/ol>\n
      \n

      NOTE 3<\/i><\/b> Testing a forensic code in isolation is not usually possible. Testing is undertaken on a forensic code within a representative forensic marking product. The results might not be applicable for the same forensic code as used in different forensic marking products.<\/i><\/p>\n<\/blockquote>\n
