This specification is for the performance of labels, affixed to parts or components within or enroute to GM facilities. Labels under this specification may have temporary or permanent applications for assembly verification and/or traceability. Labels identified under this specification shall be classified as Types I, II, III, or IV. Type I, II, and III shall be computer imprintable labels which may or may not be bar coded.

Material Descriptions

Type I. These type labels are temporary computer imprintable labels, for parts applied at tire suppliers. These will typically be made of a #60 paper stock and have no further function after the labeled part is installed on the vehicle. These labels shall only contain a surface print. For these type labels the print shall not be adversely affected by 24 h exposure to 100% RH at 33°C, nor by handling the printed surface with gloved or ungloved hands.

Type II These type labels are permanent. Computer imprintable parts identification labels, for interior applications, applied at tier suppliers. These labels shall consist of a polyester film, with a matte coating, surface printed.

Type III These type labels are permanent. Computer imprintable labels for underhood or other harsh environments. These labels shall consist of a polyester film, surface printed, with a polyester laminate.

Type IV. These type labels are for permanent applications for underhood or other harsh environments. These labels will consist of a polyester film with a subsurface print.
