GM4350M - Painted Part Performance Requirements

Scope:
This standard covers laboratory test requirements for a number of classes of paint finishes commonly used for automobile components. This standard does not cover appearance requirements or processing parameters (exception: see Section 3.1.1) which are expected to be specified in material specifications (998XXXX) and is not intended to cover paint finishes as used in connection with vacuum deposited metal coatings and hot stamped coatings. For painted plastic parts only, the combinations of substrate, surface preparation and applied paints shall be used that are shown in GM Approved Paint on Parts Systems (APOPS) database. When APOPS testing is performed each test must be completed on a minimum of 3 samples, each obtained from separate parts. Parts which are source primed and subsequently top-coated at assembly plants shall be capable of accepting the specified topcoat paint system and meet all the test requirements of this standard.
