scope:

This procedure shall be followed to allow for a part manufacturer's ongoing control of appearance quality for production parts. Appearance quality pertains to aesthetic properties, specifically color and gloss for this document, to ensure harmony coordination (for interior trim components) as originally approved by the Appearance Approval Report (AAR). The concept of quality control (QC) for aesthetic properties is relevant to exterior trim as well as interior trim. This specification's primary focus is for low gloss interior trim. This procedure defines the instrumental measurement criteria and documentation, as well as a procedure for working standards, required for a supplier of appearance parts to control appearance aesthetic quality.

The following functional areas support this procedure:

• GM Design Quality

• Supplier of the production part

• GM Supplier Quality groups

GM continues to specify color and gloss via a visual match to the appropriate master (such as the Primary Color Master, Primary Gloss Master, or Production Part Approval Process (PPAP) Master), as documented on the Color and Trim Design Appearance Release (CTDAR), Design Appearance Release (DAR), or Appearance Requirements Drawing (ARD) referenced in the part math data file (or drawing). Visual evaluation remains the primary requirement for match-to requirements into GM.

Visual requirements are used to ensure color harmony across various parts manufactured from different materials and processes where part differences may negatively affect instrument performance.

Mission/Theme. This procedure is supplemental information to the Pre-texture, Post-texture, and Part Appearance Approval Report (AAR) procedures specified in the PPAP manual published by the AIAG (Automotive Industry Action Group). These techniques are set forth to ensure vehicle aesthetic appearance harmony through Statistical Process Control (SPC) of appearance attributes.

Classification. This procedure is relevant to all parts with color and gloss match-to requirements.
