GMW15195 2nd Edition, June 1, 2013 Documentation for Control of Appearance Aesthetic Quality; Color and Gloss
More info
Description / Abstract:
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.
