Note: In th
2、e event of conflict between the English and domestic language, the English language shall take precedence. 1.1 Scope. This document establishes the requirements for the Interior Decorative Trim (IDT) used in General Motors (GM) vehicles. All requirements in this standard apply to each unique decorat
3、ive trim component, design and interface. The required functions, performance, appearance, design constraints, and validation of the components are defined by this document. 1.1.1 Certain sections or paragraphs are broad in scope as this document must cover many different constructions, design conce
4、pts, and trim levels to meet the needs of the full range of GM vehicles. Therefore, program specific requirements that may not be covered within this specification are identified in the Statement of Requirements (SOR) Appendix C2. 1.2 Mission/Theme. The primary purpose of the IDT is to provide an at
5、tractive appearance within the vehicles interior while at the same time offering components that comply with subsystem and vehicle level requirements. 1.3 Classification. The IDT is typically classified as an injection molded substrate that may be decorated with paint, film, chrome and/or genuine ma
6、terials such as wood, aluminum or carbon fiber. This specification does not include components that are mold in color, solely painted for gloss control or wrapped in a textile or leather. 2 References Note: Only the latest approved standards are applicable unless otherwise specified. 2.1 External St
