SCOPE The materials defined by these spe
3、cifications are polycarbonate resins characterized by high strength and high heat resistance. These materials are naturally transparent. Three types are defined. 2. APPLICATION ESF-M4D100-A1: This specification was released originally for material used in applications requiring optical clarity, such
4、 as instrument cluster light filters and lenses. This material may be color pigmented when optical transparency is not required, and may be specified for applications requiring high strength and high impact resistance. This general purpose resin is not used for exterior signal lenses. ESB-M4D100-A2:
5、 This specification was released originally for material used in exterior signal lamp lenses incorporating reflex reflectance where any surface change due to weathering is unacceptable (SAE J 576c). These applications, when using material defined by this specification, must have an approved coating
6、(para 3.4.5) applied to the first surface. ESB-M4D100-A3: This specification was released originally for material used in uncoated exterior signal lamp lenses not incorporating reflex reflectance. Note: Materials defined by ESF-M4D100-A1 or ESB-M4D100-A2 designation correspond to former ESF-M4D100-A
7、, Type I or Type II designation as follows: ESF-M4D100-A1 replaces ESF-M4D100-A, Type I ESB-M4D100-A2 replaces ESF-M4D100-A, Type II Existing drawings specifying ESF-M4D100-A, Type I or Type II, do not require revision to reflect this new classification. ESF-M4D100-A specification shown without type
8、 designation is understood to be ESF-M4D100-A1. ESF-M4D100-A1 also replaces ESB-M4D100-A1. Drawings showing the ESB-M4D100-A1 do not require revision to reflect the ESF designation. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform
9、to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 MOLDED TEST SPECIMEN The following requirements are intended for initial source qualifications, and Initial Sample Inspection Report. These will be rechecked at intervals specified by Quality Assurance. ENGINEERING
