SCOPE This specification defines the performance requirements for the instrument cluster assembly and visible components behind and including the lens. 2. APPLICATION This specification was r
3、eleased originally for instrument clusters. Testing must be conducted on parts per Table 1, which defines sample size and testing required. Chrome components outside of the lens must meet WSS-M1P83-E1/Latest. Painted components outside of the lens must meet WSS-M2P188-B1/Latest Foil / Film covered s
4、urfaces outside of the lens must meet WSS-M15P34-E/Latest Graphic printing outside of the lens must meet WSS-M2P158-A1/Latest Molded-in-color plastic components outside of the lens must meet WSS-M15P4-G/Latest 2.1 LIMITATIONS HALS (Hindered Amine Light Stabilizers) is prohibited in PC/ABS resins. HA
5、LS UV stabilizer degrades the polymer in the presence of moisture causing cracking/crazing of the resin. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification is performance based and does not have approved sources. 3.2 SYSTEM COMPONENTS 3.2.1 Resistance to Scratch Initial Hardness of all painted
6、parts within this assembly must be cured/dry at time of packing to withstand normal handling and shipping without marring. 3.2.2 Substrate ABS, Polycarbonate, Polypropylene or as specified on Engineering Drawing. Substrate must not contain any additives, or mold release agents which will adversely a
7、ffect the in mold decorating process. 3.2.3 Aging Test panels or test specimens prepared for investigations according to this specification must be aged for at least 72 h at 23 +/- 2 C or 16 h at 45 +/- 1 C prior to testing.
