SCOPE These specifications define the performance requirements for a paint or powder coat system with adequate appearance and durability for metal parts in exterior low or non visible areas
4、 WSK-M2P152-A1 For parts requiring light corrosion resistance, or functional requirements. WSK-M2P152-A2 For parts requiring moderate corrosion resistance, or functional requirements. WSK-M2P152-A3 For parts requiring severe corrosion resistance, or long-time functional requirements. WSK-M2P152-A4
5、For parts requiring extra severe corrosion resistance, or extra long-time functional requirements. 2. APPLICATION These specifications were released originally to provide adequate corrosion resistance for exterior low level visible parts. Four levels provide flexibility of application and are specif
6、ied depending on use, position and exposure resistance required. 3. REQUIREMENTS 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as described therein is required for material/source approval. Appropriate sta
7、tistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.2 CONDITIONING All parts shall be aged for 72 h at 23 +/- 2 C or 16 h at 43 +/- 2 C before testing for resistance properties unless otherwise specified. 3.3 SYSTEM COMPONENTS
