2、 Belt Hardware; Corrosion Resistance I 1.0 APPLICATION This specification applies to the steel hardware contained in seat belt assemblies, normally designated as either attachment hardware (at or near the floor) or other hardware such as buckles, retractors, tongues, and similar metallic parts. 2.0
3、SCOPE This specification covers only the finish requirements; mechanical, chemical, and physical property requirements and test methods are defined by applicable Federal, State, and SAE specifications. 3.0 REFERENCE DOCUMENTS Unless otherwise specified, the latest issue of all referenced standards s
4、hall apply. The following standards, specifications and regulations are referenced in this specification. Quality System Standard QS-9000 (IS0 9001) FMVSS - 209 INTERNATIONAL IQR Quality Standard INTERNATIONAL Manufacturing Standard D-13 ASTM B 287 ASTM B 456 CFR Title 29, Part 1910 4.0 GENERAL REOU
5、IREMENTS Parts and assemblies supplied to this specification must meet all applicable requirements of Federal Motor Vehicle Safety Standard No. 209 (FMVSS-209). 4.1 Plating; Requirements Hardware shall be either zinc, or nickel chromium plated steel or fabricated from a stainless steel with a minimu
6、m of 11.5% chromium content. 4.1.1 Finish: Parts may be supplied with either a bright, semi-bright, dull, or satin finish. The specific finish to be used on a given part or assembly will be determined by TDTC Body Group and specified on the Engineering drawing. 4.2 Post Plating; Treatment All electr
7、oplated parts shall be free from hydrogen embrittlement. A typical treatment is to bake (within two hours after plating) for four hours at 190-205C (375-400F). Mechanically plated parts do not require a baking treatment. 4.2.1 Passivation: Stainless steel parts shall be passivated by immersion in a
8、dilute nitric acid solution after manufacture. 4.2.2 Conversion Treatment: Zinc plating shall be followed by a clear chromate conversion treatment on arts that will be visible after installation in a vehicle.
