4、e Notice: NEW Reference: Keywords: Treated wood, ACQ, 1.0 APPLICATION This specification covers the requirements for a corrosion resistant, duplex coating system which combines an electroplated zinc and chromate substrate with an organic topcoat. This coating system must be free of hexavalent chromi

5、um. This finish is intended for use on ferrous fasteners and small parts used in contact with treated wood, such as ACQ (alkaline copper quaternary) and other commercially available wood treatments. 2.0 SCOPE This specification covers the general coating requirements, part performance, quality, KCC,

6、 source approval and quality control, packing, shipping, and identification requirements, and designation on drawings. 2.1 Restricted Chemical Substances Effective January 1, 2007, all product supplied to the requirements of this specification must comply with the requirements of the CEMS B-50 speci

7、fication. 3.0 REFERENCE DOCUMENTS Unless otherwise specified, the latest issue of all referenced standards shall apply.

The maximum thickness on threads is limited by the basic thread size and tolerances. After coating, the parts must pass t

12、he appropriate thread GO gages without sticking or binding. 4.2 Part Performance 4.2.1 Adhesion Coated parts shall be tested for 100 hours min in 100% RH at 38C (100F), after 72 hours min aging at room temperature. After testing, parts shall show no evidence of blistering, flaking, peeling, or appea

13、rance changes. 4.2.2 Durability/Flexibility For coated fasteners, samples must be able to survive 10 installation cycles in and out of treated wood without substantial coating loss. Coating shall withstand normal handling and storage conditions without flaking, chipping, or loss of adhesion. 4.2.3 C

14、orrosion Resistance Coated parts will be exposed to neutral salt spray testing per ASTM B 117 for 1000 hr. Externally threaded fasteners will first be power driven into treated wood before testing. After testing, samples will show no base metal corrosion. 5.0 QUALIFICATION Pre-production samples, ac

15、companied by a certified laboratory report, indicating conformance to all requirements of this specification, shall be submitted to Truck Development and Technology Center for testing and approval prior to shipment of production parts. 5.1 KCC - Quality Control Plan A Quality Control Plan for this p
