Permission rights to photocopy the standard may also be secured from the ASTM website www. When plated parts are used in mating applications, the maximum thickness shall not exceed the tolerance speci?
Your comments are invited either atm revision of this awtm or for additional standards and should be addressed to ASTM International Headquarters. All other metals, excluding potassium and nitrogen, shall be considered impurities and shall not be present in amounts greater than 0.
NOTE 14—The test to be selected will depend upon the gold thickness, the nature of the basis metal, the nature and thickness of any intermediate layers or underplate, the shape of the gold-coated part, and its intended service environment.
However, the use of these undercoatings requires the approval of the purchaser. NOTE 8—In applications in which forming or? Benefits of Gold Plating Electrical Components Gold is the ultimate precious metal for electrical contact plating.
Thickness of the underplating should be consistent with end-use requirements. They must be smooth and as free of scratches, gouges, nicks, and similar imperfections as possible. Thus, the appearance of test coupons may serve as an indication of an approaching need for the activated carbon treatment.
For Type I Code B and C coatings, metallic hardening agents such as nickel, cobalt or iron combined shall be equal to or less than 0. Test Method B contains four sampling plans, three for use with tests that are nondestructive and one with those that are destructive. Government or an agent of the U.
It is customary that allowance for plated coatings be included within the part tolerance. This contamination can have the effect of producing discoloration of the deposit. Cracking without separation does not indicate poor adhesion unless the coating can be peeled back with a sharp instrument.

In addition, the average coating thickness on articles will vary from article to article within a production lot. Such acceptance or pass-fail criteria, if required, shall be part of the product speci? No separation of the coating from the substrate shall occur.
Special racks may involve the use of conforming, auxiliary, bipolar electrodes, or nonconducting shields. B — 11 Standard Speci? V488 to Navigation Go to Content. Selection of the type and thickness of the gold coating is determined by the desired life in the operating environment of the electroplated component.
For that reason, the electrodeposition of gold is used extensively in electrical component applications such as electrical contacts, connector pins, switches, sensors and many others for which repeated physical contact occurs. Values provided in parentheses are for information only.
