Last previous edition approved in as B — 01 e This specification does not cover gold coatings produced from autocatalytic, immersion, and vapor deposition. A minimum of 0.
Test Method B contains four sampling plans, three for use with tests that are nondestructive and one with those that are destructive.
It is informational asgm and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Values provided in parentheses are for information only. Properly performed, this process will ensure coated products of satisfactory quality and will reduce the amount of acceptance inspection. Cracking without separation does not indicate poor adhesion unless the coating can be peeled back with a sharp instrument.
The sampling plan used for the inspection of the quality of the astk articles shall be as agreed upon between the purchaser and the supplier. It is the responsibility of the user of this standard axtm establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

It is soluble in water and forms carbonic acid that ionizes and is at equilibrium at 0. Government or an agent astn the U. Nonmagnetic Coatings on Magnetic Basis Metals.
ASTM B – 18 Standard Specification for Electrodeposited Coatings of Gold for Engineering Uses
However, care must be taken to ensure that the thickness of the Type I or Type II gold topcoat is sufficient so as not to compromise wear properties. The thickness of the underplating should be consistent with end-use requirements see 6. Can be the source of corrosion products or tarnish? A number in parentheses indicates the year of last reapproval. Government and Military, including as subcontracts, shall be packaged in accordance with Practice D The location of rack or wire marks in the coating shall be agreed upon between the purchaser and the supplier.

ASTM B488 Gold Plating Standard
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Call today to see how we can solve your plating challenges. The conductivity of the water extract is measured, and the increase in conductivity due to residual salts and other conducting impurities is calculated.
Coatings shall be sampled, tested and conform to specified requirements as to purity, hardness, appearance, thickness, mass per unit area, ductility, adhesion assessed by either bend, heat, or cutting testand integrity including gross defects, mechanical damage, and porosity.
All other metals, excluding potassium and nitrogen, shall be considered impurities and shall not be present in amounts greater than 0. The size of the sample and the criteria of compliance are determined by the application of statistics.
Oxidation of co-deposited metals can make soldering more difficult. You can be assured b488 gold plating project will be completed right the first time and your part delivered to you production-ready. For some applications this requirement may be relaxed to allow for a small number of such defects per unit areaespecially if they are outside or on the periphery of the signi?

A suggested four-point method is detailed in Test Method F NOTE 8—In applications in which forming or? Aastm is the ultimate precious metal for electrical contact plating. See Guide B for guidelines for selecting the appropriate test method.
