The sampling plan used for the b4888 of the quality of the coated articles shall be as agreed upon between the purchaser and the supplier.
ASTM B – 18 Standard Specification for Electrodeposited Coatings of Gold for Engineering Uses
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. Government and Military, including as subcontracts, shall be packaged in accordance with Practice D It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Therefore, the coating thickness at v488 single point on the signi? Iron, nickel and cobalt combined shall be less than 0. Accurate Precision Plating APP is a leading metal finishing services company, specializing in high quality, precision gold plating services for industrial applications.

Go to Navigation Go to Content. 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. Any bath that produces v488 meeting the requirements of the speci? In a closed polyethylene bottle, the equilibrated water will remain in the range from 0. Special racks may involve the use of conforming, auxiliary, bipolar electrodes, or nonconducting shields.
The size of the sample and the criteria of compliance are determined by the application of statistics.
Acid pickling of high strength steels shall be avoided. 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? This is particularly useful in automatic reel-to-reel applications in which dwell times are atm All non-gold metals, excluding potassium and sodium, are considered impurities and shall not be present in amounts greater than 0.
Deposit hardness should be determined on samples at plating conditions representative of actual production. Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM B to measure the thickness of the coating. Values provided in parentheses are for information only. Such acceptance or pass-fail criteria, if required, shall be part of the product speci? Any such defects on signi?
Government or an agent of the U. Some typical uses of gold coatings are enumerated below, but the list is not complete and is intended for general guidance only. Oxidation of co-deposited metals can make soldering more difficult.
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. Cracking without separation does not indicate poor adhesion unless the coating can be peeled back with a sharp instrument.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Work Item s – proposed revisions of this standard. Several types of coatings, differing in gold purity and hardness, are covered by this speci?

We offer our clients a superior product due to our attention to detail and commitment to quality, supported by the highest level of customer service. NOTE 7—In certain instances in aztm high-frequency analog signals are employed, such as in wave guides, the magnetic properties of nickel may attenuate the signal.
A suggested water extract conductivity test method uses a procedure in accordance with Test Methods D, Method A. Coatings with purities of Once it has been established that the co-deposited b4488 impurity limitations are being continuously met in production, frequency of determination can be reduced.
