This standard does not purport to address the safety concerns, if any, associated with its use. Coatings shall be classified into types according to minimum purity, grade according to surface appearance bright, semibright, or matand class according to whether any surface treatment has been applied. Plating Specifications Download 7b00. When a nickel undercoat is not used on copper and copper alloy materials or when a copper undercoat is used on other materials, then the silver ashm service should not be used for continuous service at a temperature in excess of degrees Fahrenheit.
Silver Plating Standards – ASTM B & QQ-SC | Accurate Precision Plating
Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM to measure the thickness of the coating. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Medical Device Silver Plating.

Some of these applications include:. Tarnish Resistance To increase the tarnish resistance of the silver plating, supplementary coatings such as a painting or powder coating can be recommended depending on subsequent finishing steps and solderability. Nickel undercoats should be applied for silver plating on copper and copper alloys. The adhesions of the silver plating can be adversely affected due to a weak copper and silver inter-metallic v700.
As it is not a rare, naturally occurring metal, silver oxidizes quickly but out of all the metals, its the one that is the most electrically and thermally conductive. This specification establishes the requirements for electrodeposited silver coatings that may be mat, bright, or semibright, and are usually employed as solderable surfaces and for their electrical contact characteristics, high electrical and thermal conductivity, thermocompression bonding, wear resistance on load-bearing surfaces, and spectral reflectivity.

Coatings shall undergo preplating operations such as stress relief treatment, strike, and underplating, as well as post-plating embrittlement relief. Coatings shall be sampled, tested, and conform accordingly to specified requirements as to nature, purity, appearance, defects, adhesion, solderability, hardness, adtm reflectance, electrical conductivity, hydrogen embrittlement relief, and thickness measured either zstm by beta backscatter, X-ray spectrometry, or magnetic method, or destructively by coulometric technique or microscopical cross-sectioning procedure.

Corrosion Protection A nickel undercoat with silver plating wstm be used for applications where corrosion protection is important. Silver plating is a highly electric conductive and has outstanding properties for contacts and connectors.
