ASTM B545 2013 Edition, “Standard Specification for Electrodeposited Coatings of Tin,” has just been released. It is the first revision of the document since 1997. It is one of the basic plating specifications used by our customers, and a frequently order document as well.
ASTM B545 – 13 covers the requirements for electrodeposited coatings of tin used on metallic articles. Tin coatings create a low contact-resistance surface which means the articles are protected against corrosion. Tin coatings also facilitate soldering, provide anti-galling properties, and are a stopoff coating in the nitriding of high-strength steels.
Changes can be found in the following sections:
- 4.3.3, Flow-Brightened Electrodeposits
- 5.1.8
- 6.6, Adhesion
- 6.7.1, Gross Defects/Mechanical Damage
- 6.10, Deposit Purity
- Appendix X2, Adhesion Tests
- Appendix X3, Solderability Tests
- Appendix X4, Some Definitions of Wetting Terminology
- Appendix X5, Sulfur Dioxide Porosity Test (Steel Substrates)
- Appendix X6, Design Considerations
