Annotation of standard text ASTM B840-22 :

This specification covers the requirements for electrodeposited zinc cobalt alloy coatings on metals. The coating class is Class 1 and five coating types are Type a, Type b, Type c, Type d, and Type e. The metal to be plated shall be subjected to such cleaning, pickling, and electroplating procedures. Coating requirements include: substrate, nature of coating, appearance, thickness, adhesion, corrosion resistance, and pre- and post-coating treatments of iron and steel for reducing the risk of hydrogen embrittlement. Adhesion, porosity, corrosion resistance, or appearance tests shall be made.
