ASTM B695-21

Die Annotation des Normtextes ASTM B695-21 :

This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. The thickest coating classes are usually referred to as ""mechanically galvanized"". All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement. All tests results should comply with the given requirements.
