ASTM A153 和A123 都是镀锌的标准，有什么区别呢？
例如，管道和弯头镀锌时，如何选用这两个标准？

A153的应用范围：This specification covers zinc coatings applied by the
hot-dip process on iron and steel hardware
A123的应用范围：This specification covers the requirements for zinc
coating (galvanizing) by the hot-dip process on iron and steel
products made from rolled pressed and forged shapes, castings,
plates, bars, and strips.
应该说A123的应用规定要严格许多。对镀层的厚度，平均厚度等都有较严格的规定。
当然度管件的要用A123了。
