February 29, 2008
what are the standard recommended tests for hot dip galvanized
material as per ASTM 123

Adhesion is rarely an issue with hot dip galvanizing, but if you
find a standard referring to it, it should also tell you how it can
be measured or refer to another standard that does.
Because the mechanism of coating is alloying, not just a coating
sticking to the steel, it either has happened or not. Rarely does the
alloy form but be not adhered.

Adhesion as Mr.Geoff said should not be a major problem, but still
some inspectors inist on that, according to astm
A123 [link is to spec at TechStreet], take a stout
knife and with considerable pressure take forward movement if the
coating is intact your adhesion shall be good enough.
