This document specifies:

a)       the determination of mass gain;

b)       the surface inspection of products of hafnium when corrosion tested in water at 360 °C.

This document is applicable to hot-work or cold-work hafnium rods, wires, plates, sheets and strips.

This method has been widely used in the development of hafnium products. It is applicable for use in its entirety to the extent specified for a product acceptance test, rather than merely a means of assessing performance in service of pressurized water reactor.
