1.1 This test method covers (1) the determination of mass gain, and (2) the surface inspection of products of zirconium, hafnium, and their alloys when corrosion tested in water at 680°F or in steam at 750°F.
1.2 This test method is to be utilized in its entirety to the extent specified herein as a product acceptance test.
1.3 This test method may be used on wrought products, castings, powder metallurgy products, and weld metals.
1.4 A complete metric companion to this test method has been developed, Test Method G 2M. Therefore, no metric equivalents are shown. However, since the mass gain and surface area of the specimen and the electrical resistivity of water are always measured or calculated in SI units, these are given in SI units.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 9.
