ASTM G 47 Document Information:
Title
Standard Test Method for Determining Susceptibility to Stress-Corrosion Cracking of 2XXX and 7XXX Aluminum Alloy Products
ASTM International
Publication Date:
Apr 10, 1998
Scope:
This test method covers a uniform procedure for characterizing the
resistance to stress-corrosion
cracking (SCC) of high-strength aluminum alloy wrought products for
the guidance of those who
perform stress-corrosion tests, for those who prepare stress-corrosion
specifications, and for
materials engineers.
This test method covers method of sampling, type of specimen, specimen
preparation, test
environment, and method of exposure for determining the susceptibility
to SCC of 2XXX (with 1.8 to
7.0 % copper) and 7XXX (with 0.4 to 2.8 % copper) aluminum alloy
products, particularly when
stressed in the short-transverse direction relative to the grain
structure.
The values stated in SI units are to be regarded as standard. The
inch-pound units in parentheses
are provided for information.
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.
