Title
Standard Test Method for Coulometric Reduction of Surface Films on Metallic Test Samples
ASTM International
Publication Date:
Oct 10, 2002
Scope:
This test method covers procedures and equipment for determining
the relative buildup of corrosion and tarnish films (including
oxides) on metal surfaces by the constant-current coulometric
technique, also known as the cathodic reduction method.
This test method is designed primarily to determine the relative
quantities of tarnish films on control coupons that result from
gaseous environmental tests, particularly when the latter are used
for testing components or systems containing electrical
contacts.
This test method may also be used to evaluate test samples that
have been exposed to indoor industrial locations or other specific
application environments. (See 4.6 for limitations.)
This test method has been demonstrated to be applicable
particularly to copper and silver test samples (see
(1)).2 Other metals require further study to prove their
applicability within the scope of this test method.
The values stated in SI units are the preferred units. The
values provided in parentheses are for information only.
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 become familiar with all hazards
including those identified in the appropriate Material Safety Data
Sheet (MSDS) for this product/material as provided by the
manufacturer, to establish appropriate safety and health practices,
and determine the applicability of regulatory limitations prior to
use.
