ASTM G122-96(2008)

The purpose of this test method is to define a procedure for evaluating the capability of cleaning agents to clean metallic coupons. Based on the outcome of the testing, suitable cleaning agents may be selected for cleaning in general and for oxygen service in particular.

The cleaning parameters can be changed and the test method can be repeated. The usual cleaning parameters include cleaning agent concentration, temperature, and time; type and strength of ultrasonic energy or agitation, if used, and others.

Note 1—Usual cleaning parameters are based on the manufacturer's recommendations.

1.1 This test method covers a procedure for evaluating the capability of cleaning agents and processes to remove contamination to the desired level.

1.2 The test coupons provide a relatively rough surface to which contamination can easily adhere.

1.3 The capability of a particular cleaning agent depends upon the method by which it is used and the characteristics of the article being cleaned, such as size, shape, and material. Final evaluation of the cleaning agent should include testing of actual products and production process.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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. Specific precautionary statements are given in Note 2.
