Organization: ASTM International
Publication Date: 1 December 2015
Status: inactive
Page Count: 3
ICS Code (Surface preparation): 25.220.10
significance And Use:

4.1 Abrasive media may contain ionic contamination naturally (for example, beach sand), from manufacturing (quenching with contaminated water), transportation, storage or use (in the case of... View More

scope:

1.1 This test method describes a procedure for assessing blast cleaning abrasives for the presence of conductive-potential, ionic contaminants by determining the total concentration of water soluble conductive species using a conductivity test.

1.2 This test method does not identify the ionic species present nor provide quantitative results on each species.

1.3 This test method is based on a volume comparison among abrasives of similar sizes. A volume comparison is more closely related to surface area of the abrasives than is a weight comparison.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
