Organization: ASTM
Publication Date: 1 December 2015
Status: active
Page Count: 3
ICS Code (Surface preparation): 25.220.10
scope:

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

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

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.

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

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
