Standard Test Method for Conductimetric Analysis of Water Soluble Ionic Contamination of Blast Cleaning Abrasives

Importancia y uso:

4.1 Abrasive media may contain ionic contamination naturally (for example, mineral abrasives), from manufacturing (quenching with contaminated water), transportation, storage or use (in the case of abrasive that is reused). Ionic contamination on the abrasive may transfer to the surface during abrasive blast cleaning, resulting in potential osmotic blistering, accelerated underfilm corrosion and premature coating failure.

4.2 This test method describes a shop/field procedure for assessing the level of conductive species on an abrasive.

4.3 Abrasive standards published by AMPP (AB) and ISO 11126 provide tolerance levels for water soluble contaminants of the abrasive.
