Guide 15,Retrieval and Analysis of Soluble Salts
You are purchasing a downloadable pdf of this Standard.
This Guide describes the most commonly used field methods for the retrieval and analysis of soluble salts on steel and other nonporous substrates. Laboratory methods are only included for situations where laboratory control is desired.
Coatings applied on surfaces contaminated with soluble salts exceeding a certain concentration exhibit diminished performance. This Guide is intended to assist the user in selecting specific procedures for retrieving and analyzing soluble salts. It discusses the various methods for retrieving salts from a surface and the analytical methods used to determine the concentration of the soluble salts in the extracted solution. Appendices include information on sources of testing equipment and materials.
