42 MATERIALS PERFORMANCE October 2010 NACE International, Vol. 49, No. 10 Measuring Surface Salts : conductivity vs. Ion specific TestingH. Peters, CHLOR*RID International, Inc., Chandler, ArizonaTesting and identifying residual Surface Salts is an integral part of proper Surface preparation; their removal is pivotal to the long-term performance of industrial coatings. Consequential risk reduction translates to lower life-cycle costs. Two commercial field methods are discussed to provide the user guidance on the method most suited to identifying the presence of Salts where salt contamination is preparation and cleanliness standards continue to receive sig-nificant scrutiny; visible standards are only part of the answer to proper Surface preparation for achieving the potential of full life performance of applied protective variables can lead to the interruption of a coating s optimal per-formance.
