The international standards for testing with salt spray prescribe different purity criteria for sodium chloride. While the DIN EN ISO 9227 requires that nickel respectively copper do not exceed 0.0001%, the ASTM B117 calls for a the content of copper to be less than 3 ppm (= 0.00003%). Moreover, the ISO 6353-2 "Reagents for chemical analysis" that replaced JIS K 8150, does not specify any limit values for copper or nickel, but calls for a very low sulphate content: max. 0.002%.
With the introduction of SaliCORR® SP high purity grade of sodium chloride VLM met the requirements of users who need to perform corrosion tests in accordance with very different standards. SaliCORR® SP meets all purity requirements of all standatrds, is naturally free-flowing without the addition of anti-caking agents. This high quality is currently available in 5kg PE bags or 10kg, 20kg or 25kg buckets. Each delivery is accompanied with a batch-related quality certificate.
