Sodium chloride meeting ASTM B117 requirements

Can anyone suggest sources for sodium chloride meeting the requirements set by ASTM B117? The common CP and AR reagents do not indicate that they meet the requirement of <0.3 ppm for Copper!

Ed. note: Sorry, this RFQ is outdated, and contact info no longer available; but technical replies are welcome. No commercial suggestions please ( huh? why?)

Ed. note: Most plating process distributors will have this product. If difficulty in sourcing continues, please contact the firms shown in the banner above.

I suggest to analyse your AR salt for the level of Cu.
