Chlor*Test A Chloride Ion Test Kit for Abrasives

Chlor*Test-A Kit by Chlor*Rid International is a self-contained soluble salt test kit containing everything needed for simple and accurate measurement of chlorides in abrasive blast media. ChlorTest A gives values in both parts per million (ppm) and micrograms per centimetre squared (µg/cm2).

Many coatings have failed from chlorides deposited on a surface by contaminated abrasive. Chlor*Test A makes on-site testing of abrasives before blasting possible. Self-contained and easy-to-use, Chlor*Test A provides accurate results in minutes;  no need to send samples to a laboratory, no waiting days for results, no high cost! Chlor*Test A can be used to test any abrasive for contamination by chloride salt.

Cross-contamination, from test to test, is eliminated through one-time use of individual test components. The components are pre-measured to ensure accurate results in parts per million (ppm). In addition, no temperature correction is needed from 41ºF to 176ºF. Chlor*Test A uses ASTM D4940* principals, but offers the additional value of chloride ion specific measurements.

Testing abrasives for soluble salts is easy with ChlorTest A:


Collect the measured sample of abrasive in the container supplied.



Pour the measured abrasive into the pre-measured jar of ChlorTest solution; replace the lid tightly, and vigourously shake the container for 2 minutes. Allow the mixture to sit for about 5 minutes, or until there is about 1/2 inch of clear solution at the top of the jar. Do not proceed before this has settled out.




Snap the ends off the glass titrator tube and insert the arrow end into the clear solution at the top of the sample. In about 2 minutes, the colour change will indicate the chloride levels present in the sample.







Each Chlor*Test-A kit contains four (4) individual tests. Bulk packs with 40 tests are also available.
