Leneta-ASTM Scrub Media
These are aqueous dispersions of detergent, cellulosic thickener and preservative, made in conformance with and approved for use in the indicated ASTM methods. The abrasive type contains ground silica for accelerated erosion. The two compounds are representative of the detergent and abrasive character of commercial cleaning products. Because of the variable nature of their ingredients, Leneta Company provides media adjusted and tested to assure batch-to batch uniformity. Each container is fully identified by batch number and shipping date. The contents of unopened containers are guaranteed standard in performance for a year, which is highly conservative on the basis of observed package stability. Supplied in pint (473 mL) jars, sufficient for about 40 tests.
