Stainless Steel TEST BLOCK (for washability)
The stainless steel test block offers a simple and convenient comparator for monitoring washability of water-wash or post-emulsified penetrants.
The “grit blasted” finish provides a rough surface which will retain background when the removability of a product has decreased when compared to fresh material. The test block should be thoroughly cleaned with SKC-S Cleaner/Remover, as well as periodically refinished (grit blast).
Specifications Compliance: Complies with ASTM E165
