The ATS Series 510 and 520 Sealing Compound Testers have been designed to test the durability of joint sealants in load capacities up to 1,000 lbf (4.44 kN). Both machines are capable of determining Aymar durability and performing other constant-speed tests per ASTM and U.S. Federal specifications. The Series 520 also performs variable-speed testing per JIS and other standards.
