Testing
Permox-CTF™ has been extensively tested for years by PPC Labs, other Independent Testing Firms and Ductile Iron Manufacturers. Successful and impressive test results were obtained and are well documented. The testing matrix for Permox-CTF™ is too numerous to list here. Some of the more recognized industry standards Permox-CTF™ meets or exceeds are listed below:
