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:

ASTM D1308
(Chemical Resistance, 50% immersion, room temperature)

  • Sulfuric Acid – 3%, 10%, 20% & 50%
  • Sodium Hydroxide – 5%, 25% & 50%, including 25% @ 140° F.
  • Hydrochloric Acid – 10% & 30%
  • Hydrogen Peroxide – 10%, 20% & 35%
  • Sodium Chloride – 5% @ 120° F. aerated
  • Distilled Water – Ambient and @ 160° F.
  • Gasoline
  • Toluene
