This test program includes all tests required for ASTM D-2472 / IEC sulfur hexafluoride (SF₆) purity specifications on new or reclaimed-purified liquified SF₆. Sampling can be performed on customer supplied DOT rated cylinders, passivated cylinders rented from ALI (both require proper hazmat shipping) or sampled with our special, low-pressure / no emission “No-Haz” SF₆ Sampling Kit which allows for proper SF₆ sample shipping as a non-hazmat.
