    2 Moisture values can be interpreted in several units; parts per million by volume (PPM v), parts per million by weight/mass (PPM w or PPM m), dew point (C& or F&), and relative humidity (RH). Decomposition Although SF 6 is non-toxic in its pure form, it will decompose when exposed to high temperature or electrical arcing – especially in the presence of moisture.
