Scope

Refrigerant stability evaluation method and criteria for disproportionation (explosive decomposition) reaction

- Test apparatus

- Test conditions

- Judging criteria

Purpose

Unsaturated HFCs refrigerants are preferred to reduce or to eliminate global warming potential of refrigerants. However, some of them can cause explosions due to its lower stability. So, they are usually used as a component of blend refrigerants. This standard will provide test methods and criteria to ensure safe composition of such blends.
