WebFor flammability, there are three classifications and one subclass. The three main flammability classifications are class 1, for refrigerants that do not propagate a flame when tested as per the standard; class 2, for refrigerants of lower flammability; and class 3, for highly flammable refrigerants such as the hydrocarbons. WebNov 27, 2024 · The toxicity classification for refrigerants is either lower toxicity (Class A) or higher toxicity (Class B), based on the refrigerant itself as a direct hazard and not based upon the combustion byproducts. Table 1 compares a representative refrigerant in four of the safety groups (combined toxicity and flammability classifications).
WebThe toxicity and flammability classifications described in Sections 6.1.1, 6.1.2, and 6.1.3 yield six separat e safety group classifica-tions (A1, A2, A3, B1, B2, and B3) and two sub-classes (A2L and B2L) for refrigerants. These classifications ar e represented by the matrix shown in Figure 1. 6.1.5 Safety Classification of Refrigerants WebHazard classification for flammable liquids Class: Flash point: Boiling point: Examples: I-A: below 73°F (23°C) below 100°F (38°C) diethyl ether, pentane, ligroin, petroleum ether: …
