A2L Refrigerants and ASHRAE® Standard 15

The HVAC&R industry is in the midst of another refrigerant transition. Some of the newer refrigerants under consideration are designated as having “lower
flammability” (Class 2L), indicating that they can ignite under certain conditions. Building codes and industry standards (such as ASHRAE Standard 15) have been updated to include safety requirements that reflect the less-flammable nature of Class 2L refrigerants.
