Method of test for burning velocity measurement of A2L flammable gases

This document specifies a method of measuring the burning velocity (BV) of slowing burning refrigerants (<?10?cm/s) for use with other standards that utilize the BV for determining safety classification of refrigerants (e.g. ISO 817) or that use the BV in establishing requirements on the use of slow burning refrigerants (e.g. ISO 5149).
