Gives detailed requirements for the production of a 1 kW nominal, propane-based premixed test flame, its approximate overall height being 175 mm. This Standard is technically equivalent to and reproduced from IEC 695-2-4/1:1991.

This section of IEC 695-2 gives the detailed requirements for the production of the 1 kW nominal, propane based pre-mixed type test flame. The approximate overall flame height is 175 mm.This section should be used in conjunction with IEC 695-2-4/0 and the other guidance publications in IEC 695.
