National annex
NA (informative) Details of laboratory burner
(ignition source P/PF2)
Specifies a small scale laboratory screening procedure for comparing the relative burning behaviour of small specimens of plastics and also their resistance to burn through when exposed to an ignition source of medium energy level (500 W flame). Coverage includes definitions, specimens and precision. Also includes annexes, tables and diagrams.
