Annex D – (normative) – Burning test
D.1 Burning test
The burning test is made in accordance with IEC 60707.
For the purpose of this standard, method FH of IEC 60707 (flame-horizontal specimen), is used.
For the evaluation of the test results, category FH-3 of IEC 60707 applies, the maximum burning rate
being 40 mm/min.
If more than one specimen does not withstand the test, the material is rejected.
If one specimen does not withstand the test, the test is repeated on another set of five specimens, all of
which shall then withstand the test.
