ISO 6942-2002,EN 366,GA 10-2014
Instrument Features:
According to the ISO 6942-2002 (EN366) standard, the protection of
the material can be tested according to two test methods.
The first method (method A) is that the sample is subjected to a
certain amount of heat radiation, and in order to reproduce the
harsh conditions of the material, the appearance change is
recorded.
The second method (method B) is to place the calorimeter on the
back of the sample, the heat is conducted out from the back of the
sample, and the trend of temperature change with time is recorded
to determine the level of heat radiation transfer.
