Standard IEC60335-2-6 clause 22.120 , IEC60335-2-24 clause 22.116

IEC60335-2-6 clause 22.120

glass panels of oven doors and glass in hinged lids of hobs shall be made from

–glass that breaks into small pieces when it fractures; or

–glass that is not released or dropped from its normal position when broken.

The sample under test is broken by means of a test punch having a head with a mass of 75 g± 5 g and a conical tungsten carbide tip with an angle of 60° ± 2°. The punch shall be positioned approximately 13 mm in from the longest edge of the glass at the midpoint of that edge. The punch is then hit by a hammer so that the glass breaks.
