scope:

IEC 60695-8-3, which is a technical specification, specifies quantitative test methods for determining the heat release from the combustion of insulating liquids of electrotechnical products when exposed to a defined heat flux with spark ignition. Smoke production, ignition times and mass loss are also measured. This technical specification may also be applicable to other liquid test specimens.

This technical specification is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and in ISO/IEC Guide 51.

One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.

HAZARD WARNING

The testing of volatile liquids with this apparatus can lead to explosions so it is essential to examine all liquids using the preliminary testing procedure described in 8.1.
