This part of IEC 60695, which is a Technical Specification, specifies a fire containment test method for finished units. It is intended to verify the capability of containing of a fire event generated by an effective ignition source inside a finished unit.

Unless otherwise specified by the relevant product standard, determination of the fire containment described in this document does not apply to any of the following:
• A single electrical component;
• A single electrical component when incorporated into a finished unit;
• Electrical installation products such as distribution boards, circuit protection devices, switchgear, controlgear, cable management system and electrical accessories (wiring devices).

The test method described in this document does not apply to the following electrical connections:
• Low-power electrical connections contained in finished units, where the maximum power through the connection does not exceed 15 W.
• Soldered and welded electrical connections are exempted from the evaluations of this document.

This document is intended to be used for evaluating the capability of fire containment of finished units, during the selection of finished units and in the design of finished units.
