Specifies the test requirements related to thermal release mechanisms used in fire dampers tested according to ISO 10294-1. Only the thermal release mechanism is subjected to the tests described in this standard. The methods of test are designed to ensure that under fire conditions the thermal release mechanism complies with the expected functions so that the damper will close completely so as to prevent the spread of fire. Also included is a method for ensuring that the thermal release mechanism does not close the damper in non-fire conditions. The effect of corossion on the operational reliability of the release mechanisms is also evaluated. This method is applicable for thermal release mechanisms installed within the damper or duct. The test can provide information on comparative performance between one thermal release mechanism and another and thus provides for the testing of thermal release mechanisms that have not been included in the damper assembly that was tested to ISO 10294-1.
