Description / Abstract:

This International Standard specifies a small-scale method for assessing the mass loss rate of essentially flat specimens exposed in the horizontal orientation to controlled levels of radiant heating with an external igniter under well-ventilated conditions. The mass loss rate is determined by measurement of the specimen mass and is derived numerically. The time to ignition (sustained flaming) is also measured in this test. Mass loss rate can be used as an indirect measure of heat release rate for many products. However some products, e.g. those with high water content, will have mass loss rates that are not so closely linked to heat release rates. Such products need to be tested in accordance with ISO 5660-1 for correct assessment of heat release.
