ISO 5660-1 PDF

ISO specifies a method for assessing the heat release rate and dynamic smoke production rate of specimens exposed in the horizontal orientation to controlled levels of irradiance with an external igniter. The heat release rate is determined by measurement of the oxygen consumption derived from the oxygen concentration and the flow rate in the combustion product stream. The time to ignition sustained flaming is also measured in this test. The dynamic smoke production rate is calculated from measurement of the attenuation of a laser light beam by the combustion product stream. Smoke obscuration is recorded for the entire test, regardless of whether the specimen is flaming or not. Check out our FAQs.

Part 1: Heat release rate Cone calorimeter method and smoke production rate dynamic measurement. The test method is used for fire technical modelling. The data from the test results can be used for modelling bigger fires. The method is also widely used in testing at the product development stage. When testing a product according to ISO , a sample with the dimension mm x mm is subjected to a specific irradiance level. The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter.

The emitted gases are collected in a hood and transported away through a ventilation system. The heat release is measured using the data on measured oxygen concentration in the emitted smoke. The smoke production is measured continually throughout the test with a laser system. Levels of toxic gases can also be measured with FTIR analysis. Also attach product and safety data sheets when possible. Order Specification Form.

Cause The test method is used for fire technical modelling. The test method is also used for third party verification production control. The method is cost effective in product development and production control. Method When testing a product according to ISO , a sample with the dimension mm x mm is subjected to a specific irradiance level.

Deliveries A test report, in Swedish or English, is delivered with the test results after testing. RISE have long experience of working with fire safety in railway vehicles. European fire classification of construction products and building elements according to EN The basis of CE-marking of construction products and building elements is the European system of fire testing and classification of products and elements.

The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. The method follows the procedure given in international standard ISO E. Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. The test gives a possibility to evaluate:.
