This International Standard specifies a test method suitable to analyse effluents produced during pyrolysis and combustion of samples and products tested according to ISO 5659-2. The specified test method is based on Fourier-transform infrared (FTIR) spectroscopy described in ISO 19702, with additional information on the test apparatus and analyzer calibration suitable for its application to this physical fire model. This International standard shall be used in conjunction with ISO 5659-2 and ISO 19702. The test method provides time-resolved gas concentrations during the whole of an ISO 5659-2 test. This International Standard does not address the accuracy of this fire model for any product application, nor does it address the accuracy of the gas concentrations relative to any real-scale fire tests or fire scenarios. This International Standard does not include any toxicity assessment or provide input data for fire safety engineering. As combustion conditions vary depending on the oxygen consumption rate in the enclosure during the ISO 5659-2 test, this physical fire model is not recognised as being representative of any specific fire scenario. Therefore, it is difficult to compare test results with real-scale fire conditions. As a consequence, if this test method is used for comparison among materials or products, it is be done in combination with other fire tests.
