标准范围

本文件规定了一种测试方法，适用于分析根据ISO 5659-2测试的样品和产品在热解和燃烧过程中产生的废水。规定的试验方法基于ISO 19702中描述的傅里叶变换红外（FTIR）光谱，以及适用于该物理火灾模型的试验装置和分析仪校准的附加信息。本文件旨在与ISO 5659-2和ISO 19702结合使用。该试验方法在整个ISO 5659-2试验期间提供时间分辨气体浓度。本文件不涉及任何产品应用中该火灾模型的准确性，也不涉及任何实际规模火灾试验或火灾场景中气体浓度的准确性。为了将来将本文件转换为国际标准，拟进行实验室间试验，以取代附录B。本文件不包括任何毒性评估，也不提供消防安全工程的输入数据。由于在ISO 5659-2测试期间，燃烧条件取决于外壳中的氧气消耗率，因此该物理火灾模型不能代表任何特定火灾场景。因此，很难将试验结果与实际火灾条件进行比较。因此，如果本试验方法用于材料或产品之间的比较，则应结合其他耐火试验进行。

This document 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 analyser calibration suitable for its application to this physical fire model. This document is intended to 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 document 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. For future conversion of this document into an International Standard, an interlaboratory trial is intended to be conducted to replace Annex B.This document 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 intended to be done in combination with other fire tests.
