GB/T 4610-2008 in English

《GB/T 4610-2008塑料 热空气炉法点着温度的测定》由TC15（全国塑料标准化技术委员会）归口，TC15SC4（全国塑料标准化技术委员会通用方法和产品分会）执行，主管部门为中国石油和化学工业联合会。
本标准规定了热空气炉法测定塑料闪燃温度和自燃温度的试验方法。它是评价塑料着火性能的方法之一。

Scope

This standard specifies the test method for determining the flash ignition temperature and autoignition temperature of plastics by hot air furnace method. It is one of the methods to evaluate the fire performance of plastics. This standard does not directly measure the burning value or burning rate of materials, or give the upper limit temperature of safe use of plastics. It cannot be used to describe or evaluate the hazards and risks of materials, products or finished products in actual fires. However, test results can be used as a factor in all relevant factors for fire hazard and risk assessment. The tests specified in this standard can be used to evaluate the relative fire performance of different materials. The values obtained under the test conditions represent the lowest ambient temperature at which the material can catch fire. The test results can be used as the basis for the classification of material fire sensitivity grades.
