标准范围

ISO/TR 834-2:2009确立了测量按照ISO 834-1要求测试样品的炉内暴露均匀性的一般原则。ISO/TR 834-2:2009规定了用于测量模拟试样表面附近温度、速度和氧含量的仪器的类型和位置。面向熔炉的模拟样品表面是石膏板，固定在冷弯型钢支架上。ISO/TR 834-2:2009不包括熔炉性能要求。

ISO/TR 834-2:2009 establishes general principles for measuring the uniformity of furnace exposure of samples tested in accordance with the requirements of ISO 834-1. ISO/TR 834-2:2009 specifies the type and location of instrumentation used to measure the temperature, velocity and oxygen content near the surface of simulated test samples. The surface of the simulated sample facing the furnace is gypsum board secured to cold-formed steel supports.ISO/TR 834-2:2009 does not include requirements for furnace performance.
