ISO/TR 834-2:2009

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.
