This standard serves as the core foundational component of the "glowing/hot-wire" test methods within the series of fire hazard tests for electrical and electronic products. It specifies in detail the structure of the equipment used for the glow-wire test, calibration requirements, and the general test procedures applicable to subsequent methods (such as Part 11: Flammability tests for finished products). The standard outlines the technical requirements for the glow-wire head (made from a specific nickel-chromium alloy wire), the heating current control system, the thermocouple temperature measurement system, and the timing device. It also defines standardized general procedures, including pre-test preparation, application of the heat source, observation, and recording. The essential equipment for implementing this standard and conducting related tests is a dedicated glow-wire test apparatus, which must meet all the above specifications to ensure comparability of test results across different laboratories.
