GB/T 18380.36 - 2022 conducts class D flame vertical spread test for vertically installed bundled Wires and cables. This standard describes the test principle, specifies the requirements of combustion device and fire source characteristics for class D test, and clarifies the selection and installation specifications of the sample. Standardize the test process, including ignition time and flame spread observation points. With this standard, it is possible to accurately evaluate the vertical spread of bundled Wires and cables under class D flame conditions, providing a unified detection method for cable production, power communication and other industries, helping to improve the safety of cables in fire environments and ensure the stable operation of related systems.
