GB/T 18380.34 - 2022 Perform flame vertical spread test (Class B) for vertically installed bundled Wires and cables. The standard specifies the test principle, specifies the combustion equipment and fire source parameters for Class B test, and specifies the sample preparation, such as cable selection and Installation method. Standardize the test process, including ignition duration, flame observation and measurement. Through this standard, the vertical spread characteristics of bundled Wires and cables under Class B flame conditions can be accurately evaluated, providing unified detection methods for cable production, power communication and other industries, helping to improve the safety of cables in fire scenarios.
