GB/T 19216.2-2021 Active

This document describes the test method for fire-resistant cables to maintain line integrity when subjected to flames and impact vibration under specified conditions. This document is applicable to cables with a rated voltage of 0.6/1 kV and below, including metal conductor data with a rated voltage below 80 V, as well as telecommunications cables and optical cables. This document is applicable to test cables with an outer diameter of less than or equal to 20 mm. Cables with larger diameters will be tested using the equipment, procedures, and requirements of GB/T 19216.1. This document describes the test failure points, continuity inspection devices, test samples, test procedures, and test reports for rated voltage 0.6/1 kV and below power cables and control cables in detail. The test failure points, continuity inspection devices, test samples, test procedures, and test reports for metal conductor data and telecommunications cables and optical cables are not provided. Although the scope of application is limited to cables with a rated voltage of 0.6/1 kV and below, it can also be applied to cables with a rated voltage of 1.8/3(3.3) kV and below when the manufacturer and buyer agree and are equipped with suitable fuses. Appendix A provides a verification method for the test burner and control system. When identifying markings is necessary, markings can be selected on the cables to indicate compliance with this document. Warning: The tests in this document may involve the use of dangerous voltages and temperatures. Appropriate precautions should be taken to prevent potential risks of electric shock, combustion, fire, and explosion, as well as any harmful gases that may be generated.
