GB/T 19216.2-2021Circuit integrity test for electric cables or optical fiber cables under fire conditions - Part 2: Test method for fire with shock at a temperature of at least 830 degrees C for cables of rated voltage up to and including 0.6/1 kV and with an overall diameter exceeding 20 mm (English PDF)

GB/T 19216.2-2021 is the English-translated version of 在火焰条件下电缆或光缆的线路完整性试验 第2部分：火焰温度不低于830 ℃的供火并施加冲击振动，额定电压0.6/1 kV及以下外径不超过20 mm电缆的试验方法.

GB/T 19216.2-2021 is the Chinese standard "Circuit integrity test for electric cables or optical fiber cables under fire conditions - Part 2: Test method for fire with shock at a temperature of at least 830 degrees C for cables of rated voltage up to and including 0.6/1 kV and with an overall diameter exceeding 20 mm".

Its scope clause reads: This document describes the test methods for maintaining the integrity of the circuit when fire-resistant cables are subjected to flame and shock vibration under specified conditions.

This document applies to cables with a rated voltage of 0.6/1kV and below, including metal conductor data and telecommunications with a rated voltage below 80V Electric cables and optical cables.

This document applies to test cables with an outer diameter less than or equal to 20mm. 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 check devices, and test points of power cables and control cables with a rated voltage of 0.6/1kV and below.

Detailed information of the test samples, test procedures and test reports. The metal conductor data and the test failure point and continuity of telecommunications cables and optical cables are not given.

Detailed information about the test equipment, test samples, test procedures and test reports.

Although the scope of application is limited to cables with a rated voltage of 0.6/1kV and below, when the manufacturer and the buyer agree, and are equipped with suitable After the fuse, it can also be applied to cables with a rated voltage of 1.8/3(3.3)kV and below.

Appendix A gives the verification method of the burner and control system used in the test. When you need to identify the mark, you can choose to mark on the cable to indicate compliance with this document.

Caution. The tests in this document may involve the use of dangerous voltages and temperatures. Appropriate precautions should be taken to prevent possible Risks of electric shock, burning, fire and explosion, as well as any harmful gases that may be produced. Its clauses include terms and definitions.
