Introduction

Fire-resistant wire and cable or fiber optic cable products are widely used in emergency lines, fire-fighting facilities and fire-fighting and rescue facilities of various construction projects.

When a disaster occurs, it is necessary to ensure the delayed shutdown of important equipment or data backup, to ensure the safe evacuation of various personnel and the normal fire rescue work

Development has a decisive effect on social public safety and reducing fire losses. GB/T 19216 is a fire-resistant wire and cable or optical cable product

A basic evaluation test method for maintaining the integrity of lines under fire conditions. The purpose of GB/T 19216 is to establish for different fire-resistant wires and cables

Or optical cable products and test method standards for different fire test conditions are currently planned to consist of the following 7 parts.

---Part 1.Supply fire with flame temperature not less than 830 degrees C and impose shock vibration, rated voltage 0.6/1kV and below outer diameter exceeding

Pass the test method of 20mm cable. The purpose is to establish that larger diameter wire and cable or optical cable products may be affected by fire.

Part 11, Part 21, Part 23, and Part 25 of GB/T 19216 were formulated in.2003, and they are related to flame temperature.

Test conditions for pure fire supply below 750°C.

GB/T 19216.1, GB/T 19216.2 and GB/T 19216.3, involving the supply of fire with a flame temperature of not less than 830 degrees C and applying shock vibration

The dynamic test conditions are to test power cables, control cables, data cables and optical cables with large and small outer diameters. With refractory power

With the continuous development of wire cable or optical cable technology and the continuous improvement of fire safety requirements, there will be more line integrity test methods in the future

The standards are merged into this series of standards.

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.
