Introduction

Flame retardant wire and cable or optical cable products are widely used in various construction projects.

It is of great significance to reduce the occurrence of disasters and the spread of flames, reduce fire losses, and ensure the safe evacuation of all kinds of people. GB/T 18380 aims to establish

The test method for the flame retardant performance of different flame retardant wire and cable or optical cable products under different installation and laying conditions is planned to be composed of 11 parts.

--- Part 11.Test device for vertical spread of flame for a single insulated wire and cable. The purpose is to specify for single insulated electrical

Test device for vertical flame spread test of wire and cable.

--- Part 12.Single insulated wire and cable flame vertical spread test 1kW premixed flame test method. the purpose is

Test method for determining the vertical flame spread of a single insulated wire or cable or fiber optic cable under 1 kW premixed flame conditions.

--- Part 13.Test method for vertical flame spread of a single insulated wire and cable to determine burning drips (objects)/particles.

The purpose is to determine the test for the determination of burning drips (objects)/particulates in the vertical flame spread test of a single insulated wire and cable

method.

--- Part 21.Test device for vertical flame spread test of a single insulated thin wire and cable. Intended to be specified for single insulation

Test device for vertical flame spread test of thin wire and cable.

--- Part 22.Vertical flame spread test method for single insulated thin wire and cable Diffusion-type flame test method. The purpose is to determine the total

Insulated thin wires and cables with a cross-section less than 0.5mm2 and thin optical cables or conductors that may break under 1kW premixed flame conditions

Test method for vertical spread of flame on thin wires that may fuse.

--- Part 31.Vertically installed bundled wire and cable flame vertical spread test test device. The purpose is to provide for vertical

Test device for vertical flame spread of straight-mounted bundled wires and cables, and installation arrangement and calibration.

--- Part 32.Vertically installed bundled wire and cable flame vertical spread test AF/R category. The purpose is to determine the applicable

Test method for the ability of special cables to be used in special installations to inhibit the spread of flame when installed in vertical bundles.

--- Part 33.Vertical flame spread test of bundled wires and cables installed vertically Class A. The purpose is to determine the

Test for the ability of wire, cable or optical cable products to inhibit the spread of flame when installed in vertical bundles in the case of metal material volume content

method.

--- Part 34.Vertical flame spread test of bundled wires and cables installed vertically Class B. The purpose is to determine the medium for rating

Test on the ability of wire, cable or optical cable products to inhibit the spread of flame when installed in vertical bundles in the case of non-metallic material volume content
