GB/T 18380.13-2022 is the English-translated version of 电缆和光缆在火焰条件下的燃烧试验第13部分：单根绝缘电线电缆火焰垂直蔓延试验测定燃烧的滴落（物）/微粒的试验方法.

GB/T 18380.13-2022 is the Chinese standard "Tests on electric and optical fibre cables under fire conditions - Part 13: Test for vertical flame propagation for a single insulated wire or cable - Procedure for determination of flaming droplets/particles".

Its scope clause reads: This document describes the tests for the evaluation of drips/particulates from the burning of a single insulated wire or cable or fiber optic cable under specified flame conditions method.

Note. If necessary, carry out the test of this document and the test of GB/T 18380.12 simultaneously. Appendix A gives recommended performance requirements. This document specifies the general usage of the 1kW premixed flame, and is not suitable for testing small-scale singles with a total cross-sectional area less than 0.5mm2.

A wire and cable, because its conductors will be melted before the end of the test, nor is it suitable for thin fiber optic cables, because the fiber optic cable will break before the end of the test. Its clauses include terms and definitions.
