Foreword

GB/T 18380 "and optical fiber cables under fire conditions test" is divided into 11 parts. --- Part 11. single insulated wire and cable vertical flame spread test test equipment; --- Part 12. single insulated wire and cable flame test 1kW pre-mixed flame test methods vertical spread; --- Part 13. single insulated wire and cable vertical flame spread test measures the burning dripping test methods (substance)/particles; --- Part 21. single small insulated wire or cable vertical flame spread test test equipment; --- Part 22. single small insulated wire and cable flame test diffusion flame test methods vertical spread; --- Part 31. Vertical bunched wires or cables installed vertical flame spread test test equipment; --- Part 32. Vertical bunched wires or cables installed vertical flame spread test AF/Class R; --- Part 33. bunched wire and cable flame spread of vertically-mounted vertical test class A; --- Part 34. bunched wire and cable flame spread of vertically-mounted vertical test class B; --- Part 35. bunched wire and cable flame spread of vertically-mounted vertical test class C; --- Part 36. Vertical bunched wires or cables installed vertical flame spread test class D. This section GB/T 18380 of Part 22. This section identical with IEC 60332-2-2.2004 "Burning Test Part 2-2 and optical fiber cables under fire conditions. Single extermination Margin thin wire cable vertical flame test diffusion flame test methods "(in English) spread. For ease of use, this section made the following editorial changes. a) Remove the foreword and introduction of international standards; b) increase in the foreword to the national standard of this Part; c) use a decimal point instead of a decimal comma ",". ","; d) with "Part 22" instead of "Part 2-2"; e) Part 2 of this chapter refers to the use of international standards, rather than national standards with international standards in China. Appendix A of this section is an informative annex. This part is proposed by the China Electrical Equipment Industrial Association.

1 Scope

GB/T 18380 provisions of this section under fire conditions, a single small insulated wire or cable thin cable vertical flame spread test method. Test equipment specified in 18380.21-2008 in GB/T . When the test method GB/T 18380.12-2008 shall not apply, such as during the test for the fire may break the thin cable or conductor may Can thin wire fusing. This standard recommends testing thin cable, the total cross section of less than 0.5mm2 insulated wire and cable. Note. The use of this standard in line with insulated wire and cable is not sufficient to prevent flame spread all laying conditions. In some high-risk situations, such as When the beam length of wire large vertical laying of a sample can not be considered consistent with the standard performance requirements, from the types of wire bundle will show the same sex Energy (see GB/T 18380.31 ~ 36 series of standards). Recommended performance requirements in Appendix A.
