1 Scope

GB/T 26950.2-2025 is the Chinese national standard covering the diesel or LPG forklift certified for an explosive atmosphere - flame traps on the intake and exhaust, surface temperatures held below the ignition point of the gas outside, the electrical system enclosed, and a shutdown that works when the engine tries to run on the atmosphere itself. Part 2 of the series. It replaces GB/T 26950.2-2015, revised together with Part 1 on battery trucks. It was issued on 31 December 2025 and has been in force since 1 July 2026, replacing GB/T 26950.2-2015. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the technical requirements, test methods, inspection rules, markings, accompanying documents, transportation, and other aspects for explosion-proof internal combustion industrial vehicles. Storage. This document applies to internal combustion industrial vehicles used in Zone 1, Zone 2, Zone 21 and Zone 22 explosive atmospheres. This document does not apply to internal combustion industrial vehicles used in gas explosive atmospheres and ammunition dust atmospheres.
