With the release and implementation of the new version of the national standard GB/T3836-2021, domestic explosion-proof standards have further aligned with international explosion-proof standards. The new version of the national explosion-proof standard combines the original GB12476 and GB25286 standards, covering various aspects such as design, manufacturing, inspection, selection, installation, inspection, maintenance, repair, and site classification of equipment used in explosive environments. It adopts a segmented standard form, including but not limited to the following parts.
