For gas explosion-proof protection, the national standard adhered to is GB3836. This standard specifies the criteria and guidelines necessary for ensuring safety in environments where explosive gases may be present, ensuring that the junction boxes can operate safely without igniting any potentially hazardous atmosphere.

In the case of dust explosion-proof protection, the relevant national standard is GB12476. This standard outlines the requirements for safe operation in environments where combustible dust may accumulate. It ensures that the junction boxes are capable of preventing any ignition source from coming into contact with combustible dust, thereby maintaining safety in such environments.
