Many customers have asked us if non electrical equipment used in explosive environments needs to obtain explosion-proof certification? According to what standards? What are the precautions for explosion-proof certification of non electrical equipment? wait.

In response to these issues, Zhongnuo Testing summarizes its past experience in obtaining explosion-proof certification and provides a brief explanation of which non electrical equipment requires explosion-proof certification and the requirements for handling it.

In explosive environments, non electrical equipment such as couplings, gearboxes, brakes, hydraulic and pneumatic motors are often used. These devices are often accompanied by high-speed motion and friction components during operation, which pose a risk of ignition sources such as sparks, arcs, and high temperatures. Therefore, when used in explosive environments, the explosion-proof performance of the equipment needs to be considered.

The reference standards for explosion-proof certification of non electrical equipment are mainly GB/T 3836.1, GB/T 3836.28, and GB/T 3836.29.

A comprehensive ignition hazard assessment of the entire mechanical equipment is an important design point for non electrical equipment explosion-proof certification.

Zhongnuo Testing has been specializing in explosion-proof certification consulting services for many years, and has also successfully obtained explosion-proof certification for many non electrical equipment, including gearboxes, exoskeleton equipment, mechanical seals, torque limiters, etc. If you have any consultation needs in this area, please feel free to message us at any time!
