Do explosion-proof electrical devices need to have their explosion-proof properties tested regularly during use?
Thread Content
In chemical manufacturing plants, it is very common to use electrical equipment with explosion-proof properties in areas where there is a risk of fire and explosion. Moreover, these explosion-proof electrical devices are used for many years, even over a decade, until they need to be replaced. I would like to ask the experts in electrical technology: when using explosion-proof electrical equipment, how can we ensure its reliable explosion-proof performance? Is regular testing required? How to conduct explosion-proof performance testing? I would be grateful for your advice! I can only reward with a rating: lol:handshake
Recently, I talked with a friend named Jiaocan; he is involved in the testing of explosion-proof electrical equipment and instruments in cities in Shandong and the eastern coastal areas, and he issues reports. I’m not sure if this is the type of inspection service the original poster is looking for. Also, I haven’t clarified which standards are used for such testing
Entrust a professional testing agency (with relevant qualifications) to conduct tests once every three years; various standards apply, including AQ-3009, GB50058\50257\50160\3836\50169, DL664, SH3097\3038, and HG20675
It is entrusted to a third-party agency, with inspections conducted once every three years
It seems that actions in this regard are indeed being taken, and as for regulations, they will be established soon
Well, there’s so much of it; I need to study it carefully*

This group employs hundreds of thousands of workers and has numerous chemical plants; for explosion-proof electrical equipment such as motors, distribution boxes and cabinets, lighting fixtures, etc., it is sufficient to ensure they are in good condition, with no testing for explosion-proof performance being conducted. However, the inspection requirements are very strict – if a single piece of explosion-proof electrical equipment fails to meet the standards, a red flag is issued and the entire factory must stop operations for corrective actions.
It’s only in recent years that people have started to pay attention; the regulations already existed long ago.
According to AQ3009-2007 requirements, testing should be carried out at least once every 3 years
