Issues related to the application of explosion-proof product certification
Thread Content
The company has purchased a batch of imported solenoid valves that only possess IEC explosion-proof certification. Can they be installed and used directly in China?
Does anyone know? Could you please explain it?
From a purely technical standpoint, regardless of which organization’s certification is involved, as long as the specified criteria are met, the instrument will certainly satisfy the explosion-proof requirements. For example, instruments that have already passed explosion-proof certification in the United States – what’s the need to go through the certification process again and again in countries like Japan, Vietnam, and other powerful nations? However, the technical logic of the objective world is not what is described in textbooks; for example, the test results conducted by two hospitals in the same city may not be recognized by each other. When you go to see a doctor, those tests might just be a gimmick – all that matters is money! Got it? So the technology I’m talking about doesn’t count either. You have to listen to your boss; if the boss says it’s okay, then it’s okay, and if the boss says no, then it’s not okay. Answer completed.
Check what was stipulated in the cooperation agreement you signed at that time. Personally, I think it can be used.
I remember that in theory it’s not possible, but IEC and NEPSI recognize each other’s certifications; so as long as a certificate is issued by NEPSI, no tests are needed – it’s simple. It is recommended to take a look at the appendix of GB3836.
It is actually possible, unless the contract requires domestic certification at that time.
It should be ready for use; the domestic standards are all formulated based on IEC
In accordance with China’s requirements, products that have foreign explosion-proof certifications must be converted into domestic explosion-proof certification certificates before they can be sold and used in China
GB3836 was formulated with reference to IEC – so what’s wrong with that? Just pay attention to the equivalence of explosion protection ratings.
Explosion-proof equipment comes with an explosion-proof rating; if it is below the requirements of the site, it cannot be used
GB3836 was formulated with reference to the IEC standard. What’s wrong with that? ? Pay attention to checking the equivalence between the GB and IEC explosion protection ratings; as long as the explosion protection requirements are met, it is sufficient.
