Shenzhen ZhongNuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
Can optical fiber temperature measurement products undergo explosion-proof certification? What are the requirements?
Fiber optic temperature sensing products primarily monitor temperature through sensing fibers, offering high accuracy, immunity to electromagnetic interference, and real-time online capabilities.
If this optical fiber is emitted into an explosive hazard area, the possibility of the light causing an explosion must be considered, and explosion-proof certification should also be taken into account.
The execution standards for explosion-proof certification of fiber optic temperature measurement products are GB/T 3836.1 and GB/T 3836.22.
Primarily considering the product's circuit and the laser generator's emission power.
Shenzhen Zhongnuo Inspection has successfully obtained multiple explosion-proof certificates and coal safety certifications for customers in the field of fiber optic temperature measurement master units.
We have accumulated extensive experience in certification and can provide consulting services for explosion-proof product design modifications, drawing guidance, and certification.

Domestic explosion-proof certification
Domestic explosion-proof certification is a compliance inspection for explosion-proof products used in explosive environments (including electrical and non-electrical products), issuing an explosion-proof certificate for products that meet the GB/T3836 standard. Currently, the domestic explosion-proof certification standards are essentially equivalent to the international IEC60079 standard system.

Many customers inquire during consultations about the difference between obtaining explosion-proof certification and an explosion-proof qualification certificate for a product.
explosion-proof certification and explosion-proof compliance certificate are two different concepts; after a product undergoes explosion-proof certification, the final result is an explosion-proof compliance certificate.
Explosion-proof certification is the process, and the explosion-proof certificate is the result.
So the customer mentioned that the product needs to obtain a explosion-proof certification or a explosion-proof compliance certificate, which means the product must pass the relevant explosion-proof standard tests and meet the standard requirements to obtain the explosion-proof compliance certificate.
Explosion-proof certifications can be categorized according to different types of explosion protection, such as intrinsic safety, flameproof, positive pressure, and cast resin.
ZhongNuo Inspection boasts a team of explosion-proof engineers capable of providing initial design services for explosion-proof circuits and structures. We also assist enterprises in compiling the necessary drawings, technical specifications, and corporate standards required for explosion-proof certification, facilitating their smooth acquisition of the explosion-proof qualification certificate.

What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification for the European Union market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to various certification directives; the ATEX directive is specifically for explosive-proof equipment and products.
ATEX certification can be considered as the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive applies to the EN60079 series.
Different explosion-proof types are applicable to different standard series.
For example, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is for increased safety, EN 60079.11 is for intrinsic safety, and so on.
