21 Explosion-proof Certification Execution Standard Application Process

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.
Why choose tempered glass for explosion-proof transparent parts?
Transparent components are an important material for explosion-proof electrical equipment. When selecting transparent components, customers always inquire about the material to be used? Is glass acceptable? Is plastic acceptable?
Below, Shenzhen ZhongNuo Inspection Technology Co., Ltd. explains it for you.
GB/T3836.1 explicitly stipulates the thermal shock test for transparent components, which aims to verify the thermal stability of glass under rapid cooling conditions. Currently, tempered glass is a material that not only meets this requirement but also offers high cost-effectiveness.
To普及，tempered glass forms an even compressive stress layer on the surface after being heat-treated and quenching, which counteracts the tensile stress generated on the surface during rapid cooling. Therefore, even when subjected to rapid cooling, qualified tempered glass will have a compressive stress to offset the stress.

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.
Issue explosion-proof certificates for products that meet the GB/T3836 standard.
Current domestic explosion-proof certification standards are essentially equivalent to the international IEC 60079 standard system.

What are the conditions and documents required to apply for an explosion-proof certification?
The explosion-proof certificate is a safety certification for equipment and products used in environments with explosive gases or combustible dust.
Certificates are available for Ex equipment and Ex components.
Products require a防爆certification, and a防爆standard test must be provided for the product.
Provide drawings and documentation that meet explosion-proof standards.
The technical documentation here includes product manuals, corporate standards, electrical schematics, PCB layouts, assembly drawings, exploded views, battery testing reports and specifications, casting and sealing process files, wireless transmission power reports, and shell material reports, among others.
Of course, not all of this information is required; it depends on the product structure and explosion-proof type for further assessment.
ZhongNuo Inspection has years of experience in explosion-proof product testing and certification services.
We offer consulting services for explosion-proof design, drafting, circuit, and structural modifications. We provide full-process consulting services for obtaining explosion-proof certification. Welcome to consult at any time!

IECEx Certification
IECEx is an explosion-proof electrical products certification system advocated by the International Electrotechnical Commission (IEC).
The purpose is to eliminate discrepancies in equipment and services used in explosive environments, to promote international trade.
Maintain the level of equipment safety requirements. The current explosion-proof standard is IEC 60079.
IECEx certification has now become a route for products used in all hazardous areas to obtain international safety certification.
Currently available in many countries worldwide (Australia, New Zealand, Brazil, Canada, China, Japan, South Korea, Malaysia, Singapore, South Africa, the United States, etc.).
The IECEx certified certificates will be automatically uploaded to the IECEx website, where manufacturers and end-users can find the relevant documents.
