Process for applying for the whole machine explosion-proof certificate for climbing wall robots - Shenzhen Zhongnu Inspection

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 one-stop explosion-proof technology consulting services.
Classification of Explosion-Proof Certification -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
Blastproof certification is the process of determining if equipment meets the requirements of blastproof standards, type testing, and applicable routine tests, and issuing the relevant qualification certificates.
Certificates are available for Ex equipment or Ex components.
Different regions have varying certification standards and systems for explosion-proof electrical products.
Currently, explosion-proof certifications internationally can be categorized into domestic explosion-proof certifications, ATEX certifications, IECEx certifications, and North American explosion-proof certifications.

Division of Explosion-Proof Areas in Combustible Dust Environments -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Explosive certification divides hazardous areas into areas with flammable gas environments and combustible dust environments based on the different physical states of substances present at the site. Based on the duration of presence of hazardous substances in the site, the hazardous areas under the two different physical states are divided into three zones.
For environments with combustible dust, it is for Zones 20, 21, and 22.
Areas in Zone 20 where flammable dust environments occur continuously or persist for extended periods, typically exceeding 1000 hours per year.
Zone 21 - Areas where potentially explosive dust atmospheres may occur during normal operation, typically 10-1000 hours/year
Zone 22 - Under normal operation, flammable dust environments are not possible or only occasionally present for short periods, generally less than 10 hours per year.

Division of explosion-proof areas in explosive gas environments
Explosive areas are classified into explosive gas environments and combustible dust environments based on the physical state of substances present in the location. These areas are further divided into three zones according to the duration of presence of hazardous substances in the location, across different physical states.
That is: for explosive gas environments, 0 Zone, 1 Zone, and 2 Zone.
Zone 0: Areas where explosive gas atmospheres are continuously present or exist for extended periods, typically exceeding 1000 hours per year.
Zone 1 - Locations where explosive gas atmospheres may occur during normal operation, generally 10-1000 occurrences per year.
Zone 2 - Under normal operating conditions, explosive gas atmospheres are not likely to occur or, if they do, they are only occasional and of short duration, generally less than 10 hours per year.

Currently, there is no unified platform for querying the qualifications certificates for installation, maintenance, and repair of explosion-proof electrical equipment from various certification bodies; they are all checked on their respective websites.
You can verify the authenticity of the qualification certificates for the installation, maintenance, and repair of explosion-proof electrical equipment by checking the certificate number on the issuing authority's website. Each qualification certificate for the installation, maintenance, and repair of explosion-proof electrical equipment has a unique certificate number, which is the key information for verifying the certificate's authenticity.
Certification for Installation, Maintenance, and Inspection of Explosion-Proof Electrical Equipment is one of the qualifications for companies in the explosion-proof electrical construction industry. It signifies that the company and its construction personnel have completed training in explosion-proof electrical construction safety knowledge and have mastered the relevant technologies and knowledge. This certification is fundamental for conducting explosion-proof electrical construction work. Therefore, verifying the authenticity of the certificate is crucial for ensuring construction quality and safety.
