Ex防爆Certificate Application Documents for Pedestrian Robot, Shenzhen ZhongNuo Inspection

Shenzhen ZhongNuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal mine safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion prevention for electrical equipment.
The outer shell is capable of withstanding explosive mixtures entering the shell through the joint surfaces or structural gaps, and exploding internally without causing damage.
And cause ignition of an explosive gas atmosphere formed by one or more gases or vapors.
The explosion-proof casing must have both explosion-proof and explosion-resistant properties. Generally, the casings of products designed for explosion-proofing are rather bulky.
Products and equipment suitable for fixed installation and use.
Combustible gas-tight junction width, gap, and roughness are the three key elements in explosion-proof housing design.
Design requirements for explosion-proof elements vary depending on the different explosive gas environments in mining Class I, non-mining Class IIA, IIB, and IIC.
Please refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.
Zhenuo Testing has long been focused on the design, testing, and certification services for explosion-proof products.
We have a dedicated explosion-proof technology team in the explosion-proof field, well-versed in explosion-proof standard requirements.
Offer explosion-proof housing design, drafting, modification guidance, certification consultation, and more.

Certification standards for explosion-proof equipment used in environments with explosive gas:
GB/T 3836.1-2021 Explosive Atmospheres Part 1: Equipment General Requirements
GB/T 3836.2-2021 Explosive Atmospheres – Part 2: Equipment protected by explosion-proof enclosures “d”
GB/T 3836.3-2021 Explosive Atmospheres Part 3: Equipment protected by an increased safety "e" type
GB/T 3836.4-2021 Explosive Atmospheres, Part 4: Equipment protected by intrinsic safety "i"
GB/T 3836.5-2021 Explosive Atmospheres Part 5: Equipment protected by positive pressure enclosure "p"
GB/T 3836.6-2017 Part 6: Equipment protected by liquid immersion type “o” for explosive atmospheres
GB/T 3836.7-2017 Explosive Atmospheres Part 7: Equipment protected by sand filling type “q”
GB/T 3836.8-2021 Explosive Atmospheres, Part 8: Equipment protected by "n" type protection
GB/T 3836.9-2021 Explosive Atmospheres, Part 9: Equipment protected by “m” type enclosures

In hazardous areas where flammable and explosive substances are present, the site must be divided into explosion-proof zones based on the frequency and duration of the substances' appearance. This is to ensure the correct selection and installation of electrical equipment in these hazardous areas, aiming for safe operation. The division is according to explosion-proof standards.
Explosive gas environments are classified into Zones 0, 1, and 2. Zone 0 is hazardous, indicating that explosive gas mixtures are present for extended periods under normal conditions, such as within oil and gas transmission pipelines. Correspondingly, the explosion-proof areas for explosive dust environments are classified into Zones 20, 21, and 22.
Dividing explosion-proof zones is crucial for selecting the appropriate explosion-proof electrical equipment. For instance, Zone 0 requires intrinsically safe ia electrical equipment, while Zone 1 allows for both ia and ib intrinsically safe equipment, offering a wider range of options.

The explosion-proof certificate is a certification model for products outside the explosion-proof 3C catalog.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification list, which is a mandatory product certification. Products on the list require an explosion-proof 3C certification, following the "product testing + factory audit" model. For a detailed explosion-proof 3C certification list, please refer to the relevant information on our website. Explosion-proof products not on the list can opt for a certification of conformity, obtainable simply by passing the product testing.
The general process for obtaining a防爆 certification includes: submitting relevant product documents, conducting product testing, and upon passing the test, issuing the防爆 certification. During the application process, ensure your product meets the relevant explosion-proof standards and requirements.
If you're not familiar with explosion-proof standards and certification requirements, no worries. Shenzhen ZhongNuo Testing Technology Co., Ltd. offers explosion-proof design and rectification services, as well as certification agency services for intrinsic safety, flameproof, oil-tight, and positive pressure types. We help businesses conveniently obtain explosion-proof certificates.
