Where to apply for explosion-proof certification for positive pressure electromagnetic heaters? Zhongnuo Inspection

Shenzhen ZhongNuo Testing Technology Co., Ltd. is based in South China, specializing in explosion-proof certification and coal mine safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
Intrinsically safe certification is widely applied to low-power, low-energy instruments, handheld terminal products, and more. These devices produce relatively low energy, making it easy to control them within a safe range through technical means, thereby meeting intrinsic safety requirements. For example, temperature vibration sensors, remote transmitters, monitoring devices, Bluetooth beacons, walkie-talkies, and other products are all candidates for intrinsic safety certification.

How to apply for an explosion-proof marking certification?
The explosion-proof marking can be considered as an identifier for explosion-proof equipment. It allows users and installers to quickly understand the explosion-proof type of the product, along with corresponding gas/dust types and temperature classes, etc. This helps to prevent situations like installing a gas explosion-proof product in a dust-prone area, or an "n" type product in an explosion-proof zone of category 1, ensuring that explosion-proof products are properly matched with hazardous locations.

Is " intrinsic safety certification" the same as "explosion-proof certification?" What are the differences between them?
Explosion-proof certification refers to a safety certification for equipment and products used in explosive hazardous areas.
To meet the explosion-proof certification standards, certain measures must be taken to achieve it, which we refer to as explosion-proof protection types.
Common explosion-proof protection types include intrinsic safety, flameproof, positive pressure, and increased safety, etc.
Clearly, intrinsic safety is just one type of explosion-proof protection.
Different explosion-proof protection types have varying design requirements for the product.
intrinsic safety is a type of explosion-proof protection that limits electrical energy, ensuring that even in the event of a fault, the energy produced is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements for electrical equipment include limitations on current, voltage, capacitance, inductance, etc., and are generally suitable for low-power equipment.
Additionally, specific requirements are outlined for the power supply method, casing material, and wireless transmission of explosion-proof equipment.
As a third-party consulting firm specializing in explosion-proof certification for many years, China Nu Inspection boasts dedicated engineers in intrinsically safe circuit and structural design. We offer technical consultation on explosion-proof circuit design, drafting, and rectification. We have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic classifications.

What standards are used for testing and certification of explosion-proof electrical equipment?
Firstly, it's important to distinguish whether the product requires certification or if the on-site facility needs explosion-proof electrical testing.
On-site explosion-proof electrical testing is conducted in accordance with the provisions of AO3009-2007 standard, requiring at least one routine testing for electrical equipment in use every 3 years.
And provide a testing report. This is mainly for the users of explosion-proof equipment.
Product testing and certification generally refers to conducting relevant tests on new products entering the market in accordance with the GB/T 3836 series standards.
The process of obtaining the explosion-proof certification. This requires providing product design drawings, manuals, and other documentation.
Generally, it is aimed at the manufacturer or supplier of the equipment.
