Explosion Protection Certification for Equipment


Explosion Protection Certification for your Equipment or Products

If you manufacture or sell electrical and/or mechanical equipment, components or protective systems for use in – or in conjunction with – potentially explosive atmospheres in the European Union (EU) or worldwide, your products need to comply to relevant standards and/or directives also to meet certification requirements.

TÜV Rheinland, a globally accepted Notified Body and Ex Test Laboratory and Certification Body, tests and certifies your product in compliance with regional applicable standards.

Beyond the equipment testing and certification TÜV Rheinland offers product manufacturers factory inspection and field evaluation as required by the worldwide applicable explosion protection standards or directives.

Worldwide different certification schemes defining safety levels of products for use in hazardous areas exist, like for example ATEX for Europe, Inmetro for Brazil, Hazloc for the US, TIIS for Japan etc.. Although safety is the driving force of all schemes, their product scope, classification of application areas and operational requirements differ.

Our TÜV Rheinland experts can support you to determine which certification scheme is more suitable for your equipment and covers EU and/or global explosion protection standard and directive requirements.

ATEX95 (ATmosphère Explosive) – Europe

The ATEX Directive applies to all  electrical and mechanical equipment, components, protective systems, and specified safety-, control- and regulating devices intended for use in or in conjunction with potentially explosive atmospheres and made or sold within the European Union. This includes electrical and mechanical equipment and protective systems for use on  surface or mining areas . Ultimately, the ATEX95 (94/9/EC) Directive pertains to all equipment, protective systems, safety devices, controlling devices, regulating devices, and components (defined essential to the safe functioning of equipment).
Compliance with the ATEX95 Directive has been mandatory since July 1, 2003. Manufacturers of equipment falling under the scope of the ATEX Directive are responsible for meeting the general requirements of Annex II by applying all relevant occupational health and safety standards based on the design and “protection methods” of the product.

ATEX Certification forms a part of the CE Marking Requirements, which subjects all products under the scope of the ATEX Directive to CE marking. In addition, manufacturers must meet specific responsibilities prior to introducing equipment to the European market.

If you are interested in TÜV Rheinland’s ATEX Certification services, you may also be interested in these testing services:

  • Factory Inspection

IECEx –  worldwide / Australia and New Zealand
International Electrotechnical Commission for Certification to Standards relating to Equipment for use in Explosive Athmospheres)

While ATEX95 certification enables trade within Europe, IECEx verifies compliance of electrical equipment for explosive atmospheres in order to facilitate international trade in equipment and services while maintaining the required level of safety. It is primarily used to grant access to the markets in Australia and New Zealand. Beyond that all participating Ex Test Laboratories share and accept their Ex Test Reports, therewith just the “National Differences” need to be tested additionally.

IECEx is directly referenced to IEC standards relating to equipment for use in explosive atmospheres.

If you are interested in TÜV Rheinland’s IECEx Certification services, please refer to the following website:  www.iecex.com

Hazloc (Hazardous Locations) – USA

Hazloc certification primarily concerns North America. The acronym stands for Hazardous (Classified) Locations, referring to any industry that processes, uses or manufactures materials that may give rise to a flammable atmosphere (gas, mist, liquid, dusts or even small fibers). These atmospheres are potentially explosive and therefore qualify as a hazardous location.

The US National Electrical Code (NEC) is the primary source of reference for hazardous locations within the USA. Although the terms are defined by the United States, they have a lot in common with the EU and IEC requirements. US participation in writing IECEx procedures and IEC standards has also meant that US standards are slowly moving towards harmonization with the IEC (and EN) standards. However, for now, significant differences remain between equipment standards and definitions of hazardous areas.

Hazloc certification includes product testing and assessment as well as factory inspection.

INMETRO (National Institute of Metrology Standardization and Industrial Quality) - Brazil

In Brazil, certification bodies must be accredited by INMETRO.

INMETRO certification is mandatory for electrical products that are intended to be placed onto the Brazilian market, according to the rule 179.

The equipment testing and certification is originally based on IEC standards, which are consequently transferred to Brazilian ABNT NBR standards.

TIIS (Technology Institution of Industrial Safety) - Japan
The Explosion Protection certification in Japan is an explosion-proof certification  done by the Technology Institute of Industrial Safety (TIIS).

Based on the declaration of TÜV Rheinland as a “Designated Foreign Inspection Body” for Explosion-Proof Services in Japan, manufacturers of explosion protection related products can now utilize the TÜV Rheinland test report in order to obtain approval for export to Japan.

The Japanese TIIS takes the TÜV Rheinland test report over as a basis. The “National Differences” need to be covered additionally. Thanks to this agreement, customers now have the advantage of being able to apply for two approvals, European ATEX and Japanese Explosion-Proof Certification, with a single test format.

Conformity Certification of Explosion Proof - China

TÜV Rheinland do have MOU’s (Memorandum of Understanding) with the Chinese Test and Certification Bodies NEPSI, CQST and PCEC.

On the basis of TÜV Rheinland’s ATEX- and/or IECEx Test Reports a Chinese Certificate of Explosion Proof can be derived.
TÜV Rheinland assists in this procedure, according to the “One Stop Certification” idea.

Further Ex-Certification Schemes worldwide – Korea / Russia / others

TÜV Rheinland has further contacts, agreements to Ex-Test and Certification Bodies worldwide.

Therewith we can assist in gathering of further certifications like for Russia (GOT-R) and Korea.
