ATEX Certification – ATEX Directive 2014/34/EU

Get Your Products to Eu Markets Faster with ATEX Certification

Certain industrial environments pose an increased risk of fire and explosion, due to the use of flammable gases, vapors or combustible dusts. These potentially hazardous environments, also known as “Ex areas” (short for explosive areas), are found in a range of industries, including oil and gas refineries and distribution facilities, chemical processing plants, grain and agricultural handling, processing and storage facilities, underground mines, and even hospital operating environments. The term ‘ATEX’ comes from the French name for the 2003 directive: les appareils et les systèmes de protection destinés à être utilisés en ATmosphères EXplosibles (explosive atmospheres). It covers both machinery or equipment that is destined to be used in these environments, and rules for managing the general environment in such workplaces.

Equipment used in these hazardous environments must therefore be expressly designed to minimize such risks, and manufacturers of electrical, non-electrical, electronic, mechanical equipment and systems must ensure that their products meet the enhanced requirements of applicable regulations and standards.

In the European Union (EU), compliance with the essential requirements of EU Directive 2014/34/EU, also known as the ATEX Directive, is required for equipment used in potentially explosive environments. In other markets, the voluntary IECEx Equipment Certification Scheme can facilitate acceptance of such equipment. Although similar in scope and intent, the ATEX Directive and the IECEx Scheme encompass different requirements and utilize different assessment approaches, complicating the regulatory approval process for equipment manufacturers.

Under the provisions of the ATEX Directive, evidence of compliance is generally demonstrated by the issuance of a manufacturer’s, or supplier’s, Declaration of Conformity, based on an independent technical assessment. Special requirements apply to electrical products intended for use in high risk areas. The task of demonstrating compliance with the ATEX Directive rests with the party responsible for introducing a product into the EU marketplace. The responsible party is typically the product manufacturer, but it may also be an importer or wholesaler.

Examples of actions and reactions that can serve as an ignition source:

• Electric sparks – A poor quality component or electrical connection can fail, inadvertently producing an electric spark that can ignite gases or nearby materials.
• High operating temperature – Depending upon the particular potentially explosive atmosphere content, hot surfaces on equipment could cause auto ignition. Process system heating effects by ‘work done’ i.e. pumping systems, must also be considered as these can elevate the ‘product’ above its flashpoint.
• Electrostatic discharge – Some normal equipment operations can generate static electricity, which can serve as an ignition source at certain levels.
• Friction sparks – Equipment operation may also involve repeated contact between materials, resulting in friction that can produce heated sparks

ATEX Compliance and Safety Requirements

If you manufacture or sell equipment and systems of this nature, TÜV SÜD can ensure you conform to the relevant ATEX Directives and entitle you to feature the CE mark.

Equipment, components and protective systems in a potentially explosive environment can only be placed on the market if essential health and safety requirements according to the ATEX Directive 2014/34/EU have been met, and the required conformity assessment procedures for your category of equipment have been successfully completed.

The following products are affected by the ATEX Directive 2014/34/EU:

• Equipment: Machinery, electrical equipment, fixtures, control equipment, and parts
• Protection Systems: Explosion suppression systems and relief systems and others
• Components: Components required for the safe operation of equipment and protective systems

We'll work with you to:

• Define ATEX zones in the workplace
• Complete an explosion protection document (EPD)
• Produce certification of equipment and assemblies
• Conduct ignition source analysis (including electrostatics)
• Determine safety data - for both operating companies and manufacturing companies

Our sub-services include:

• Explosion protection concepts and EPD
• Definition of zoning (ATEX, NFPA)
• Ignition source analysis
• Certification of equipment
• Determination of safety data
• Design of venting systems
• Assessment of old equipment - assessment of equipment placed on the market before July 2003

Benefits of ATEX Certification to Your Business

• Protection - Conducting ATEX 2014/34/EU assessments means your product or working environment is much less likely to undergo an explosion.

• Safety - A clear benefit of ATEX 2014/34/EU certification is that you minimize the risk to life or property caused by explosions.
• ATEX Certification – TÜV SÜD Industrial Technical Inspections Services can assist customers with the certification of equipment, components, protective systems and entire processing plants for all equipment groups and categories
• Classification - TÜV SÜD experts can assist manufacturers in the process of classifying their products to equipment type, category and other classification requirements found within the ATEX Directive 2014/34/EU Directive and other relevant standards such as IECEx Certification Scheme.
• Validation - As a Notified Body, TÜV SÜD and its partners can validate your product’s design and issue the required Type Approval to Annex III or a single approval to Annex IX of the Directive.
