About the ATEX directive

If you manufacture electrical equipment used in hazardous locations and intend to market your products in the European Union, your equipment must comply with the ATEX directive. Also known as European Directive 2014/34/EU, the ATEX directive ensures the free movement of goods throughout the European Union by harmonizing compliance procedures.

The ATEX requirements
  • The ATEX directive requires the following major elements to be met in order to apply the ATEX marking:
  • The CE mark – The CE mark is a self-declaration marking indicating that your equipment conforms to applicable technical provisions and ATEX requirements and other directives.
  • Essential health and safety requirements – Annex II of the ATEX directive, requires that you establish principles of integrated explosion safety from all electrical and non-electrical ignition sources. You can demonstrate compliance to these requirements by following the harmonized European standard series EN 60079.
  • EC Type Examination Certificate – For Category 1 (electrical and mechanical) and Category 2 (electrical) equipment, a Notified Body will need to verify that your equipment has met the relevant applicable provisions of the ATEX directive in order to receive an EC Type Examination Certificate. For Category 3 equipment, an EC Type Examination Certificate is not required, however, manufacturers must ensure that your products comply with ATEX by following the appropriate conformity route.
  • Quality Assessment – The facility(s) producing your equipment must undergo a Quality Assessment of EN ISO/IEC 80079-34 which will result in a Notified Body issuing you a Quality Assurance Notification (QAN).


The CE marking is a key indicator (but not proof) of a product’s compliance with European Union (EU) health, safety and environmental protection directives and regulations.

  • If your product comes under the scope of a directive requiring CE marking you must ensure the product complies with the applicable requirements and affix the CE mark before placing it in the market in the European Economic Area (EEA) (see “Countries In Which The CE Marking Is Required” below for a description of the countries that are included in the EEA). This is equally valid if your product is manufactured outside the EEA. Second hand products from outside the EEA that are placed in the EEA market for the first time, also require CE marking.

  • Often the CE marking is described as a trade passport because it enables the free movement of products within the European market. According to EU legislation, the EU Member States are not allowed to restrict the placing on the market of CE marked products, unless such measures can be justified on the basis of evidence of the non-compliance of the product. CE marking does not indicate that a product was made in the European Union. The CE mark also is not a quality mark.

SEPCo Lifted Equipment(OPS0055 Appendix G)

To prevent incidents associated with lifting and hoisting, this standard establishes Shell Exploration and Production Company’s (SEPCo) requirements for the:

  • operation, maintenance, testing, certification, inspection, and design of lifting equipment
  • the competency and qualifications of individuals involved with these operations.

This certification requires a Professional Engineering stamp and approval
