ATEX Harmonised Standard EN 1127 – 1

The ATEX harmonised standard EN 1127-1 – Explosive atmospheres – Explosion prevention and protection – Part 1: Basic concepts and methodology was updated in 2019 (EN 1127-1:2019). The old version from 2011 (EN 1127-1:2011) will be withdrawn from the Official Journal of the European Union on February 1, 2022.

EN 1127-1 is one of the most used harmonized standards to ensure that a product does not contain any unmitigated ignition sources and is a vital part used to cover the essential health and safety requirements for ATEX equipment.

If you require more information about the implications of the withdrawal of EN 1127-1:2011 for your product and how to prepare and apply for the revised standard, please contact us at:

About harmonised standards (Copied from the ATEX Guideline):

The presumption of conformity of products to is conferred by the use of European harmonised standards the reference of which is published in the Official Journal of the European Union (OJEU).

The European Standardisation Organisations (CEN, CENELEC and ETSI) and their specific Technical Committees, as well as other sectoral interested parties (national experts, notified bodies, industry, etc.) are involved in the development of European standards. These standards are commonly the preferred option for demonstrating compliance once they become available as harmonised standards.

Voluntary harmonised standards are the only documents the application of which provides for presumption of conformity in the sense of the ATEX Product Directive. Manufacturers may also decide to use other existing European, international or national standards and/or technical specifications regarded as important, relevant or useful to cover the applicable essential health and safety requirements of the Directive, together with additional controls addressing those other requirements not already covered.

European standards are amended and updated on a regular basis and in response to new technical knowledge, to reflect the available “state of the art”. During the process of updating, a manufacturer may continue to use a current harmonised standard to claim full compliance with the Directive, until a new harmonised standard replaces (supersedes) the previous one, at the end of the established transition period, as usually set.
