Genral practical guide for implementation ATEX quality assurance system for production process

Introduction and generalities

  • The purpose of this article is to give general practical gide to the producers of explosion-proof products the QMS consultants relevant to it;

  • This guide includes only specific requirements of EN ISO/IEC 80079-0:2020, excluding ISO 9001 requirements;

  • Therefor this guide maybe useful only for the manufacturers which have already implemented ISO 9001 requirements and will enable them to add or involve the needed information and documents relevant to specific requirements of EN ISO/IEC 80079-34:2020 to their existing quality management system documentation;

  • ConformEx, based on its adherence to its policies (M-M-02) and also restrictions (M-M-03), never, under any circumstances, accepts or provides any requests for consulting services for the production of quality management systems for explosion-proof equipment.

4.1 Understanding the organization and its context: 

  • to add the subject of "compliance Ex designed and produced product with its relevant EU type examination certificate and relevant technical documentation", as one of the internal and/or external issues in the analysis of the issues affect the organization ability to achieve the intended result(s) of its quality management system.

    • e.g.1 Risk of potential harm to customers due to the installation of non-conforming products manufactured by the company on their sites and the occurrence of an explosion and subsequent legal actions may be raised from users of the product, as an external issue.

    • e.g.2. Risk resulting from a negative financial balance in explosion-proof parts production projects, due to the significant costs of production and obtaining ATEX certification, in the face of a small number of explosion-proof product customers, as an internal issue.

  • to specify the affect(s) on organization, including opportunties and threats; and

  • to define appropriate actions to reduce or eliminate the effects of threats and/or exploiting opportunities.

Obligation to develop an independent procedure or inclusion in existing ISO 9001 system procedure: No

Obligation How to record the outputs of the implementation of this requirement: inclusion or add to the existing records of ISO 9001  

4.2 Understanding the needs and expectations of interested parties: without specific requirements additional to ISO 9001

However this clause of standard does not include specific requirements of EN ISO/IEC 80079-34, but the organization should add the interested parties which are relevant to its produced explosion-proof products and should define their requirements. e.g. end user of explosion-proof product.

4.3 Determining the scope of the quality management system:  without specific requirements additional to ISO 9001 

However this clause of standard does not include specific requirements of EN ISO/IEC 80079-34, but the organization should check of its defined scope for ISO 9001 system covers the production of explosion-proof products, and if there was any failure or conflict, the scope of QMS should be modified. 

4.4 Quality management system and its processes:

an executive method including a control checklist for "ensuring that the Ex Product conforms to the type described in the EU type examination certificate and the relevant technical documentation" shall be included in one of the procedures or other documents of the quality management system or as an independent document of the QMS.

the checkpoints for the above-mentioned control consist two groups, including:

  • general points; and

  • control points relevant to the specific protection type(s) of the equipment.

the methods of control consist:

  • visual check of the equipment against the relevant information included in ATEX certificate and product technical file; and

  • checking technical documentation and manufacturer's documentation which are exclusively relevant to the product.

a sample for template of the control checklist is downloadable from here.
