The IECEx is an international certification system that covers equipment that operates in any environment where there is a risk of explosion. Published last year, ISO/IEC 80079-36 and ISO/IEC 80079-37 meant that, for the first time, non-electrical equipment for use in explosive atmospheres can achieve IECEx certification.

IEC 80079-36 covers the basic method and requirements for non-electrical equipment. IEC 80079-37 covers non-electrical equipment for specific types of protection. These are:

• 鈥榗onstructional safety鈥� (鈥渃鈥�)
• 鈥榗ontrol of ignition sources鈥� (鈥渂鈥�)
• 鈥榣iquid immersion鈥� (鈥渒鈥�)

Non-electrical equipment meeting the requirements of EN ISO 80079-36:2016 is marked with the Ex-marking code 鈥渉鈥�. Non-electrical equipment meeting the requirements of EN ISO 80079-37:2016 supplemental to those of EN ISO 80079-36:2016 is also marked with the Ex-marking code 鈥渉鈥�. The description of the type of protection, such as 鈥渃鈥� for constructional safety, is provided in the instructions manual of the equipment.

The compliance route follows the same process that governs IECEx approval of electrical equipment. As well as a product assessment and the issuing of an IECEx Certificate of Conformity, a Quality Audit Report (IECEx QAR) is also required to demonstrate that the manufacturing process of such equipment is in line with the product approval. This means that multiple units can be manufactured without 100% inspection being required.

The IECEx operates alongside existing certification schemes such as the European ATEX product directive for hazardous location equipment. ATEX non-electrical certification has always been part of ATEX Certification but certification could be 鈥榮elf-certified鈥� (with the file lodged with a Notified Body). This meant that there was little control as to the depth and accuracy of the assessment.

For all ATEX Categories (zones) the manufacturer of the equipment must now conduct a risk assessment and create a 鈥楾echnical File鈥� to comply with the Directive and to then be able to CE Mark the equipment.

A Notified Body must do the assessment for Category 1. The manufacturer may do the assessment themselves for Category 2 but must 鈥榣odge鈥� the Technical File with a Notified Body. For Category 3 the manufacturer may hold the Technical File internally.

Under IECEx, no self-certification is permitted with Test and Certification always conducted by an IECEx Certified Body.

As a Notified Body (NB) for the ATEX Directive, an IECEx Testing Laboratory (ExTL) and an IECEx Certification Body (ExCB), 日本av无码is able to issue IECEx non-electrical certificates. Qualified in both ATEX and IECEx systems, our engaged experts can help construct a single test certification programme that accommodates any additional testing.
