The IECEx is an international certification system that covers equipment that operates in any environment where there is a risk of explosion. 去年出版的, ISO/IEC 80079-36 and ISO/IEC 80079-37 meant that, 第一次, non-electrical equipment for use in explosive atmospheres can achieve IECEx认证.
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. 这些都是:
- ‘constructional safety’ (“c”)
- ‘control of ignition sources’ (“b”)
- ‘liquid immersion’ (“k”)
Non-electrical equipment meeting the requirements of EN ISO 80079-36:2016 is marked with the Ex-marking code “h”. 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 “h”. The description of the type of protection, such as “c” 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 欧洲an ATEX product directive for hazardous location equipment. ATEX non-electrical certification has always been part of ATEX认证 but certification could be ‘self-certified’ (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 ‘Technical File’ 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 ‘lodge’ the Technical File with a Notified Body. For Category 3 the manufacturer may hold the Technical File internally.
在IECEx, no self-certification is permitted with Test and 认证 always conducted by an IECEx Certified Body.
As a Notified Body (NB) for the ATEX Directive, an IECEx 测试 Laboratory (ExTL) and an IECEx 认证 Body (ExCB), im体育APP 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.
