Pressure sensors and electronic devices may only be used in hazardous areas if they have been tested and approved by a recognised authority in terms of their explosion protection features. So far, this was mostly carried out by a national institution which, after successful testing, issued a national declaration of conformity.<\/strong><\/p>\n

Having to obtain a national certification for each country meant significant additional costs for the users who wanted to sell or operate their machines internationally, as well as for the manufacturers of certified electronic devices. The first step towards international simplification in terms of declarations of conformity and certifications was the introduction of the EU directive 94\/9\/EC \u201cATEX\u201d in 1994.<\/p>\n

This directive applies for the entire EU economic area and allows a cross-border purchase and use of certified explosion-proof devices within the EU, without having to additionally obtain a national approval or declaration of conformity. Since the introduction of \u201cIECEx Certificates of Conformity\u201d (IECEx CoC) in 2003, it has become even easier for users and manufacturers to obtain an international certification. When generating an IECEx declaration of conformity, three documents are set up:<\/p>\n

    \n
  1. International test report Product Type Testing (Product assessment and test report ExTR)<\/li>\n
  2. International quality audit report Factory servicing and evaluation of the quality assurance systems (Quality Assessment Report, QAR)<\/li>\n
  3. International certificate of conformity (IECEx CoC)<\/li>\n<\/ol>\n

    When using pressure sensors in hazardous areas, the certification of conformity per IEC 60079 (\u201celectrical equipment for hazardous gas atmospheres\u201d) and IEC 61241 (\u201celectrical devices for hazardous dust atmospheres\u201d) is required. An advantage of using instruments with IECEx CoC is that, based on the declaration of conformity and the documents ExTR and QAR, the 32 participating member states<\/a> can obtain the desired national declaration of conformity in the course of a \u201cfast-track\u201d procedure within a few months.<\/p>\n

    The grand vision of the IECEx system is the complete recognition of the IECEx CoC in all member states, thus creating a single internationally valid declaration of conformity for explosion-proof devices and pressure sensors. However, so far only Australia has recognised the IECEx certificate of conformity, with restrictions, as a replacement for a national Australian certificate of conformity. WIKA offers comprehensive solutions for the use of pressure sensors in hazardous areas.<\/p>\n
