However, the UK government has indefinitely extended recognition of CE-marked products in numerous categories, including Ex equipment. As of 2025 ATEX certification can still be used to access the Mid Atlantic market. Firms intending to release equipment into the UK should keep an eye on regulatory developments, since the transition period deadline may change.<\/p>\n<\/div>\n<p><!-- H2-6 --><\/p>\n<h2 style=\"margin: 48px 0 16px; padding-bottom: 10px; border-bottom: 2px solid #183090;\">Can a Product Carry Both ATEX and IECEx Certification?<\/h2>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-2865\" src=\"https:\/\/gqlamp.com\/wp-content\/uploads\/2026\/03\/1-29.png\" alt=\"Can a Product Carry Both ATEX and IECEx Certification?\" width=\"512\" height=\"512\" srcset=\"https:\/\/gqlamp.com\/wp-content\/uploads\/2026\/03\/1-29.png 512w, https:\/\/gqlamp.com\/wp-content\/uploads\/2026\/03\/1-29-300x300.png 300w, https:\/\/gqlamp.com\/wp-content\/uploads\/2026\/03\/1-29-150x150.png 150w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/p>\n<p>Yes &#8211; and for manufacturers providing a global reach dual Dangun Iwvo is the expected norm.

OSHA&#8217;s expectation is that equipment being installed in USA location uses has certification from an NRTL, e.g. UL, CSA, FM or Intertek, listed equipment. iecex test reports are often used as supporting evidence for an NRTL application, providing the possibility to shorten the scope of testing at this time.<\/div>\n<\/details>\n<\/div>\n<div style=\"margin: 16px 0;\">\n<h3 style=\"margin: 0 0 4px;\">What is the US equivalent of ATEX certification?<\/h3>\n<details style=\"border: 1px solid #e0e0e0;\">\n<summary style=\"padding: 12px 20px; cursor: pointer; background: #f5f5f5; color: #6b7280;\">View Answer<\/summary>\n<div style=\"padding: 12px 20px 16px;\">There is no role equivalente US &#8216;Atex&#8217;. Equipment certification for US location equipment is through NRTLs (UL, CSA, FM, Intertek) against ANSI\/UL or ANSI\/ISA standards under the NEC Article 500\/505. In the field of lighting, UL 844 is the document number. With the common function of assure the safety of the equipment, Atex and USA certification shares the same thing, but they are two legally different structures, standards and certification bodiess.<\/div>\n<\/details>\n<\/div>\n<div style=\"margin: 16px 0;\">\n<h3 style=\"margin: 0 0 4px;\">Does OSHA recognize ATEX?<\/h3>\n<details style=\"border: 1px solid #e0e0e0;\">\n<summary style=\"padding: 12px 20px; cursor: pointer; background: #f5f5f5; color: #6b7280;\">View Answer<\/summary>\n<div style=\"padding: 12px 20px 16px;\">No. OSHA does not recognize ATEX as a valid certification for equipment installed in US hazardous locations. Under 29 CFR 1910.307, OSHA requires that equipment be listed or labeled by a Nationally Recognized Testing Laboratory (NRTL). ATEX certification demonstrates compliance with EU directives, which operate under a fundamentally different legal and technical framework from the US system governed by OSHA regulations and the National Electrical Code (NEC Articles 500\/505). Equipment destined for the US market must carry UL, CSA, FM, or Intertek certification against the applicable ANSI\/UL standards \u2014 for example, UL 844 for hazardous location luminaires.<\/div>\n<\/details>\n<\/div>\n<div style=\"margin: 16px 0;\">\n<h3 style=\"margin: 0 0 4px;\">Is IECEx accepted in Europe?<\/h3>\n<details style=\"border: 1px solid #e0e0e0;\">\n<summary style=\"padding: 12px 20px; cursor: pointer; background: #f5f5f5; color: #6b7280;\">View Answer<\/summary>\n<div style=\"padding: 12px 20px 16px;\">certification alone does not give access to the EU market; the atex certification with CE mark is mandatory. iecex test reports are generally accepted as supporting evidence and many EU Notified Bodies operate as IECEx ExCBs these days, so it makes sense to run both certifications along one certification body&#8217;s track.<\/div>\n<\/details>\n<\/div>\n<div style=\"margin: 16px 0;\">\n<h3 style=\"margin: 0 0 4px;\">What industry sectors require ATEX or IECEx certification?<\/h3>\n<details style=\"border: 1px solid #e0e0e0;\">\n<summary style=\"padding: 12px 20px; cursor: pointer; background: #f5f5f5; color: #6b7280;\">View Answer<\/summary>\n<div style=\"padding: 12px 20px 16px;\">Any industry which has potential for explosive atmospheres to be formed would need certified equipment. Oil and gas operations (upstream and downstream) are the most obvious, but the requirement extends to chemical processing, pharmaceutical manufacturing, grain handling, mining, paint booths, and wastewater treatment facilities. The certification is for all electrical and non-electrical equipment used in classified hazardous areas in any of those industries.<\/div>\n<\/details>\n<\/div>\n<div style=\"margin: 16px 0;\">\n<h3 style=\"margin: 0 0 4px;\">How long does ATEX or IECEx certification typically take?<\/h3>\n<details style=\"border: 1px solid #e0e0e0;\">\n<summary style=\"padding: 12px 20px; cursor: pointer; background: #f5f5f5; color: #6b7280;\">View Answer<\/summary>\n<div style=\"padding: 12px 20px 16px;\">For an item that already satisfies the relevant IEC 60079 standards the baseline certification is around 12-16 weeks. Practically however, most certifications take 6 months or more as modifications to the design are usually needed; many of the main certification bodiess have lead times of 12\u201326 weeks before the work can even start on Ex work. You can plan for around 9-12 months from start of the project to certificate issue for first time certification applicants.<\/div>\n<\/details>\n<\/div>\n<div style=\"margin: 16px 0;\">\n<h3 style=\"margin: 0 0 4px;\">Can ATEX certification be converted to IECEx?<\/h3>\n<details style=\"border: 1px solid #e0e0e0;\">\n<summary style=\"padding: 12px 20px; cursor: pointer; background: #f5f5f5; color: #6b7280;\">View Answer<\/summary>\n<div style=\"padding: 12px 20px 16px;\">Not directly; certification documentation for Atex can support in an IECEx application but the iecex scheme therefore needed has its own certificate of conformity, iecex test report and Quality Assessment Report. An Atex test report can reduce the certification scope if it has been done to test to equivalent IEC 60079 standards, but it is the IECEx ExCB which will determine what extra work needs to be done.
