Many companies develop products that need to operate in explosive atmospheres - areas where flammable liquids, vapors, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion.
Increased industrial automation means that more electronic products operate in such environments, therefore requiring certification to ensure that they will not cause an explosion during normal operation.
In the UK, equipment has traditionally been certified to the ATEX standard, but increasingly companies are choosing IECEx testing because it enables one laboratory to carry out core testing that will be accepted by the 31 countries which are members of the scheme. This not only makes design and development simpler, with engineers designing for just one standard, but also dramatically cuts the cost, time and paperwork involved in selling products internationally.
In addition to helping secure international acceptance for a product, a well-planned approach to testing and the right test house means that you can complete IECEx testing alongside CE certification. My company is just one of many that have seen the benefits of ATEX: there are now 10,000 IECEx-certified products in use, and the number of certificates issued has increased six-fold in the last four years (reaching 1,500 in 2009). More information about IECEx testing can be found on the organisation's website, or email me and I'll send you a copy of the white paper I've recently written about Ex testing.
