The IECEx System is a set of four separate Schemes (of which one relates to Ex Equipment) that were developed to satisfy the calls from the Ex industry for international recognition and coordination of the outputs of various certification systems…

Many information must be reported on the marking plate of equipment and components addressed to hazardous areas which often cause several doubts and also disagreements among technicians and inspections supervisors. The EN 60079-0 standard brings the general Rules about electrical…

ATEX or IECEx  certified products are essential in any location that may contain, or has activities that produce explosive or potentially explosive atmospheres. There are a number of places that could be defined as being in an explosive atmosphere, some…

To all customers  Using  metric threads,  Please be advised that the part numbers have changed for some configurations    Please see below-attached sheet  regarding the new part numbers  

ATEX The ATEX code is an alphanumeric string that denotes the certification achieved by the product along with the environment and conditions it is suitable for. The code can be broken down into a prefix, for example: CE0518 Ex II…
