IECEx ile ilgili Kuzey Amerika’daki geçişi anlatan güzel bir makaleye aşağıdaki linkten erişebilirsiniz. Ancak okurken benim için en can alıcı kısım şurası oldu: While the IECEx system is still fairly new, with the majority of certificates being issued in the last ten years or so, it has completely changed how manufacturers approach certification for multiple countries. As the system continues to evolve, it is rapidly becoming the dominant certification system for all Ex products. The IECEx is working diligently to remove any nontariff trade barriers and to have countries identify the system as meeting all their national requirements for Ex products By Paul T Kelly, Thorsten Arnhold, and Marty Cole
