This is a reference list of certification standards that can be useful for hazardous locations design.
Please note that certain standards in this list may no longer be current. They are listed here for reference, and to support those applications that still require certification to the older standards.
Generally, standards must be purchased. This might be done via their issuing organization, or by various distributors and resellers.
As web sites change frequently, we are not able to provide links. For assistance in identifying or locating standards relevant to your application, please contact us.
