MARKING OF CABLE GLANDS FOR HAZARDOUS AREAS
Cable Glands are classified as being equipment and would usually be marked with the same or similar information as would be applicable for main apparatus.
However it should be noted that because of the nature of and relatively small size of the product certain exceptions exist. For example as cable glands are passive in respect of the operation of the electrical system they are not given a Surface Temperature rating (T Rating) during the certification process. In addition because of the amount of marking required and the size limitations of the letters used in applying the marking it is permitted to display information such as the CE mark and year of manufacture on the packaging instead of on the product itself.
CMP Cable Glands would typically be marked in the following manner to demonstrate compliance with the EU ATEX Directive 94/9/EC, and IEC Ex 02 Certification Scheme, which embraces both CENELEC and IEC standards EN 60079 & IEC 60079 :-
Example A : CMP E1FW Cable Gland
Please note that values shown in brackets above are variables that would change according to cable gland or thread size
Some products in the CMP cable gland range may be required to include additional marking for example that required under UL or CSA certification, as shown opposite.
Example B : CMP T3CDS Cable Gland
Please note that values shown in brackets above are variables that would change according to cable gland or thread size.
