BS 6121-1:1989 vs IEC 62444 / EN 62444
Whilst new standards such as IEC 62444 and EN 62444 have more recently been introduced, which CMP Products fully complies with, BS 6121-1:1989 still remains a very important benchmark for users and manufacturers around the world, due mainly to the fact that it is a more onerous construction standard than others published. This will therefore be especially relevant where a national cable gland standard isn’t available. The tables below show the maximum cable entry bore size and tolerances permitted through the range of BS 6121-1:1989 cable gland sizes.
Read moreProtection by Enclosure Against Mechanical Impact
It is critically important that enclosures afford a level of mechanical protection relevant to the area of installation that provides optimum electrical and operational safety. The international standard IEC 62262 covering ‘Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK Code)’ outlines the requirements for testing and rating of enclosures of different materials, so that careful selection to suit the application can be achieved.
Read moreCMP Ingress Protection Testing
Some CMP cable gland types have been tested to IP66, whilst other types have been tested to IP66, IP67 & IP68, to an equivalent depth of up to 60 metres for a duration of two weeks. For manufacturers to claim an IP68 protection level it is important that they include both the depth of water and time duration of the test conducted; otherwise the rating would be incomplete and meaningless.
