Additional Information

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.

Generic Cable Considerations

Unarmoured Cables When cable glands are designed to suit a range of different cable types they will often provide basic sealing and mechanical retention through the use of a sealing ring on the cable outer sheath, for example, in the case of an unarmoured or screened cable. Cable gland solutions for unarmoured cable would need to cater for a reasonable acceptance range so that the most popular cables fit comfortably within the minimum to maximum range.

Industry Standard Cable Gland Designations

Cable glands may be designed, tested and manufactured to various standards around the world, but as a long established UK-based manufacturer, part of CMP’s history includes close participation in the development of British Standards for these products.
