Committee reference GEL/20/11/1 Draft for comment 03/308266 DC

Foreword

This part of BS 6121 has been prepared by Subcommittee GEL/20/11/1. It supersedes BS 6121‑5:1993 which is withdrawn.

This part of BS 6121 has been updated to refer to the properties of cable glands and armour glands specified in BS EN 50262 and in the new edition of BS 6121‑1, respectively, which specify performance, rather than construction as was the case in earlier editions of BS 6121. Some of the testing recommended in BS 6121‑5:1993 has been removed because this testing is now specified

in BS EN 50262 and/or BS 6121‑1. This revision of BS 6121‑5 includes new recommendations for selection of glands on the basis of mechanical and electrical properties, as well as new clauses relating electrical properties to installation practice.

As a code of practice, this part of BS 6121 takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading.

It has been assumed in the drafting of this standard that the execution of its provisions will be entrusted to appropriately qualified and competent people, for whose use it has been prepared.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope

This part of BS 6121 gives recommendations on the selection, installation and inspection of cable glands conforming to BS EN 50262, armour glands conforming to BS 6121‑1, and accessories, for industrial, commercial and domestic use. It is not applicable to glands for use with fibre-optic cables or mineral insulated cables. It is not applicable to glands for installation in explosive atmospheres.

NOTE Requirements for installation of electrical equipment in explosive gas atmospheres are specified in BS EN 60079‑14. Requirements for installation of electrical equipment in explosive dust atmospheres are specified in BS EN 50281‑1‑2.

This part of BS 6121 is intended for use by specifiers of electrical installations, by installers and by those responsible for carrying out inspections.
