# Cable Glands

**Ex ‘n’ gland certification etc.**

According to IEC60079-14, cable glands for **Ex n** (and for **Ex e**) must be certified as meeting the requirements of IEC60079-0.

Glands certified **Ex e** are suitable for **Ex n** use under the new standards.

Before 2007, it was only required that the impact and IP ratings for the type of protection were met, and some uncertified glands could fulfil these criteria.

**Ex nR installation, and cable entries**

**You must consult he particular Ex nR equipment installation instruction**

Gland entries on some **Ex nR** equipment require the use of special sealing arrangements. If so, **restricted breathing seals** or washers will be provided by the equipment manufacturer. The documentation will indicate if restricted breathing seals are required, or if normal IP seals may be used.

To maintain the restricted breathing properties of **Ex nR** equipment via the actual cable glands, **certified Ex d / Ex e / Ex nR glands** are now available, and should be used where applicable.
