Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 
The EXIOS BARRIER Range of Barrier Cable Glands are metallic and are intended for use with armoured or unarmoured cables. They allow the entry of the cable into enclosures without compromising the explosion protection provided by the enclosure, in accordance with relevant codes of practice.
The EXIOS BARRIER Range of Barrier Cable Glands, when installed with a sealing ring and in accordance with the manufacturer’s instructions, are capable of providing, with an enclosure on which they are fixed, an ingress protection rating of IP 66 and IP68 to 50 metres for 30 minutes.
The EXIOS BARRIER Group I range comprises the following sizes:
*Metric sizes M20 (22 A/F), M20 (24 A/F), M20 (30 A/F), M25, M32, M40, M50, M63, M75
*NPT sizes 1/2"(22 A/F), 1/2" (24 A/F), 1/2" (30 A/F), 3/4", 1”, 1 ¼”, 1 ½”, 2”, 2 ½”, 3”
The EXIOS BARRIER Group II range comprises the following sizes:
*Metric sizes M16, M20 (22 A/F), M20 (24 A/F), M20 (30 A/F), M25, M32, M40, M50, M63, M75
*NPT sizes 3/8”, 1/2"(22 A/F), 1/2" (24 A/F), 1/2" (30 A/F), 3/4", 1”, 1 ¼”, 1 ½”, 2”, 2 ½”, 3”
The EXIOS BARRIER range may be manufactured from the following materials:
*Brass grade CW614 (CuZn39Pb3)/ CZ121 3Pb
*Stainless Steel grade AISI 316L (1.4404)
Additionally, brass may be provided with Nickel plating.


 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 

1

The cable glands shall not be used in enclosures where the temperature, at the point of mounting, is outside the range of -60°C to +85°C.
2The entry component threads will be suitably sealed using a method that is applicable to the associated equipment to which the gland will be attached.   This will be in accordance with the relevant installation code of practice and will ensure that any ingress protection requirements are maintained.
3When glands without sealing rings are installed in an explosive dust atmosphere, they shall only be fitted into enclosures that provide cable entries with a minimum of 5 fully engaged threads, this is in accordance with clause 5.1.1 of IEC 60079-31:2008.

 EQUIPMENT(continued):
 
 
The glands comprise from front (enclosure side) to rear (incoming cable side):
*Entry body to tighten into an associated enclosure which is fitted with a sealing ring; the front and rear having male threads.
*Front ferrule that fits into the entry body. The ferrule body is the main part of a two part chamber where a two-part epoxy putty setting compound is applied to provide an inner seal around the conductors. The external face when fitted into the entry body makes an unthreaded cylindrical flamepath.
*O-ring located between the entry body and mid cap to provide an ingress seal to the unthreaded flamepath between the entry body and front ferrule.
*Rear ferrule/ cone, second part of a two part compound chamber at front and cone for clamping cable armour, when available, at rear.
*Clamp ring that secures cable armour, when available, to the cone and also provides earth protection. The clamp ring must be used, even when unarmoured cables are used.
*Middle cap that has female thread at the front and secures ferrules in place within the entry body; the rear of the middle cap has a male thread to accept the back nut.
*Elastomeric cable outer sheath seal, fitted within the back nut.
*Non-metallic compression ring, fitted between outer sheath seal and back nut.
*Back nut with female thread that screws into the middle cap to compress the outer sheath seal.
