Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 
The Type 487 Range of Stopping Plugs is manufactured in brass, steel, stainless steel or aluminium and is designed for the closure of unused entries in flameproof, increased safety or dust protected enclosures. The range covers sizes with metric threads from M16 to M130, other parallel thread forms of equivalent sizes, for example electrical conduit (ET), Pg, BSPP are provided.

Each plug has a threaded portion, 15mm to 20mm long as a minimum, depending on the thread type and size, and a larger circular head with a tapered shoulder. The stopping plug is manufactured with a broached hexagon hole in the larger diameter which is intended for tightening purposes. The underside of the shouldered head may be machined with a groove into which a nitrile or silicone rubber O-ring may be fitted to provide sealing to an associated enclosure.

The stopping plugs, when provided with the O rings and fitted in to suitable equipment, is capable of meeting the requirements of IP66/IP67

 

 
CONDITIONS OF CERTIFICATION: YES as shown below:
 
1. The maximum operation temperature range of the stopping plug when fitted with a nitrile O-ring is -60°C to +80°C.

2. The maximum operating temperature range of the stopping plug when fitted with a silicone O-ring is -60°C to +160°C.

3. The maximum operating temperature range of the stopping plug when fitted with no O ring is -60°C to +200°C.

4. When the stopping plug is fitted in plain holes in increased safety or dust protected enclosures the sealing face of the enclosure is to be smooth and the hole no larger than 0.7mm above the major diameter of the male thread on the stopping plug. The stopping plug is to be secured with a locknut and optional locking washer.

5. When fitted in threaded holes the sealing face of the enclosure is to be smooth, the threaded hole perpendicular to the wall of the enclosure and the thread medium fit.

6. When the stopping plugs are used for increased safety or dust protection and no O ring is fitted the user is to ensure that the enclosure and stopping plug interface is suitably sealed, in accordance with EN 60079-14, to maintain the ingress protection rating of the associated enclosure and protection concept.
