Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 

The Stopping Plugs are used to fill unused threaded cable entries in associated apparatus without compromising the type of protection of the associated equipment They comprise a metallic cylindrical threaded body at one end with a male thread and either a hexagonal head form for securing to associated enclosures, or one of the alternative head forms tabulated below having an additional feature for securing. Some metric threaded designs may also be fitted with a nitrile ‘O’ ring interface seal for better ingress protection. See table below. NPT threaded Stopping Plugs and Types 88- and 89- Stopping Plugs requiring the application of non-setting (solvent free) thread sealant.

 
Material of manufacture:
The part model code "X" is replaced with the following number to indicate the material of manufacture:
TStainless steel grade 316
AAluminium grade   6082-T6(Not certified for Group I use)
RBrass grade CuZn40


 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 

 

1The ranges of Stopping Plugs are not to be used in conjunction with any other cable entry device.
2The stopping plugs are suitable for a temperature at the point of mounting between -50°C to + 85°C.
3The interfaces between the male thread of the products and an associated enclosure female cable entry device cannot be defined. Therefore, it is the user’s responsibility to ensure that the appropriate ingress protection level is maintained at these interfaces.
4The following stopping plugs are to be installed to the following tightening torque values based upon their thread size:
    
 SizeM16M20
 Torque Nm5555
