NOTES:
- SPMH type stopping plugs are designed for use within either clearance holes or parallel threaded entries, for taper threaded entries
we would recommend the use of SPA type stopping plugs
- Full installation instructions are supplied with stopping plugs, the instructions must be read prior to installation and adhered to in
full
- Unless otherwise stated ISO Metric entry threads have a 1.5mm pitch
- For Flameproof Exd applications the female thread into which the stopping plug is to be fitted must comply with clause 5.3 of EN
50018:2000 (clause 5.3 IEC 79-1)
- For NEC/CEC Explosion Proof applications an engagement of at least 8 full threads must be achieved for parallel threads and 5 full
threads must be achieved for tapered threads
- Where metallic stopping plugs are fitted into non-metallic Increased Safety Exe enclosures they must be included within the earth
circuit of the system
- When ordering one needs to specify if IECEx or ATEX certification is required. ATEX versions are supplied as standard.
