Equipment and systems covered by this certificate are as follows

The Scancon Blind Plugs are blanking elements available in thread sizes M20 x 1.5, and M25 x 1.5, and manufactured from stainless steel.  They are to be fully tightened into threaded holes on thick-walled flameproof and dust protected enclosures to form a threaded joint such that minimum thread engagement requirements are met.

The operating temperature range is -60°C to +120°C.

  • The operating temperature range is -60°C to +120°C.   The temperature locally and internally to the blind plugs when fitted into an enclosure must be taken into account, in addition to the external ambient temperature range.
  • When fitted to a non-metallic/non-conductive enclosure conformity with clause 7.5 of IEC 60079-0:2011 (Accessible metal parts) must be confirmed.
  • When used in flameproof (Ex d) applications, the wall of the flameproof enclosure into which it is fitted shall be such as to maintain at least 5.34 full threads or 8mm of engagement.
  • Blanking elements must not be used with a thread adaptor.
