GOST R -ex certificate.

The certificate of conformity of Ex-equipment (explosion protection certificate, the certificate Ex,  Ex certificate of conformity GOST R, GOST-ex certificate) - a document certifying that Ex-equipment meets the standards for explosion protection.

Ex-equipment is divided into two groups:

• Group I Mine Explosion products - a dedicated electrical equipment intended for the mines, quarries, mining and processing enterprises.

• Group II Explosion-proof electrical equipment for indoor and outdoor use, designed for potentially explosive atmospheres, except for the underground workings and mines.

Marking of Ex-equipment is made ​​by the manufacturer. Simultaneously with the mark of conformity the manufacturer shall affix explosion-proof marking , specified in the certificate.

Documents required to apply for the GOST-EX certificate:

  • technical description;
  • manual;
  • schematic diagrams, drawings, design documentation;
  • ATEX certificate
