Russian Explosion-Proof CertificationRussian Certification

Russian Explosion-Proof Certification, also known as EAC-Ex certification, is an official document verifying that products comply with explosion-proof standards. It is mandatory for explosive hazardous area equipment exported to Russia and Customs Union countries.

The EAC-Ex certification covers complete equipment as well as all accessories and components. Corresponding regional standards include ATEX (Europe), NEC (USA) and CEC (Canada). Only with valid EAC-Ex certification can explosion‑proof products be legally sold and used in Russia.

Common Ex marking definitions:
Ex — Certified by authorized notified bodies;
EEx — Compliant with EU ATEX directives;
d — Type of explosion protection;
IIA/IIC — Explosion hazard classification;
T3 — Surface temperature class.

Manufacturers shall optimize product design and technical documents to meet local explosion‑proof safety requirements. Complete EAC conformity assessment and compile Ex technical files. For assembled products, explosion‑proof certificates of all components and parts (including imported accessories) must be provided.

Russian Explosion-Proof Safety Standards

Current applicable regulations: EAC 22782, EAC 51330, EAC 52350 and EAC IEC 60079. These standards specify classification rules, design criteria, production test methods and marking requirements for electrical equipment in explosive gas atmospheres such as petrochemical industries.

According to EAC 51330.0-99, explosion‑proof electrical equipment is divided into Category I and Category II, including increased safety, intrinsic safety and special protection types. The scope covers telecom equipment, processing, measurement, storage and power conversion devices in hazardous areas with potential ignition risks.

Certificate Features

Mass production EAC-Ex certificates are valid for 1 year or 5 years with annual factory audits. Certificates can be issued to manufacturers, suppliers or purchasers. The overall explosion‑proof grade of the final product shall be determined based on the protection level of each component.
