Explosion Safety Certificate
Certification of explosion proof equipment is one of the key activities of EMC CENTRE. The certification is conducted against compliance to Technical Regulation "On safety of equipment intended for use in explosive atmospheres" (TR CU - 012 - 2011).
Ex-Certificate is issued to testify the product conformity to the requirements of explosion safety (other titles:TR CU Certificate, Explosion Proof Equipment Certificate and Explosion Safety Certificate).
This Technical Regulation applies to electrical equipment including ex-components and non-electrical equipment for explosion hazardous environment operations.
Ex-component is a device fitted to explosion proof equipment to provide safe operations in explosion hazardous environment. The device is not intended for stand-alone operation.
Explosion hazardous environment means the following conditions are present concurrently:
- Flammable substance (dust, gas, suspensions, vapor) (A)
- Oxygen: always present in surrounding atmosphere (B)
- After ignition (C) fire spreads out to all underfired mixture (in case of fiber the dust could combust partially).
Ex-proof equipment and Ex-components are characterized by having an explosion safety appliances declared by manufacturer and also labeling.
Following standards are used for Ex-equipment certification:
- State standards for Ex-equipment harmonized with IEC and EN;
- Rostechnadzor standards.
The considered Technical Regulation is not applicable for:
- Medical products;
- Equipment that could turn unsafe if explosion hazardous substances and/or unstable chemical mixtures are present;
- Domestic appliances if explosion hazardous environment develops due to escape of gaseous fuel;
- Personal protective equipment;
- Sea vessels, inland water ships, mobile offshore structures and drilling platforms for sea and inland water operations, as well as their machinery and equipment;
- Public transport designed to carry passengers and cargoes by land, sea and air as well as other watercrafts;
- Nuclear weapons and research equipment for nuclear defense complex excluding equipment operating in explosion hazardous areas.
Equipment intended for use in explosion hazardous environment is ranked (EU standards, areas, temperature codes and existing types of protection) according to ATEX 94/9/EC Directive. The Directive was adopted in EU to facilitate international trade by harmonizing legal and technical requirements for an equipment to use in potentially explosion hazardous environment in member countries.
The Directive applies to systems and equipment that might be operated in potentially explosion hazardous environment due to presence of combustible gases, vapors and dust. It is also applicable to electrical and mechanical equipment. The Directive harmonizes requirements and defines evaluation procedures for compliance to such requirements.
User is solely responsible for the operation of equipment according to discretionary ranking of hazardous areas. That means operations depend on users' risks evaluation. Equipment installation and operation must comply with 94/9/EC Directive.
EMC CENTRE cooperates with Russian leading designated company - Certification Authority for Explosion proof Equipment that employs high skilled staff, including Rostechnadzor and International Certification System experts.
