Testing of explosion-proof equipment
Explosion-proof equipment is used in all industries, manufacturing, and technological processes where explosive atmospheres are present or may be present. Depending on the type of explosive atmosphere present in a given location, different types of explosion protection are used in equipment, and accordingly, different requirements apply to them, and different approaches are used to assess the conformity of such equipment.
In Ukraine, as in the rest of the world, there are mandatory requirements for equipment used in potentially explosive atmospheres. These are the Technical Regulations for Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres No. 1055. This resolution of the Cabinet of Ministers of Ukraine contains requirements for the modules used during conformity assessment, depending on the explosive environment in which the equipment will be used and, accordingly, the type of explosion protection it has.
The cost and complexity of testing and conformity assessment of explosion-proof equipment depend on several key factors:
1. Environment of operation.
Equipment requirements are determined by the composition of the explosive atmosphere (gas or dust mixture, auto-ignition temperature, etc.) and the area of application — from mining equipment to machinery for gas or dust environments.
2. Zone classification.
The higher the risk level (an area where an explosive atmosphere is present continuously or periodically), the stricter the requirements and the more extensive the conformity assessment procedure.
3. Equipment type.
Simple equipment (such as lamps or junction boxes) requires less expertise. At the same time, complete installations — combines, pump units, lifting machines, fuel dispensers — require comprehensive technical expertise, which makes the process longer, more complex, and more expensive.
Based on the results of certification tests and trials, a test report is drawn up, which is one of the grounds for the conformity assessment body to decide whether to issue a certificate of conformity.

Cost of testing
The cost and complexity of such tests and conformity assessments depend on the zone and composition of the explosive atmosphere, as well as the type of equipment and type of explosion protection.
The more complex the type of explosion protection, or the combination of several types of explosion protection, the more extensive the requirements and the verification of these requirements for products, the scope of testing and technical expertise. This determines the cost of testing and conformity assessment of equipment and protective systems intended for use in potentially explosive atmospheres.
For an initial analysis of the scope of work and determination of the conformity assessment procedure, it is MANDATORY to know the explosion protection marking of the equipment, as well as to have a general description of the products, nominal characteristics, photographs, drawings, and electrical diagrams. Our specialists will review your request and technical documentation and quickly and efficiently answer your questions, as well as help you choose the conformity assessment procedure for your equipment free of charge..

Industry
We have prepared answers to frequently asked questions from customers.
1. Electrical equipment: distribution cabinets, lighting fixtures, motors, sensors, switches, automation devices.
2. Mechanical equipment: gearboxes, pumps, fans, mixers, compressors, even if they do not have electronic components.
3. Protective systems: devices or components designed to stop an explosion or limit its impact (e.g., explosion relief valves).
4. Components that do not operate independently but are designed to be integrated into explosion-proof equipment.
5. Control and diagnostic systems that ensure safe operation in areas with explosion risk.
Equipment is classified into groups (I, II, III) and categories (M1/M2, 1/2/3) depending on the level of explosion protection and the area of application. If your equipment is intended for use in oil refineries, chemical, pharmaceutical, agricultural enterprises, elevators, or mines, it is most likely subject to the requirements of this regulation.
