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..

Testing materials for resistance to ultraviolet light and water according to international standards

We conduct laboratory tests unique for Ukraine on the resistance of materials to atmospheric influences, in particular to ultraviolet (UV) radiation, precipitation, moisture, and condensation, in accordance with international standards (ISO, EN, ASTM), namely EN IEC 60079-0, UL 746C, ISO 4892-2, and others. Testing allows us to determine how a material will behave under the influence of sun and water — whether it will change color, strength, shape, or chemical properties.

The tests are carried out using modern American Suntest XLS+ equipment—a desktop xenon device for rapid testing of materials’ resistance to light and weather. It simulates the effects of sunlight, temperature, and humidity, allowing long-term changes such as fading, yellowing, or loss of strength to be predicted in a short period of time.

What exactly are we testing:

• – Physical and mechanical changes after exposure (loss of strength, cracking, deformation);
• – Change in color, gloss, transparency;
• – Water resistance and hydrophobicity;
• – UV stability (resistance to sunlight/accelerated radiation).

Materials under testing:

• – Explosion-proof equipment;
• – Textiles (clothing, workwear, PPE, tents, tarpaulins, geotextiles);
• – Plastics, films, polymers, PVC;
• – Paint and varnish coatings, paints;
• – Artificial leather, rubber, membranes;
• – Building and decorative materials (facade elements, roofing films);
• – Packaging, labels, composites.

Deadlines for processing:

• Standard tests – 5 to 15 days
• Accelerated aging – by agreement, possibly 250–1000 hours (long cycles)

Determination of material resistance to water penetration by hydrostatic pressure according to DSTU EN 20811

Testing the resistance of a material to water penetration by hydrostatic pressure allows you to determine at what pressure water begins to penetrate through fabric or other materials.
This indicator characterizes the water resistance of the material and is a key criterion for assessing the quality of products designed to protect against moisture — clothing, tents, medical barrier materials, technical and special clothing, and textiles.

Tests are conducted in accordance with the requirements of DSTU EN 20811:2017 (EN ISO 811:2018). During the test, the material sample is secured in a chamber, which is supplied with water with a gradual increase in pressure until the first three drops appear on the surface of the sample. The resulting hydrostatic pressure value (in mm of water column or Pa) is recorded automatically and used to assess the water resistance of the material. Tests can be performed at water pressures from 0 to 3000 cm Н₂О in accordance with DSTU EN 20811:2004, EN ISO 811:2018.

• Use of an ESD generator (simulator) in accordance with the standard (capacitance 150 pF, resistance 330 Ohm)
• Use of reference ground planes and device placement in accordance with the standard diagram
• Measurement of the effect of ESD on equipment operation
• Classification of device response according to compliance levels (classes A, B, C, D)

Who is ESD testing for:

• – Manufacturers of electronics and electrical equipment
• – Importers and distributors
• – Developers of embedded systems
• – Companies undergoing electromagnetic compatibility (EMC) certification
• – Laboratories preparing technical documentation for the EU, Ukraine, or other markets

Why ESD testing is necessary:

1. 1. Protection of products from warranty costs and complaints.
2. 2. Compliance with legislation on Technical Regulations and EMC (mandatory conformity assessment).
3. 3. A necessary stage of product certification in Ukraine and the EU.
4. 4. Ensuring the reliability and safety of electronic devices in real-world conditions.
