W-line Laboratory specializes in the preparation of technical documentation, as well as conducting various types of testing in the fields of non-ionizing radiation, electrical installations, and workplace environmental parameters. Our goal is to provide clients with comprehensive support — from expert measurements to complete documentation required for obtaining permits and operational approvals.
If you require testing, expert opinion, or project documentation, contact us — our team will help you find the optimal solution in compliance with applicable regulations and standards.
In addition to testing and measurements, W-line Laboratory also prepares technical documentation required for obtaining operating permits for sources of non-ionizing radiation in the environment. This includes the following:
Test reports provide a detailed presentation of the results of conducted measurements, depending on the type of testing performed. The reports present measured values, their comparison with relevant regulations, and prescribed limit values for the respective field. Where required by applicable regulations or standard requirements, the report also includes a Declaration of Conformity, confirming that the measured values meet all criteria defined by the relevant standard or regulation.
Expert assessments include an analysis of the impact of high-frequency non- ionizing radiation sources on the environment, such as mobile network base stations, FM radio stations, TETRA base stations, and similar sources. These assessments form the basis for obtaining operating approvals and contain all necessary data on radiation levels, environmental exposure, and compliance with prescribed limit values. An integral part of the expert assessment is the report on measurements of electromagnetic field levels in the surroundings of the tested location.
Environmental impact assessment studies include a detailed analysis of high-frequency non-ionizing radiation sources, such as mobile network base stations, FM radio stations, TETRA base stations, and other emission systems. The aim of these studies is to comprehensively assess the impact of planned or existing radiation sources on the environment and to define protection measures in accordance with applicable regulations and standards. Based on the completed study, a decision is issued by the Ministry of Environmental Protection confirming that the radiation source meets all prescribed safety and environmental protection requirements.
These tests are conducted to determine
exposure levels to electromagnetic fields
originating from high-frequency sources
such as base stations, FM radio, TV
transmitters, and wireless
communication networks. Measurements are primarily performed in
areas where people live or work —
residential and commercial buildings,
schools, healthcare facilities, and their
The frequency of measurements
depends on the type of facility and
applicable legal regulations. They are most commonly carried out
before putting into operation, Ispitivanje

visokih frekvencija, or periodically as part
of routine monitoring of existing non-
ionizing radiation sources.
Used to determine the overall level of electromagnetic field in a given area, without frequency decomposition. This method enables fast and efficient assessment of exposure in real environments, which is particularly important for indicative and control measurements.
Used for detailed analysis of
electromagnetic radiation sources and
identification of individual frequencies
under real operating conditions.
Enable precise determination of each
individual source’s contribution to the
total electromagnetic field level.
These tests include measurements of
electromagnetic fields generated by power
facilities, cables, substations, and other
sources of low-frequency voltages and
currents. Measurements are typically carried out in
working and residential spaces, as well as
their surroundings, in order to assess
human exposure to electromagnetic fields. The frequency of measurements depends
on the type of facility and changes in
operating conditions. They are most commonly performed during
the putting into operation new power
systems or as part of regular inspections of
these systems, in accordance with
applicable regulations and standards.

Used to determine the overall level of
electromagnetic radiation in a given area,
without frequency decomposition.
This method enables rapid assessment of
overall exposure to low-frequency
electromagnetic fields, especially in
environments where power-related sources
are present.
Used when it is necessary to analyze
individual electromagnetic field components
and identify radiation sources within the
low-frequency range.
This method enables a more detailed
assessment of exposure levels and
comparison with reference values
prescribed by applicable standards.
This includes inspection and testing of
electrical installations in low-voltage
facilities, in order to ensure compliance with
technical regulations and electrical shock
protection standards. Measurements are most commonly
performed in residential, commercial, and
industrial facilities during the commissioning
of new installations, periodic inspections, or
after reconstruction of the electrical power
system. The purpose of these tests is to ensure the
safe operation of electrical equipment and
the protection of people from potential
hazards.

These tests are conducted to verify the correctness and effectiveness of lightning protection systems. The tests include inspection of continuity, earthing resistance, and functionality of all lightning protection system components, in order to ensure reliable protection of buildings and people. Measurements are typically carried out during the construction of new facilities, after reconstruction, or periodically, in accordance with applicable regulations and standards for protection against overvoltage and atmospheric discharges.

W-line Laboratory is in the process of expanding the scope of its accreditation, which will include methods for power quality testing in accordance with SRPS EN 50160:2023 and SRPS EN 61000-4- 30:2015 standards. These tests enable the analysis of voltage parameters, frequency, and harmonics, allowing assessment of the stability and reliability of the power supply system. The objective is to ensure power supply quality in line with user requirements and technical regulations, contributing to safer and more efficient operation of electrical equipment.

These tests are conducted to verify the conductivity and resistance of floor coverings designed to prevent the accumulation of static electricity. They are carried out in areas where static electricity may pose a risk — such as industrial facilities, laboratories, server rooms, and production areas with sensitive electronic equipment. Measurements are performed in accordance with applicable standards in order to confirm the effectiveness of protection and the safety of the working environment.

These tests are conducted to determine whether lighting levels in working areas comply with applicable standards and occupational safety regulations. Measurements assess whether the level and distribution of light provide safe and optimal working conditions, without visual strain or reduced productivity. These tests are performed in offices, production halls, warehouses, and other working environments. They are carried out during the commissioning of new facilities, changes to lighting systems, or periodic inspections of working conditions.
