Electrical safety testing is the cornerstone of compliance for any electrical or electronic device. The objective of the LVD Directive (2014/35/EU) is not only regulatory but also functional: to ensure that the equipment maintains its structural and insulating integrity throughout its useful life. INTEK analyzes risks related to potential electric shocks, abnormal overheating, and material degradation, providing objective validation of thermal and dielectric safety.
INTEK S.p.A., an independent testing and measurement laboratory founded in 1994 in Rezzato (BS), operates as a strategic partner for global manufacturers and designers. Thanks to a deep metrological expertise and prestigious international accreditations (ACCREDIA No. 00855, UL TPTDP DA928, CBTL IECEE), we provide reliable and traceable measurements for obtaining CE marking and accessing international markets, ensuring that every product meets the highest safety standards.
Validating the safety of an electrical device requires a multidisciplinary analysis that goes far beyond simple document review. By performing tests under load and simulated fault conditions, it is possible to observe how insulating materials and thermal dissipation systems react to real electrical stresses.
This experimental approach allows for the identification of design issues that may not be detected through theoretical analysis alone, such as localized hot spots or insulation losses due to aging or harsh environmental conditions. Observing the testing processes in the laboratory provides technicians and designers with tangible proof of the product’s reliability, reinforcing confidence in its operational safety.
We verify that insulation barriers and components maintain their effectiveness during normal use. Through load simulations and dielectric strength measurements, we analyze the device’s behavior to prevent risks of electric shock or structural failure. The video describes the metrological approach adopted to ensure compliance and safety over time.
In addition to LVD testing, INTEK also offers state-of-the-art technical support for electromagnetic compatibility (EMC) testing).
The INTEK laboratory performs type testing and LVD compliance verification on a wide range of harmonized standards, covering the needs of the civil, industrial, and professional sectors:

The core operations of INTEK’s low-voltage laboratory focus on evaluating product performance from a thermal and insulation perspective—critical parameters for preventing fires and direct contact.
We evaluate the ability of insulating barriers to withstand high voltages and prevent dangerous leakage currents. Tests include insulation resistance measurement and applied voltage testing, which are essential for confirming safe electrical separation between live parts and accessible parts.
Using multi-channel thermocouples and IR thermography, we analyze component overheating during full-load operation and under overload conditions. We verify that the thermal limits of the insulating materials (insulation classes) are never exceeded, preventing premature degradation of the polymers.
Durability tests simulate intensive product use to evaluate its long-term stability. We monitor how insulation properties and mechanical strength evolve under prolonged thermal stress, ensuring the device remains safe throughout its operational life.
In some cases, testing under abnormal fault conditions (e.g., locked rotor or obstructed ventilation) may lead to the controlled failure of the component to verify that there is no risk of fire or loss of insulation.
It is essential to provide the rated voltage, the operating current, the declared insulation class, and the applicable product standard.
Yes, thanks to our UL TPTDP accreditation, we can conduct testing in accordance with UL standards required for market access in the U.S. and Canada.
