Electrical Safety and Low Voltage (LVD) Tests

Laboratorio Test di Sicurezza Elettrica e Prove di Bassa Tensione - INTEK S.p.A.

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.

Experimental Verification of Electrical Safety

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.

Topics Covered

Safety and Dielectric Strength Validation

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).

Low Voltage Regulations and Standards

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:

  • EN IEC 60947 Series: Industrial switching and protection equipment.
  • EN IEC 62368-1: Safety of audio, video, and ICT equipment.
  • EN IEC 61010-1: Safety requirements for electrical equipment for measurement, control, and laboratory use.
  • EN IEC 61439 Series: Low-voltage switchgear and controlgear assemblies.
  • Degrees of protection: IP Code (EN 60529) and IK Code (EN 62262).
  • Special Specifications: Tests in accordance with specifications from manufacturers and national and international network operators.

Below is a complete table of all standards we handle and the corresponding tests that can be performed in the laboratory. The table allows you to quickly filter standards by code or test type.

Vertical Analysis: Insulation, Heating, and Durability

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.

Insulation and Dielectric Strength Testing

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.

Heating and Thermal Monitoring Tests

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 and Thermal Aging Tests

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.

Frequently Asked Questions About Low-Voltage Testing

Why is the heating test considered destructive?

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.
