Electrical Product Safety
Low Voltage Directive & Compliance
You will need to prove that your electrical and electronic products meet the safety standards and requirements of their destination marketplace if you want to sell it on the global market. The certification according to the European Union’s Low Voltage Directive (LVD) 2014/35/EU ensures the flawless operation and protection against electric hazards or shocks. We offer you comprehensive product testing for electrical safety.
IB-Lenhardt AG and IBL-Lab GmbH perform electrical tests and assessments in the DAkkS-accredited laboratories using the latest testing equipment. We evaluate your electrical product for conformity and affix the CE mark for market access.

Various Influences on Product Safety
The hazards that can emanate from electrical products are differentiated according to the type and "size" of the associated energy source, which are then investigated according to the catalogue of requirements:
The compliance with correct insulation coordination is one of the most important issues, such as protection against body currents in order to prevent fatal consequences. Devices such as plug-in power supplies, chargers, laptops, IT equipment and household appliances are thoroughly tested for their isolation capability.
Electrical systems generally represent a fire hazard in the household. Harmonized standards offer approaches to reduce the probability of occurrence or to deal safely with potential fires inside of the enclosures. In the absence of proofs of the common fire classes HB or V-0 (ANSI / UL-94), substitute tests can be carried out in the laboratory to avoid time delays.
Devices should be equipped with stable enclosures. If the enclosure has no obvious additional functions, such as electrical insulation, for example in the case of Class II units, or when it serves as a fire protection enclosure, the requirements for mechanical stability increase.
Temperatures during normal operation as well as single-fault testing are examined. On the one hand, burn injuries must be avoided while users touch a device. On the other hand, the operating temperatures of critical components must be observed.
Under this term you can find sources such as X-rays, bright light, sound pressure, laser and electromagnetic fields.
Needle-Flame Test Method
With regard to flammability requirements, the needle-flame test is widely accepted to support ad-hoc verification of for example V-0 or V-1 of plastic materials. The fully automated system reduces manual errors and results in a more comparable outcome.
The test flame, applied to the test specimen, imitates a flame that might arise from a component that is close to the test specimen in the real application. Such a flame might have occurred, for example, because of an electrical fault. We perform the testing according to IEC 60695-11-5 to meet the respective requirements of your electrical product.
Glow-Wire Flammability Test
Glow wire testing is a indirect flame method for plastics according to IEC 60695-2-11 to prove the suitability as an insulating part of an electrical or electronic device. The testing is performed by heating an element to a pre-determined temperature. The sample to be tested is fixed and a tissue paper is placed directly under the sample. After reaching the specified temperature, the element is pressed into the sample material for 30 seconds with a specified force of 1N. If ignition occurs, the duration and height of the flame are recorded and it is noted whether drops of the material ignite the tissue paper.

Frequently Asked Questions
All you need to know about safety testing
- Why is electrical safety testing so important?
Every year many electrical shocks occur with the consequences of injuries or even deaths related to the use of electric products. To avoid the risk of electrical shocks to customers, it is necessary to ensure safety compliance with national and international standards to evaluate the potential risks of electrical shocks when using a product.
- What are the advantages for the end product if its components are already tested according to the safety standard?
One of the biggest advantages is the cost factor. For example, power supplies, transformers, VDRs or similar can be installed in the device. In this case, they are only tested for their area of application according to 62368-1. Safety-relevant components must be certified according to certain standards. Otherwise, these components would have to be tested separately.
- What are protection classes?
Protection classes are the classification of electrical equipment according to their level of protection. They define safety measures that protect against voltages that are dangerous to touch. In the EU, there are three protection classes (class I, II, III), which are represented by symbols.
- What is the purpose of the needle-flame test?
The needle-flame test is a method that involves burning a small sample of the material with an open flame, usually from a butane lighter or torch. The material is then observed for any signs of combustion, such as smoking or flaming. This test can be used to measure how quickly and easily something will burn when exposed to an open flame. It can also help identify which types of materials are more likely to cause fires if left unattended in hazardous areas.
- What does an electrical safety analyzer measure?
An electrical safety analyzer is an instrument used to perform the different safety tests to evaluate that the tested device is in compliance with electrical safety requirements. Often it is used to test medical equipment.
