Product Safety Testing

On December 20, 2020 the old harmonised standards IEC 60950-1 and IEC 60065 lost their presumption of conformity and were subsequently replaced by IEC 62368-1 and EN 62368-1.

Until this day, all relevant products should be reevaluated according to IEC 62368-1 in order to stay compliant to the Radio Equipment Directive (RED) or to the Low Voltage Directive (LVD) of the EU.

Thanks to the transition from technology-based requirements to a new, hazard-based approach, it is now possible to assess a wide variety of products in the same way.

In addition, the hazards are now differentiated according to the power and type of the associated energy source:

  • Electrical

  • Power

  • Mechanical

  • Thermal

  • Radiation

Safety Testing Standards

Benefit from the services of the modern equipment of our laboratory, which is accredited by DAkkS with the accreditation certificate D-PL-21375-01-01 according to DIN EN ISO/IEC 17025:2018:

  • DIN EN IEC 62311
    Assessment of electronic and electrical equipment related to human exposure restrictions for electromagnetic fields (0 Hz to 300 GHz)

  • DIN EN IEC 62479
    Assessment of the compliance of low-power electronic and electrical equipment with the basic restrictions related to human exposure to electromagnetic fields (10 MHz to 300 GHz)

  • DIN EN IEC 62368-1 ed.2 & ed.3
    Audio/video, information and communication technology equipment Part 1: Safety requirements

  • DIN EN IEC 61010-1
    Safety requirements for electrical equipment for measurement, control, and laboratory use Part 1: General requirements

  • IEC 60695-2-11
    Fire hazard testing—Part 2-11: Glowing/hot-wire based test methods—Glow-wire flammability test method for end-products (GWEPT)

  • IEC 60695-11-5
    Fire hazard testing—Part 11-5: Test flames—Needle-flame test method—Apparatus, confirmatory test arrangement and guidance

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 if the need arises. The fully automated system reduces manual errors and results in a more comparable outcome. 

Various Influences on Product Safety

Various energy sources can be identified as the cause of injury or fire, which are then investigated according to the catalogue of requirements:

  • Electrical
    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. Numerous requirements depending on the overvoltage category for the insulation materials, housing materials, labeling, manuals and the selection of the correct components are intended to protect users from harm such as contact voltage.

  • Power
    Furthermore, electrical appliances generally represent a fire hazard in the household that should not be underestimated. Harmonised standards offer approaches to reduce the probability of occurrence or to deal safely with potential fires inside of the enclosures. The synergy of plastic materials with appropriate flammability classes, possible sources of ignition and perhaps openings in the housing, result in a lower risk of fire. 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.

  • Mechanical
    It is expected that devices are 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. Larger devices pose high risks such as tipping over, falling off when mounted to a wall or insufficiently designed handles.

  • Thermal
    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.

  • Radiation
    This item includes sources such as X-rays, bright light, sound pressure, laser and electromagnetic fields.

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.
The procedure of electrical safety testing evaluates the potential risks of electrical shocks when using a product and helps to improve the devices for fulfilling all the requirements of electrical safety standards.

What is part of an electrical safety test?

The following tests are described in different national and international standards:

  • High Voltage Test (Dielectric Voltage-Withstand Test): During this test the device is applied by a higher voltage than usual. The ability of the product to withstand a high voltage is important to pass the test.

  • Leakage Current Test (Line Leakage Test): This test measures the leakage current between an AC source and the ground through the protective surface of the insulation. This current is not desired and can be harmful for human bodies. It should not exceed the acceptable limit.

  • Insulation Resistance Test: This test measures the quality of the protective conductor of the product.

  • Ground Continuity Test: Ensures that a clear path is available between all exposed metal surfaces and the power system ground.

  • Temperature Test: In specific climatic chambers the product is tested for its response to extreme temperatures.

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.
