Quality tests

Quality in every application

The quality of our products is our top priority. Quality is not only tested retrospectively on finished products, but is ensured responsibly at every stage of our production and logistics operations.

To ensure the use of our products in all relevant industries, our products undergo a wide range of test procedures. Along with standard test procedures in accordance with IEC 60947-7-1/-2/-3, our products are also subject to specific quality tests where they are qualified in accordance with numerous approvals.

Basic principles of quality testing

The quality of our products is our top priority. Quality is not only tested retrospectively on finished products, but is ensured responsibly at every stage of our production and logistics operations.

To ensure the use of our products in all relevant industries, our products undergo a wide range of test procedures. Along with standard test procedures in accordance with IEC 60947-7-1/-2/-3, our products are also subject to specific quality tests where they are qualified in accordance with numerous approvals.

Mechanical tests

Tests on the mechanical properties of a terminal block

Tests relating to the mechanical properties of a product
The mechanical quality tests are primarily used to test the clamping part and insulating housing. These tests focus on the product’s ability to withstand various influences such as vibration, conductor movement, and conductor pull-out or its mechanical strength. By performing these quality tests, we are able to guarantee you the highest quality standards with respect to the mechanical properties.

Examples of mechanical tests:

  • Connection capacity
  • Flexion test
  • Conductor pull-out test
  • Mechanical strength
  • Temperature shock test

Electrical tests

Electrical tests
Quality tests relating to the current flow of products
The electrical quality tests concern the current flow in the products. They involve imitating various scenarios in which the terminal blocks are tested for short circuits or heat generation, for example.
The creepage distances and insulation properties of the terminal blocks are also tested to ensure adequate electrical isolation. To ensure the efficiency of the individual products, they are also tested with respect to voltage drop. Examples of electrical tests:

  • Temperature-rise test
  • Dielectric test
  • Air clearances and creepage distances
  • Voltage-drop test
  • Surge voltage test

Material tests

Test relating to the material properties of products

Test relating to the material properties of products
Material tests are used to check the products for material changes. The focus of the material tests is on longer load tests in the form of constantly higher temperatures, the development of creepage due to moisture and dirt, and the simulated aging of materials.
Examples of material tests:

  • Aging test
  • Inflammability classification
  • Insulating material properties
  • Corrosion test
  • Needle flame test
