Your specialists for testing plastic components for the automotive industry

We are partners of the automotive manufacturers and their suppliers

Beyond the requirements of DIN EN ISO/IEC 17025 or VDA 250, many automotive manufacturers have developed their own criteria for test laboratories regarding automotive release testing. Based on accreditation according to DIN EN ISO/IEC 17025, testing laboratories are approved or recommended by OEMs for certain procedures.

We look at all material requirements from the ground up and support you in meeting the standards of the automotive manufacturers. Our many years of experience in testing plastic parts and our comprehensive range of tests in the field of automotive testing will help you find the best solutions and meet the highest requirements.

Contact us, we will be happy to help you!

Initial sample testing according to manufacturer standards

In order to prove the quality of products in the automotive sector, each OEM has issued numerous specifications which must be confirmed by an accredited laboratory, and in some cases also by a laboratory specially approved by the OEM, as part of the initial sample tests. The specifications are usually defined in one or more delivery specifications. However, a delivery specification usually applies to very different components (e.g. VW's TL226 generally applies to painted components in the vehicle interior). In addition, there may be differences in the scope of testing depending on the installation location, material or surface finish. A delivery specification generally only defines which test is to be carried out and in some cases also gives specifications. The actual tests are in turn described individually in separate test specifications or standards. These can be test specifications of the OEM or general DIN or ISO standards, but also standards of the German Association of the Automotive Industry (VDA).
 

Analytik Service Obernburg (ASO)

An overview of the manufacturer's standards, which is required within the scope of the initial sample inspection, can be found at Analytik Service Obernburg (ASO). ASO is a company of the SKZ Group with focus on raw material analysis, product analysis as well as failure analysis.

GS 93016

BMW approval according to GS 93016

Test laboratory approved by the BMW Group

Due to the continuous update of the group standard 93016 for plastics and thermoplastics at the BMW Group, the inclusion of material trade names and material certification is newly regulated. In addition to a wide range of practical and theoretical requirements, a release test by a BMW-approved laboratory is mandatory for raw material manufacturers and for materials. The type and number of tests have been defined by the BMW Materials Development Department.

To date, five laboratories worldwide have been approved by the BMW Group to perform these tests. Among them are the testing and laboratory facilities of the SKZ in Würzburg. Here, quality testing and quality assurance have been successfully carried out for decades. The acceptance as an official testing laboratory by the BMW Group is both an award and an incentive for the engineers and scientists at SKZ.

10 steps to successful testing according to GS 93016

1. Inquiry of the materials to be tested

In order to carry out the listing process we need information about the type and number of materials to be approved for the BMW Group.

We ask for the following information

  • The number of semi-crystalline materials: Do the objects contain PA? 
  • The number of amorphous materials: Do the objects contain ABS?
     
2. Transmission of the test program

To enable us to start the process implementation quickly, please send us the test program required by the BMW Group for your listing.

3. Processing guidelines and documents

Use the possibility to send the processing guidelines of the materials conveniently by e-mail. Of course, you can also send us all other documents by e-mail.

4. Individual offer

We look forward to receiving your documents and will be happy to prepare your individual offer after reviewing them.

5. Order

We look forward to receiving your order and at the same time assure you of prompt and professional processing.

6. Test object

Subsequently, you provide us with the granulate(s) for testing.

7. Test specimen

The production of the test specimens is part of the test program and is carried out by us.

8. Analytical and mechanical tests

Now the actual analytical and mechanical tests for listing in GS 93016 begin.

9. Test report

The SKZ prepares a test report with the required material characteristics.

10. Test protocol

In addition, we will send you the results report and the laboratory protocols in order to submit the application for release of the tested material to BMW.

LV 312-3

Corrugated hose tests according to delivery specification LV 312-3

Test laboratory accredited by DAkkS

The LV 312-3 delivery specification is specifically intended for use with cable protection systems in the automotive sector. As a result, it serves to ensure quality in a highly sensitive area of application.

Cable protection systems are exposed to demanding conditions during their service life: Engine heat, cold in winter, moisture and also the influx of chemicals are all possible. Corrugated hoses must be able to withstand these demands for many years in order to ensure the protective function and electrical safety of the cable harnesses in the vehicle. Therefore, these plastic elements must meet stringent requirements, which are specified within the scope of delivery specification LV 312-3. The underlying test program essentially comprises mechanical tests, aging and resistance tests, and tests for compatibility with adhesive tapes or cables. This ensures that the tested corrugated hose is suitable for use in the vehicle.

LV 312-3 covers a total of 37 tests for corrugated hoses, including inner and outer diameter, notch strength, chemical, abrasion, UV and flame resistance, and long-term aging. The products that can be tested according to delivery specification LV 312-3 at the SKZ are corrugated hoses in the versions slit and non-slit, open and overlapping.
