Accredited testing of plastics and rubber

Get impartial and accredited documentation of your plastic materials' properties - for quality assurance, product development, and CE marking.
Accredited testing of plastic materials is an independent third-party verification of whether a material or product complies with specified requirements in recognized standards published by ISO, ASTM, UL, or CEN. The testing provides you with documentation that you can use with customers, regulatory authorities, and business partners - across markets and national borders.
Danish Technological Institute is an accredited testing laboratory with one of Denmark’s broadest commercial programs within the testing and analysis of polymer-based products and materials. We assist with everything from standardized mechanical testing to customized functional tests.
How can Danish Technological Institute assist you?
The specialists at Danish Technological Institute can assist with:
- Service life: assess the durability of your product before or after commercialization
- Accredited comparative testing: document your product’s properties compared to equivalent products on the market
- Mechanical testing: map changes in mechanical properties such as strength, stiffness, and impact resistance
- Quality control of raw materials and intermediate products: verify the quality of incoming materials
- Testing prior to CE marking: obtain documentation supporting correct CE marking
- Accredited test reports: receive impartial documentation recognized nationally and internationally
- Customized functional tests: we design a test setup tailored to your specific product and requirements
- Mathematical extrapolation: advanced modeling of measurement data, e.g., for estimating long-term properties
Why is accredited testing important?
When documenting the quality of a rubber or plastic product, accredited testing is the strongest documentation you can obtain. An accredited test report from Danish Technological Institute is an independent confirmation that your material meets the requirements set out in relevant standards.
This is essential in a range of situations:
- When you need to CE mark a product
- When customers or authorities demand impartial documentation
- When comparing materials from different suppliers
- When documenting product quality for international markets
Common standards such as ISO, ASTM, and DIN make it possible to compare material properties across companies, suppliers, and national borders – and an accredited report ensures that the comparison is valid.
Broad capability in plastics testing
Danish Technological Institute possesses one of Denmark's largest competence centers within rubber and plastic components. The laboratory covers a broad commercial program of standardized tests and analyses, performed by experienced specialists.
The tests include, among other things:
- Mechanical properties - e.g., tensile strength (ISO 527), flexural strength (ISO 178), impact strength (ASTM D256), and hardness (ISO 868)
- Cosmetic and visual assessment - documentation of changes in surface appearance
- Aging and service life - accelerated tests simulating long-term environmental exposure (ISO 11346)
- Material control - verification of raw materials and semi-finished products against specifications
When standards fall short - customized tests
Not all products can be tested according to an existing standard. If your plastic product features unique geometry, application, or load profile, the specialists at Danish Technological Institute can design a customized functional test based on the product’s actual conditions of use.
We can also offer advanced mathematical extrapolation of measurement results - e.g., for estimating long-term properties where it is not practically feasible to await a full-scale service life test. An Arrhenius-like temperature dependence is often well-suited for chemical reactions (e.g., oxidative degradation). However, if the aging involves a physical change of a viscoelastic material, the Williams-Landel-Ferry (WLF) model is more appropriate.
