GRC Battery Testing
What Makes Our GRC Unique?
In our GRC (Group Research Center), we go beyond standard testing. Our approach combines speed, precision, and deep expertise, setting us apart from the competition.
- IN-HOUSE LABORATORY: By managing all testing internally, we significantly reduce lead times and provide faster feedback. This ensures greater control, responsiveness, and efficiency compared to outsourcing to external labs.
- SPECIALIZED BATTERY EXPERTISE: Our forward-thinking vision allowed us to develop battery-specific knowledge years before it became mainstream. Today, we are recognized for our advanced capabilities in this critical field.
- OEM STANDARDS & CUSTOMIZATION: We have extensive know-how of standard tests for every OEM and the versatility to adapt equipment to match customer-specific setups—ensuring full alignment with your protocols and requirements.
- BEYOND STANDARD REPORTING: Our team combines excellent technical knowledge with strong analytical skills, delivering insights that go beyond basic data reporting.
- CUTTING-EDGE TECHNOLOGY: Equipped with innovative, high-precision machines, we guarantee accurate and fast results for every test.
- CERTIFIED QUALITY: Our lab is ISO-certified and undergoes regular quality checks to maintain the highest standards in every process.
- POST-ANALYSIS SUPPORT: We do not stop at testing. We provide consultancy and guidance to help customers refine requirements and optimize future testing strategies.
What We Test and How We Add Value
StokTherm
| ASTM D 5470-17 |
This essential test evaluates the thermal transmission properties of thermally conductive electrical insulation materials, providing a reliable characterization based on a well-known and industry-standard method. Why it matters:
Customer benefits:
|
StokSeal
| PV 3055 | Content of extractable siloxanes |
| Customized approach | Sealing, water tightness, air tightness |
StokShield
| UL94 Horizontal and Vertical | the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing → benefit is to have a fast check of resistance of a material to flame. This helps for screening of possible materials for specific applications |
| Customized approach | Temperature Insulation and heat propagation → hot flow air test to measure deltaT between a surface exposed to a heat source and the cold surfaceà benefit is to have a characterization of materials based on how they can avoid heat propagation and insulate in a limited thickness |
| Customized approach | Fire Protection → by using Bunsen burner and thermocouples GRC can test resistance of materials to direct flame exposure up to 1100 °C |
StokCell
| Customized approach: | compression Set → measuring the permanent deformation of the foam after compressionà this test allows to understand how a material behaves when subjected to compression for long time and at different temperatures |
| Customized approach | Stress-Strain characteristic, compression Force Deflecion bahaviour, Cyclic stress-strein bahavior |
