Test Device for Flammability of Plastics for Parts in Devices and Appliances – Basic Version of the UL 94
UL 94 is one of the most widely recognized flammability standards for plastics. It defines methods to classify materials based on how they burn in different orientations and under different conditions. NETZSCH offers dedicated UL94 flammability test instruments designed to perform the full range of UL 94 classifications under controlled and repeatable conditions:
- ASTM Standards: ASTM D635, D3801, D4804, D5048, D4986, ASTM D5025, ASTM D5207
- European Standards: EN 60695 Part 11-10, EN 60695 Part 11-20, EN 60695 Part 11- 3, EN 60695 Part 11-4, IEC EN 60707
- ISO Global Standards: ISO 1210, ISO 9772, ISO 9773, ISO 10093, ISO 10315
The UL 94 Classic is a basic version of the UL 94 device, with simpler manual operation and fewer electronic features. It offers reliable performance at a more affordable price. Both models perform the same flammability tests according to identical standards.
The UL 94 Classic combines proven testing principles with straightforward manual handling — ideal for laboratories that value simplicity, precision, and repeatability.
