To better assess the hazard potential of tests, EUCAR (European Council for Automotive R&D), a consortium of European car manufacturers, has investigated hazardous situations and divided them into eight risk classes. The development of the safety equipment of our battery test systems is also based on this classification:
A. High/Low Temperature Cycling Chambers Humidity Chambers
B. AGREE Temperature/Vibration Chambers Altitude Chambers
C. Explosion Proof Chambers
D. Performance and ageing tests
E. Climate tests
F. Environmental simulation tests
G. LV-124 tests
Our Battery Explosion-Proof Testing Chamber could fulfill all of the following test specifications:
IEC 62660-2
SAE J2464
IEC 60086-4
UL 1642
UN Lithium Battery Testing
IEC 61960
IEC 62133
UL 2054
IEEE 1625
IEEE 1725
STS provides safety features for reliability and abuse testing of batteries. Each environmental simulation chamber is designed with safety in mind. Our Engineering team will review your test requirements and incorporate applicable test chamber safety features for the specific battery test application. Below is a list of safety features that may be incorporated into STS test chambers and tailored to the various hazard levels (0 – 7) to help mitigate potential risks
| Hazard Level | Description | Safety level and results |
| 0 | No effect | No effect no functional limitation. |
| 1 | Start of passive safety system | No damage no leakage, no gas leak, no fire, no fracture no explosion, no exothermal reaction, no thermal runaway. Cell reversibly damaged, repairs of safety installations necessary. |
| 2 | Damage | No leakage, no gas leak, no fire, no fracture, no explosion no exothermal reaction, no thermal runaway. Cell reversibly damaged, repairs of safety installations necessary. |
| 3 | Leakage (weight loss < 50%) | No gas leak, no fire, no fracture no explosion. Leakage of electrolyte < 50%. |
| 4 | Gas leakage (weight loss > 50%) | No fire, no fracture, no explosion. Leakage of electrolyte > 50%. |
| 5 | Fire | No fracture no explosion no flying parts. |
| 6 | Fracture | No explosion, but flying parts of the active mass. |
| 7 | Explosion | Decomposition of the battery cell. |
