Test Equipment & Setup

Item Detail
Instrument Thermal Shock Chamber / High-Temperature Test Chamber
Thermal Shock Condition 55°C × 0.5 h / −20°C × 0.5 h — 50 cycles total
High-Temperature Condition 40°C × 2 h
Laboratory Temperature 22°C
Laboratory Humidity 55% RH

Test Procedure

  1. Pre-test: Record ambient conditions (22°C, 55% RH). Inspect and document the appearance and electrical performance of both EV3 samples as a baseline. Photograph samples in their initial placement configuration.
  2. Thermal Shock Cycling: Place samples in the thermal shock chamber. Run 50 cycles of 55°C × 0.5 h followed by −20°C × 0.5 h with automated chamber program control (Program Control Charts 1, 2, and 3).
  3. High-Temperature Storage: Transfer samples to the high-temperature test chamber and expose to 40°C for 2 continuous hours.
  4. Post-test Inspection: Remove samples and perform visual inspection — check for deformation, wrinkling, cracking, or structural loosening. Conduct functional electrical performance test. Photograph post-test appearance and functional test setup.
  5. Acceptance Criteria: After testing, sample appearance must show no deformation or wrinkling; all structural components must remain tightly connected; electrical performance must be normal.

Test Data & Results

Characteristic Result
Electrical Specification (电气特性) OK
Structural Feature (结构特性) OK

Test Pictures: The following image sets were captured during and after testing:

  • Pre-test baseline photograph
  • Sample placement photograph
  • Program Control Chart 1
  • Program Control Chart 2
  • Program Control Chart 3
  • Post-test appearance photograph
  • Post-test functional test photograph

Observations: After 55 cold and hot cycle impact tests and high-temperature storage tests, there was no deformation or wrinkling in the appearance of the 2 PCS samples, and the connections of each structural component were compact. Electrical performance is normal.

Frequently Asked Questions

What does the ETENWOLF EV3 thermal shock test involve?

The EV3 thermal shock test cycles the unit between 55°C and −20°C in 30-minute intervals for 50 complete cycles, then follows with a 2-hour soak at 40°C. This simulates extreme real-world temperature swings to verify that the inflator’s housing, components, and electrical systems remain fully functional.

Did the EV3 pass the thermal shock and high-temperature test?

Yes. Both EV3 samples passed all test criteria. After 55 cold-and-hot cycle impacts and high-temperature storage, the units showed no deformation or wrinkling, all structural components remained tightly connected, and electrical performance was confirmed normal.

What acceptance criteria apply to this environmental test?

The sample appearance must show no deformation or wrinkling after testing; all structural parts must remain tightly and securely connected; and all electrical functions must operate normally. The EV3 met all three criteria and was judged Pass.

Who conducted the EV3 thermal shock test?

The test was conducted by Su Yimei at the BTK laboratory between 14 April 2025 and 17 April 2025, under report number 2025041701 on form BTK-R-Q-087A/1.
