Test Equipment & Setup

Item Detail
Instrument Name Constant Temperature and Humidity Testing Machine (恒温恒湿试验机)
High Temperature Condition 60°C for 72 hours
Low Temperature Condition −20°C for 72 hours
Total Storage Duration 144 hours (combined high + low temperature)
Recovery Period Between Stages 4 hours at ambient temperature after high-temperature stage before low-temperature stage
Laboratory Temperature 24°C
Laboratory Humidity 45% RH

Test Procedure

  1. Pre-test: Confirm laboratory environment at 24°C and 45% RH. Prepare 6 pcs of the X5PRO inflation pump samples. Verify the constant temperature and humidity testing machine is calibrated and operational.
  2. High-temperature storage: Place all 6 samples inside the testing chamber. Set chamber to 60°C. Maintain for 72 continuous hours.
  3. Recovery period: Remove samples from the high-temperature chamber. Allow samples to rest at ambient room temperature (24°C) for 4 hours.
  4. Low-temperature storage: Transfer samples to the testing chamber set to −20°C. Maintain for 72 continuous hours. Total combined storage time: 144 hours.
  5. Post-test inspection: Remove samples from the low-temperature chamber. Inspect each unit visually for battery swelling (鼓包) or physical deformation. Power on each unit and verify normal startup and operation.
  6. Acceptance criteria: All units must power on and start normally; no battery swelling is permitted on any sample.

Test Data & Results

Test Stage Condition Duration Observation
High Temperature Storage 60°C 72 hours Samples stored in constant temperature and humidity chamber (program-controlled)
Recovery (Ambient) 24°C room temperature 4 hours Samples allowed to equilibrate before low-temperature stage
Low Temperature Storage −20°C 72 hours Samples stored in constant temperature and humidity chamber (program-controlled)
Post-test Functional Check Ambient (24°C, 45% RH) After 144 h total All units powered on and started normally; no battery swelling observed

Observations: After completing high and low temperature storage, the complete units were able to power on and start normally. Battery samples showed no swelling. Visual inspection confirmed no physical abnormalities on any of the 6 samples.

Frequently Asked Questions

What does the high and low temperature storage test evaluate?

The test evaluates the durability of the X5PRO inflation pump when stored in extreme temperature environments. It simulates real-world scenarios where a product may be left in a hot vehicle in summer or exposed to freezing conditions in winter, verifying that the unit and its battery remain functional and safe after such exposure.

Why is there a 4-hour ambient recovery period between the two temperature stages?

The recovery period allows thermal stresses from the high-temperature stage to dissipate before the sample is subjected to sub-zero conditions. Transitioning directly between extreme temperatures without recovery could introduce condensation or thermal shock effects that do not reflect typical real-world storage patterns, potentially skewing test results.

What is the acceptance criterion for this test?

All samples must power on and operate normally after the full 144-hour storage cycle. In addition, no battery swelling (鼓包) is permitted on any unit. Both conditions must be met for a PASS verdict.

What does a PASS result mean for the X5PRO?

A PASS confirms that the X5PRO inflation pump can withstand storage at 60°C for 72 hours and −20°C for 72 hours without functional degradation or battery safety issues. This is a new-product qualification milestone, indicating the design is suitable for markets or distribution environments with wide ambient temperature ranges.
