Test Overview

Field	Details
Test Type	Reliability Test (Mechanical Life)
Test Standard	Internal Control Standard — ensure no functional failure, verify stability and reliability
Report No.	2025042801.0
Test Date	2025-04-19 to 2025-04-28
Product No. / Name	B7 Balloon Pump (P400)
Type Specification	B7
Manufacturer	ETENWOLF
Sample Quantity / ID	3 PCS — C0419-1#, C0419-2#, C0419-3#
Test Purpose	Evaluate whether the life test affects normal functional operation of the sample
Test Environment	Room Temperature: 23 °C, Humidity: 60%, Power Source: 120 V

Test Equipment & Setup

Item	Details
Test Equipment	Test Fixture / Jig (测试架); Variable-Frequency Power Supply (变频电源)
Number of Nozzles in Use	2 (both large and small nozzle attachments fitted during run)
Power Source Voltage	120 V AC
Ambient Temperature	23 °C
Relative Humidity	60 %
Required Run Duration	100 hours continuous
Operation Mode	Continuous energized operation (持续通电运行)

Test Procedure

Pre-test: Mount each sample on the test fixture with both nozzle attachments (large and small) installed. Verify power supply is set to 120 V AC and ambient conditions are 23 °C / 60 % RH.
Start: Energize all three samples simultaneously and begin logging run time.
During test: Monitor samples continuously for abnormal noise, air-pressure deviation, overheating, or any functional anomaly. Record observations at checkpoints.
Duration: Maintain continuous operation for a total of 100 hours per sample.
Post-test: Power off samples. Inspect appearance and functional performance. Verify air pressure on both large and small nozzle outlets.
Acceptance Criteria: No functional failure; performance must remain stable; air pressure on both nozzle sizes must be normal; no abnormal noise or other anomalies throughout the 100-hour run.

Test Data & Results

Sample ID	Test Duration (Hours)	Issue Description / Observations
C0419-1#	100.0	No abnormal noise during operation; performance basically stable; capable of continuous operation; air pressure normal; no other abnormal phenomena.
C0419-2#	100.0	No abnormal noise during operation; performance basically stable; capable of continuous operation; air pressure normal; no other abnormal phenomena.
C0419-3#	100.0	No abnormal noise during operation; performance basically stable; capable of continuous operation; air pressure normal; no other abnormal phenomena.

Test Picture Phases Noted: Pre-test inspection, mid-test monitoring, and post-test verification (large and small nozzle air pressure confirmed normal).

Overall Assessment: After completing the 100-hour operational life test, all B7 balloon pump samples showed no abnormality in appearance or function. Air pressure on both large and small nozzles was normal. Test result: OK.

Frequently Asked Questions

What does the 100-hour life test actually verify?

The test simulates extended continuous use to confirm that the P400 balloon pump maintains stable air pressure on both nozzle sizes, generates no abnormal noise, and suffers no functional failure over a prolonged operational period. It validates the pump’s mechanical reliability under real-world duty cycles.

What power supply was used, and does it affect results for other markets?

The test was conducted at 120 V AC, which reflects North American mains voltage. If the P400 is deployed in 220–240 V markets, a separate life test at the relevant input voltage would be needed to confirm equivalent reliability under those conditions.

Were both nozzle sizes (large and small) tested simultaneously?

Yes. Both nozzle attachments were fitted to each sample for the entire 100-hour run. Post-test air-pressure checks confirmed normal output on both nozzle sizes for all three units.

What is the internal control standard referenced in this report?

ETENWOLF’s internal control standard for reliability testing requires that no functional failure occurs during the prescribed run duration, and that the unit demonstrates stable, consistent performance throughout. It is defined and maintained internally rather than referencing a published external standard such as IEC or UL.
