Test Results – Visual Inspection (Sample S-01)
Following the completion of all 10 drop sequences, the sample underwent a thorough visual inspection and functional verification. The results for sample S-01 (Inflator Pump – S7) were as follows:
- No damage to the internal sample was observed.
- No deformation of any component was detected.
- No parts shedding, loosening, or detachment occurred.
- No cracking of the housing or structural elements was found.
- Startup (power-on) function operated normally after testing.
- Charging function operated normally after testing.
The unit passed all evaluation criteria under visual inspection and functional check, demonstrating robust structural integrity and reliable operation following a 1000 mm free-fall drop test across all standard orientations.
Standards & Compliance
The drop test was performed in full accordance with the Chinese national packaging standard GB/T 4857.5-1992 — Packaging — Basic Tests for Transport Packages — Part 5: Vertical Drop Test Method. This standard defines the test procedures for evaluating the ability of a transport package and its contents to withstand vertical free-fall drops.
| Standard | Title | Scope |
|---|---|---|
| GB/T 4857.5-1992 | Packaging – Basic Tests for Transport Packages – Vertical Drop Test Method | Evaluates structural and functional integrity of packaged goods after free-fall drops from a specified height across multiple orientations |
Key compliance requirements addressed by this test include:
- Drop height: 1000 mm for a packaged unit weighing 4.20 kg, consistent with the standard’s weight-to-height mapping.
- Drop orientations: All mandatory positions — corner, edges, and faces — were covered across 10 sequences.
- Pass criteria: The test is passed if the measured result equals or is below (or above, as applicable) the defined limit. In the absence of explicit uncertainty provisions, the measured value alone determines pass/fail status.
- Instrument traceability: All test instruments are calibrated and traceable to national or international standards, in line with metrological requirements.
All instruments used in this test are calibrated with traceability to national or international standards. Further traceability information is available from Waltek HCT upon request.

Frequently Asked Questions
- Q: What does the drop test result mean for the ETENWOLF S7 tire inflator?
- A: The ETENWOLF Vortex S7 successfully passed all 10 sequences of the GB/T 4857.5-1992 drop test from a height of 1000 mm. After testing, the unit showed no damage, deformation, cracking, or loose parts, and both the power-on and charging functions operated normally. This confirms the product and its packaging provide reliable protection during transport and handling.
- Q: What standard governs this drop test, and why does it matter?
- A: The test was conducted under GB/T 4857.5-1992, the Chinese national standard for vertical drop testing of transport packages. This standard is widely used to validate that consumer electronics and packaged goods can survive the physical stresses of logistics, shipping, and retail handling without sustaining damage that would affect their usability or safety.
- Q: Who performed the drop test and is the laboratory accredited?
- A: The test was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., a third-party testing laboratory based in Shenzhen, China. The laboratory operates under the HCT testing group and uses calibrated instruments traceable to national and international standards.

- Q: Is this drop test report the same as a CE or UN38.3 certification?
- A: No. This report specifically covers drop test performance under GB/T 4857.5-1992 and evaluates packaging and structural integrity. It is separate from other certification types such as CE marking (which addresses EU market safety and EMC requirements) or UN38.3 (which governs lithium battery transport safety). The ETENWOLF Vortex S7 may hold additional certifications covering those separate requirements.
