Test Equipment & Setup

Item	Detail
Instrument Name	Single-arm drop testing machine (单臂跌落试验机)
Drop Height	100 cm
Number of Drops	6 faces — 6 drops total
Sample Weight	Not recorded in report
Test Class / Level	Not specified
Acceptance Criteria	Product appearance and function normal; housing must show no cracking

Test Procedure

Pre-test: Record laboratory environment — temperature 22 °C, humidity 55 % RH. Confirm sample quantity (3 PCS) and weigh samples. Inspect initial appearance and verify power-on function.
Setup: Mount sample on single-arm drop testing machine. Set drop height to 100 cm.
Drop Sequence: Execute 6 consecutive drops, one per face (Face 1 → Face 2 → Face 3 → Face 4 → Face 5 → Face 6), following the standard 6-face drop sequence.
Post-drop inspection (after all 6 drops): Power on the unit and verify normal operation. Visually inspect housing for cracks or deformation. Disassemble unit and inspect cylinder mounting ribs for fractures.
Acceptance Criteria: Product appearance and function normal after drop; housing shows no cracking; cylinder mounting ribs show no fracture.

Test Data & Results

Drop No.	Drop Face	Drop Height	Post-Drop Power-On	Housing Crack	Cylinder Rib Fracture	Observation
1	Face 1	100 cm	Normal	None	None	Normal after drop
2	Face 2	100 cm	Normal	None	None	Normal after drop
3	Face 3	100 cm	Normal	None	None	Normal after drop
4	Face 4	100 cm	Normal	None	None	Normal after drop
5	Face 5	100 cm	Normal	None	None	Normal after drop
6	Face 6	100 cm	Normal	None	None	Normal after drop

Test Result Summary (from report): Samples passed the 100 cm drop test. Power-on function was normal after drops. Housing showed no cracking. Upon disassembly, cylinder mounting rib positions showed no fracture.

Photo Record Notes (as documented): Pre-drop photos captured alongside the single-arm drop testing machine and power controller. Six sequential drop photos recorded (Drop 1 through Drop 6). Post-drop photos confirmed normal power-on and intact cylinder mounting ribs.

Frequently Asked Questions

What does a "Reference" verdict mean in this drop test?

The report marks the result as "Reference" (参考) rather than a binary Pass/Fail. This classification is typically used for new product evaluation data that serves as a baseline reference for future engineering decisions, rather than a formal compliance pass against a published standard. All physical observations were positive.

Why were 6 drop faces used instead of fewer?

The 6-face drop sequence covers all orthogonal orientations of a rectangular product — top, bottom, front, back, left, and right. This ensures every structural surface and internal mounting point is subjected to impact loading, providing a comprehensive mechanical reliability assessment.

What internal component was specifically inspected after disassembly?

The cylinder mounting rib positions (气缸固定筋脚位) were specifically examined for fractures. These plastic ribs secure the air cylinder inside the housing and are a known stress concentration point during drop events. No fractures were found on any of the 3 samples.

What are the environmental conditions required for this test?

The test was conducted at 22 °C and 55 % RH. These conditions represent standard indoor ambient conditions. Extreme temperature or humidity conditions outside this range could affect material brittleness and impact resistance, which would require separate testing.
