What does the drop test for the X5 PRO evaluate?

The drop test evaluates the ability of the X5 PRO packaging and product to withstand impacts from a height of 1200 mm across 10 different orientations — including corners, edges, and all six faces — as specified by GB/T 4857.5-1992. It confirms that the product arrives intact and fully functional after normal shipping and handling stresses.

What was the outcome of the drop test?

The X5 PRO passed all 10 drop sequences. After testing, the packaging showed no cracking or damage, the product exterior was undamaged, and the unit powered on and functioned normally. The result is documented in report WTH25H12334291P, issued on 2025/12/25.

Which laboratory conducted the drop test?

The test was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an independent third-party testing laboratory in Shenzhen, China. The laboratory's equipment is calibrated and traceable to national and international standards.

Does this report serve as a public certification?

This report does not carry the CMA logo and is therefore intended for internal purposes such as product development, quality control, and research. It confirms drop test performance against GB/T 4857.5-1992 but does not constitute a regulatory certification for public market access on its own. For full regulatory compliance, refer to the product's broader certification portfolio.

Standards & Compliance

The free drop test was conducted in strict accordance with the Chinese national packaging standard GB/T 4857.5-1992 — Packaging — Basic tests for transport packages — Part 5: Free drop test method. This standard specifies the test procedures for evaluating the ability of a packaged product to withstand free drops from a defined height onto a rigid surface, covering corner, edge, and face impact orientations.

Standard	Scope	Applicability
GB/T 4857.5-1992	Free drop test for transport packages	Packaging integrity and product protection during handling and shipping

The evaluation rule applied states: if the measured outcome is equal to or below the defined limit (i.e., no cracking, damage, or functional failure), the test is passed, regardless of measurement uncertainty. If the outcome exceeds the limit, the test is not passed.

All calibration equipment used is traceable to national or international metrological standards. Further traceability information is available from Waltek HCT upon request.
