A report saying 'passed' has limited value without knowing what was measured and how. Useful test evidence connects the result to the component, method and acceptance requirement.

Identify the tested item

The report should identify the component and relevant configuration, with serial or batch traceability where applicable. Confirm whether it covers your supplied item, a sample or a general type test. Those are different forms of evidence.

Specify the measurement conditions

Pressure, flow, fluid temperature and test duration can affect results. Ask for the applicable method, instrument information and acceptance limit. A leakage value without pressure and temperature conditions is difficult to compare with a requirement.

Review exceptions

Check whether any test was omitted, substituted or performed under different conditions. Resolve discrepancies before treating the report as acceptance evidence. Do not infer certifications, service life or application suitability from a limited functional test.

Practical checklist

• Connect the report to the correct item and configuration.
• Record method, conditions and acceptance limits.
• Review omissions and deviations explicitly.

Discuss your application

Explore related hydraulic products, or send JIUDING your model code and application details. Include the circuit drawing and the operating conditions relevant to the checks above so the required configuration can be reviewed.
