Test Process
Fiber conductivity testing usually involves a series of steps to ensure that the fiber material meets the expected standards in terms of conductivity performance. The following is a general fiber conductivity testing process:
1Consultation and quotation: Contact the testing agency to explain the sample situation and test requirements.
2Send samples: Send the fiber samples to be tested to the laboratory.
3Confirm the test plan: Select the test method (two probes/four probes) and test conditions.
4Sample testing: The laboratory tests according to the standard.
5Issuance of report: Provide standardized test reports, including raw data, analysis results, charts.

How to Choose the Right Testing Service
- Clarify the purpose of the test: Is it scientific research verification, product quality control or patent application
- Look at the qualifications of the institution: Does it have CNAS or CMA certification
- Technical capabilities: Does it support the test method you need (such as four-probe)
- Report standards: Does it provide standard test reports (can be used for certification/publication)
- Price and cycle: Choose a cost-effective service based on the budget and project progress
Notes
- Maintain good contact between the electrode and the fiber to prevent false connection.
- Avoid bending and stretching of the fiber to affect the resistance value.
- Use a constant temperature environment to avoid the influence of temperature on resistance.
- Take the average value after multiple tests to improve accuracy.
Common Test Standards
Fiber conductivity test standards mainly involve evaluating the conductivity, conductive properties and wearing comfort of conductive fiber materials. The following are some common related standards:
- ASTM D4496: For the measurement of electrical resistance of conductively coated fabrics.
- ISO 3915: Standard for the measurement of electrical resistivity.
