10 Mistakes to Avoid in Rubbing Fastness Testing

 

1. Not operating according to standards: Make sure to follow relevant testing standards and guidelines. Improper handling may result in inaccurate or incomparable test results.

 

2. Selecting the wrong sample: Selecting a sample that does not match the actual use may result in inconsistent test results. Make sure to select the proper specimen for accurate test results.

 

3. Neglecting Specimen Preparation: Specimen preparation includes proper cleaning, handling, and fixation. Neglecting these steps may affect the accuracy of test results.

 

4. Wrong choice of rubbing head: Different rubbing heads are suitable for different types of materials and applications. Selecting the wrong friction head may distort the test results.

 

5. Excessive pressure: Excessive pressure may cause damage to the specimen or produce false test results. Make sure to test to the pressure specified by the standard.

 

6. Friction cycle error: The friction cycle refers to the number of reciprocating motions exerted by the friction head on the sample. Wrong choice of rubbing cycle may lead to errors in test results.

 

7. Ignoring environmental conditions: Environmental conditions such as temperature and humidity for crockfastness testing may affect test results. Make sure to test under the specified environmental conditions.

 

8. Neglect of Calibration: Failure to calibrate test equipment on a regular basis can lead to inaccurate test results. Make sure to follow the manufacturer's recommendations for periodic calibration of equipment.

 

9. No repeated testing: repeated testing is to verify the reliability and consistency of test results. Failure to repeat testing may lead to misinterpretation or unreliability of results.

 

10. Do not record and analyze results: record test conditions and results for subsequent analysis and reference. Failure to record results may result in information being lost or untraceable.

 

Avoiding these mistakes will help to obtain accurate and reliable crockfastness test results and ensure the validity and comparability of the tests. Always refer to relevant standards and guidelines, and consult a professional tester or manufacturer if required.
