How to Use Rub Resistance Tester

A rub resistance tester is a device used to measure the resistance of a material to abrasion or rubbing. The testing procedure for a rub resistance tester typically includes the following steps:

1. Sample preparation: The material being tested should be cleaned and free from any defects or damage. The sample should be representative of the actual material being used in production.
2. Setting up the tester: The rub resistance tester is set up according to the manufacturer’s instructions and the desired test conditions. This may include setting the number of rubs, the type of rubbing head, and the force applied.
3. Testing: The material sample is placed on the tester’s platform and the rubbing head is applied to the sample according to the desired test conditions. The rubbing head applies a specified force and rubs the sample a specified number of times.
4. Data collection: The results are recorded, including the number of rubs, the force applied, and any visual changes in the sample.
5. Analysis: The data is analyzed to determine the resistance of the material to abrasion or rubbing.
6. Evaluation: The results are evaluated against the standards and criteria for the specific application and industry.

It’s important to ensure that the rub resistance tester is properly calibrated and maintained before conducting the test. The sample preparation is also important, the material being tested should be free from any defects or damage to have accurate results.

It’s also worth noting that the rub resistance tester is specified in several standards such as ASTM D3884 and ISO 12947, and it’s important to follow these standards to ensure the comparability of the results.

It’s also worth noting that the results of the rub resistance test are often reported as the number of rubs required to produce a specified level of damage or visual change in the material, such as a change in gloss or color. It’s also important to note that the results of the rub resistance test can be affected by the temperature, humidity, and the test duration, so it’s important to maintain the same conditions when testing multiple samples to ensure the comparability of the results.
