III. Test Methods
(1) Principles of CoF Testing
CoF testing involves measuring the frictional forces between two surfaces. This is typically divided into static friction (the force required to initiate movement) and kinetic friction (the force required to maintain movement). Proper sample preparation and conditioning are essential to ensure accurate and repeatable results.
(2) Sample Preparation and Conditioning
- Sample Size: Standard size is typically 63.5 mm x 63.5 mm(standard), but this can vary depending on the specific test requirements.
- Conditioning: Samples should be conditioned at 23°C and 50% relative humidity for at least 48 hours prior to testing.
(3) Testing Procedure
- Calibration: Ensure the equipment is calibrated according to the manufacturer’s instructions.
- Sample Placement: Secure the sample on the test sled and the counterpart material on the test bed.
- Testing: Initiate the test by moving the sled at a constant speed. Record the static and kinetic friction forces.
- Data Analysis: Analyze the results using the provided software to determine the CoF values.
IV. Standards for CoF Testing
(1) ASTM D1894
ASTM D1894 is a widely recognized standard for measuring the CoF of plastic film and sheeting. It provides a consistent methodology to ensure comparability of results across different laboratories and industries.
Detailed Test Method According to ASTM D1894:
- Sample Preparation: Samples are cut into strips and conditioned as specified.
- Test Setup: The film is placed on a horizontal plane while the sled, covered with the same or different material, is pulled across the plane at a constant speed.
- Measurements: The forces required to initiate and maintain movement are recorded to determine the static and kinetic CoF.
Requirements and Specifications:
- Equipment Calibration: Regular calibration is essential for accuracy.
- Test Speed: Typically set at 150 mm/min.
- Environmental Conditions: Testing should be conducted at controlled temperature and humidity levels.
(2) ISO 8295
ISO 8295 is an international standard for determining the CoF of plastic films and sheeting. It ensures uniform testing procedures and results consistency on a global scale.
Detailed Test Method According to ISO 8295:
- Sample Preparation: Similar to ASTM D1894, samples are prepared and conditioned.
- Test Setup: The sample is placed on a flat surface, and a sled with a specified weight is pulled across it at a constant speed.
- Measurements: Static and kinetic friction forces are measured to calculate the CoF.
Requirements and Specifications:
- Test Speed: Set between 100 to 300 mm/min, typically 100 mm/min.
- Sled Weight: Specified according to the standard.
- Environmental Conditions: Tests should be performed under controlled conditions to ensure repeatability.
