Test Methods: ASTM D1894 and ISO 8295

ASTM D1894

ASTM D1894 is a standard test method for measuring the CoF of plastic film and sheeting. It provides a consistent methodology for ensuring comparability of results across different laboratories and industries.

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.

Testing Procedures

Calibration
- Ensure the equipment is calibrated according to the manufacturer’s instructions.
Sample Preparation
- Cut samples to standard sizes and condition them at 23°C and 50% relative humidity for at least 48 hours.
Testing
- Secure the sample on the test sled and the counterpart material on the test bed. Initiate the test by moving the sled at a constant speed and record the static and kinetic friction forces.
Data Analysis
- Analyze the results using the provided software to determine the CoF values.

Applications and Industry Use Cases

Packaging Materials
- CoF testing ensures that packaging materials do not stick together excessively or slide apart too easily, affecting the integrity and usability of packaging.
Medical and Pharmaceutical
- For medical devices and pharmaceutical packaging, controlling the CoF is vital to ensure safety, functionality, and compliance with regulatory standards.
Textiles and Adhesives
- In textiles, the CoF affects fabric hand feel and performance. For adhesives, it determines bonding strength and ease of application.
