ASTM G143

ASTM G143 testing equipment is used to evaluate the friction behavior between a flexible web material and a cylindrical roller surface under controlled sliding conditions. The test simulates real-world web handling processes commonly found in converting, printing, coating, laminating, packaging, and material manufacturing operations where continuous materials travel over rollers.

A typical web roller coefficient of friction test measures both static and kinetic friction coefficients by recording the forces generated as a web specimen slides across a roller at a defined tension, wrap angle, and sliding speed.

Materials commonly evaluated include plastic films, paper and paperboard, metal foils, nonwoven materials, textiles, elastomers, coated substrates, and other flexible web products. Industries utilizing ASTM G143 testing include flexible packaging, paper converting, medical packaging, pharmaceutical packaging, electronics manufacturing, specialty coatings, and industrial textiles.

Cell Instruments provides material testing solutions suitable for ASTM G143 friction evaluation, including adaptable tensile-based platforms, customized fixtures, specialized roller assemblies, and application-specific testing configurations. These systems support quality control, product development, material comparison studies, and process optimization where web-to-roller friction performance is a critical parameter.
