ASTM D1894 塑料薄膜与薄片的静态和动态摩擦系数

ASTM D1894

ASTM D1894 is a standardized test method used for determining static (μ_s ) and kinetic (μ_k ) coefficients of friction of plastic film and sheeting. Plastic film is a widely used material in the packaging industry and includes many types of food packaging (produce bags, carton liners, meat seal wrap) and non-food packaging (envelope liners, potting soil sacks). Plastic films are also key components of more complex products, such as electric vehicle batteries. In order to ensure that they perform as expected for the end user, the frictional properties of these films must be characterized and controlled.

ASTM D1894 coefficient of friction films
How to Perform a Test to ASTM D1894

This test requires the use of Instron's 2810-005 Coefficient of Friction fixture, which is specifically designed to meet the requirements of ASTM D1895 and ISO 8295. The film under test is secured on a flat surface and a sled of known weight is wrapped in the same material. The motion of the crosshead drags the sled along the film being tested and the force measured is used to determine both the static and kinetic coefficients of friction. Complete details on how to perform this test can be found by reading the full  ASTM D1894 standard.

Tips and Tricks
  • Instron’s 6800 controller can accurately measure forces down to 0.1% (1/1000th) of the 2580 series load cell's capacity, enabling the measurement of very low forces and potentially eliminating the need for multiple load cells. The lowest capacity 2580 series load cell is 500 N, meaning it can maintain 1% accuracy from 0.5 N to 500 N. Instron’s 2530 series load cells can maintain 1% accuracy down to 1/250th of the cell’s capacity when used on a 6800 frame. The lowest capacity 2530 series load cell is 5 N, meaning it can maintain 1% accuracy from 0.02 N to 5 N. Forces beneath the lower limits of the 2580 and 2530 series cells can be measured, but Instron cannot guarantee 1% accuracy.
  • Instron's Bluehill Universal testing software has advance pre-built methods available for ASTM D1894 to ensure that your test speeds and calculations are compliant.
