ASTM D1894 PDF

This standard is issued under the fixed designation D ; the number immediately 1 This test method is under the jurisdiction of ASTM Committee D20 on. ASTM D is a testing standard designed to measure the friction of plastic film and sheeting. The ASTM D standard test method is used to determine the kinetic (moving) and static (starting) resistance of one surface being dragged.

ASTM D1894-14 Coefficient of Friction of Plastic Film

The kinetic coefficient of friction is equal to the average force reading obtained during uniform sliding of the surfaces divided by the sled weight. Historical Version s – view previous versions of standard Translated Version s: Bluehill LE for Basic Testing. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. These methods yield empirical data for control purposes in film production.

Some of them bloom, or exude to the surface, lubricating it and making it more slippery. The coefficients of friction are related to the slip properties of plastic films that are of wide interest in packaging applications.

Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social d18944 standards for virtually any market around the world. Assurance Testing Inspection Certification. The static coefficient of friction is equal to the initial force scale reading divided by the sled weight.

ASTM D is a test method to determine static and kinetic coefficients of friction of plastic film and sheeting. Low force measurement Data rate used to capture peaks and troughs Reporting calculations in compliance with the standard Instron’s Solution: Software for Series Systems.

Inspection Validating the specifications, value and safety of your raw materials, products and assets. Therefore, it is advisable to refer to that material specification before using this test method. Need help or have a question? Because this blooming action may not always be uniform on all areas of the film surface, values from these tests may be limited in reproducibility.
