It s been an old standby for some people and can sometimes provide useful information.
Astm plastic sheet test.
One such test is the plastic sheet test astm d4263.
During processing these synthetic or semisynthetic organic solids have a very malleable characteristic that allows them to be molded into an assortment of shapes making them very suitable for the manufacture of various industrial products.
Astm d4263 the test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.
E252 test method for thickness of foil thin sheet and film by mass measurement d6988 guide for determination of thickness of plastic film test specimens.
Afterward the underside of the sheet is examined for signs of moisture.
1 1this test method 2 covers the determination of the tear resistance of flexible plastic film and sheeting at very low rates of loading 51 mm 2 in min.
This means no numbers or data just simple observation or eyeballing of the test location and testing materials for signs of excessive moisture.
And is designed to measure the force to initiate tearing.
It is critical that plastics manufacturers and packaging companies obtain an accurate mechanical profile of the plastic films they are producing to ensure that they meet the required expectations.
However it is not recommended.
Astm d 1894 01 testing standard test method for static and kinetic coefficients of friction of plastic film and sheeting this test procedure outlines the determination of the coefficients of sliding and starting friction of plastic sheeting and film when sliding over it or other substances at specific test conditions.
An overview of astm standards for measuring plastic film thickness regarding measuring plastic film thickness there are three main astm standards to consider.
If your sample is a sheet or film less than 1 00 mm thick it should be tested to astm d882.
Astm d638 only applies to rigid plastic samples between 1 00 mm and 14 mm in thickness.
There are many different test methods for various types of plastics.
