Astm Plastic Sheet Test

An overview of astm standards for measuring plastic film thickness regarding measuring plastic film thickness there are three main astm standards to consider.

Astm plastic sheet test.

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. 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. However it is not recommended. Astm d882 is a common testing standard that is used to determine the tensile properties of thin plastic films and is commonly used for in line quality control purposes.

It s been an old standby for some people and can sometimes provide useful information. Astm d638 only applies to rigid plastic samples between 1 00 mm and 14 mm in thickness. Afterward the underside of the sheet is examined for signs of moisture. One such test is the plastic sheet test astm d4263.

If your sample is a sheet or film less than 1 00 mm thick it should be tested to astm d882. There are many different test methods for various types of plastics. Astm s plastics standards are instrumental in specifying testing and assessing the physical mechanical and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives. This means no numbers or data just simple observation or eyeballing of the test location and testing materials for signs of excessive moisture.

Astm d4263 the test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours. And is designed to measure the force to initiate tearing. 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.
