Astm Plastic Sheet Test

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.

Astm plastic sheet test. Astm d4263 the test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours. However it is not recommended. And is designed to measure the force to initiate tearing. 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.

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. The specimen geometry of this test method produces a stress concentration in a small area of the specimen. 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. 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. 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. One such test is the plastic sheet test astm d4263.

There are many different test methods for various types of plastics. Afterward the underside of the sheet is examined for signs of moisture. 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.
