Interpretation Introduction
Interpretation:
Two international technical societies which are responsible for the development of the standards and specifications to test plastics are to be named.
Concept Introduction:
In plastic industries, most of the segments are dependent on the test data of the plastics for the direction of their activities. The manufacturers of the raw-materials use these testing and its data to maintain the control of the processes and characteristics of their products. Based on the standard tests, the selection of the plastics is done by the designers for any new products to be produced.
Testing leads to the thorough understanding of the plastics in the industry which are essential.Expert Solution & Answer
