The ASTMD638 is the perfect test to get quick properties to use in mechanical design of plastic parts. a) True b) - False

Answer: True

Explanation:

The ASTMD638 is the standard property for determining the tensile nature in the plastic parts and materials. It can be also used for testing the material thickness approximately 14mm.

ASTMD638 is the test method and it also determine the poisson's ratio. This method are also use to control the specification of the plastic materials.

ASTM stand for american society for testing and material and it include the specification of tensile strength and module.
