ASTM D5083-17Standard Test Method for Tensile Properties of Reinforced Thermosetting Plastics Using Straight-Sided Specimens
ASTM D5083 is a test method for measuring the force required to break a reinforced thermoset plastic specimen and the extent to which the specimen stretches or elongates to that breaking point.
Before conducting ASTM D5083, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
