ASTM D638 Testing — Laboratories & Overview
ASTM D638 is the widely referenced ASTM test method for the tensile properties of unreinforced and reinforced plastics using dumbbell-shaped specimens.
When is it used?
- Resin and compound qualification or comparison
- Incoming material conformance for plastic parts
- Design data for injection moulded and machined plastics
- Supporting polymer failure investigations
Sample considerations
- Specimen type depends on material thickness and form.
- Conditioning and test speed are defined by the method and should be stated on the report.
