ASTM E23 methods describe notched-bar impact testing of metallic materials by the simple-beam test (Charpy) and the cantilever-beam test (Izod). This method gives the requirements for test specimen, procedure, reports, Charpy impact machine verification, determining the shear fracture appearance, etc. The values stated in SI units are regarded as standard.
Scope:
ASTM D1601 is used to determine the dilute solution viscosity of ethylene polymers at 135°C, and it presents problems not usually encountered in viscometry. It works with a wide range of ethylene polymers with densities ranging from 0.910 to 0.970 g/cm2. It is a valuable tool for characterizing ethylene polymers and their processing characteristics.
Procedure:
In ASTM E23, a suitable specimen (as the specimens of several different types are recognized), a set of anvils, and specimen supports on which the test specimen is placed to obtain the blow of the moving mass, a moving mass that has adequate energy to break the specimen placed in its pathway, and an indicating device for measuring the absorbed power of the broken specimen.
Specimen size
The sample’s length, width, and thickness should be 55 mm, 10 mm, and 10 mm, respectively.
Data:
The absorbed energy values above 80% of the range capacity are inaccurate and shall be reported as approximate.
A variety of microscopy and spectroscopy tools available for precise measurements from the nano to the meter scale.
