Standard Test Method for Tensile Properties of Plastics
|Publication Date:||30 July 1982|
|ICS Code (Plastics in general):||83.080.01|
This method covers the determination of the tensile properties of plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pretreatment, temperature, humidity, and testing machine speed.
This method can be used for testing materials of any thickness up to 14 mm (0.55 in.). However, for testing specimens in the form of thin sheeting, including film less than 1.0 mm (0.04 in.) in thickness ASTM Method D 882, Test for Tensile Properties of Thin Plastic Sheeting,2 is the preferred method. Materials with a thickness greater than 14 mm (0.55 in.) must be reduced by machining.
NOTE 1-A complete metric companion to Method D 638 has been developed-D 638 M.
NOTE 2-This method is not intended to cover precise physical
procedures. It is recognized that the
NOTE 3-This method may be used for testing phenolic molded resin or laminated materials. However, where these materials are used as electrical insulation, such materials should be tested in accordance with ASTM Method D 229, Testing Rigid Sheet and Plate Materials Used for Electrical Insulation,2 and ASTM Method D 651, Test for Tensile Strength of Molded Electrical Insulating Materials.3
