ASTM D647-88a PDF

Scope: 1.1 This practice covers the design of molds for test specimens of plastic materials. Designs are shown for compression molds (Figs. 1-4), a transfer mold (Fig. 5) for use in producing bar, disk, and tensile test specimensin thermosetting plastic materiais primarily, and an injection mold (Fig. 5) for use in producing bar, disk, and tensile test specimens in either thermoplastic or thermosetting materials. The plastic and mold temperatures, pressure and cycle timing used for the molding material should conform to the appropriate molding practice, if available, or to the material specification.Ifsuch information is not available,the recommendations of the material supplier should be followed, 1.2 Designs shown have been found suitable for a broad range of plastics but may not be optimum for any given materiai. Only the specimen dimensions are actually standardized? 1.3 The values stated in SIunits are to be regarded as the standard. The values in parentheses are given for information only. 1.4 Thisstandard may involve hazardousmaterials, operations, and eqirbment. This standard does not purport to addressall ofthe safetyprobletnsassociated with its use.It is the responsibility of the user of this standard to establish appropriate safty and health practices and determine the applicabilityof regulatorylimitationsprior to use.
