significance And Use:

scope:

1.1 This practice covers the general principles to be followed when compression molding test specimens of thermosetting molding compounds, such as phenolics, aminoplastics, melamine phenolics, epoxies, and unsaturated polyesters.

Note 1-This standard is similar in content (but not technically equivalent) to ISO 295-1974 (E).

1.2 Molding conditions are given for amino, phenolic, and allyl molding compounds. Materials specification standards should always be consulted to determine whether the material to be molded has any special requirements.

1.3 The values stated in SI units are to be regarded as standard. The values in brackets are given for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
