scope:

This International Standard specifies two methods for determining the "melting point" of polyamides. The melting point "is an arbitrarily determined temperature which, in fact, lies in a range of temperature which, for the homopolymers, covers a few degrees only. The determination of the "melting point" however, is useful for the characterization of polyamide homopolymers. It is of less use for copolymers, which may have a much wider melting range. The two methods of test described in this International Standard give results in close agreement in any one test, and quite good agreement between the two methods. Methods different from the two described in this document may give very different results.
