1 Scope This Standard specifies four methods for the determination of the Vicat softening temperature (VST) of thermoplastic materials: Method A50 —— using a force of 10 N and a heating rate of 50 ℃/h Method B50 —— using a force of 50 N and a heating rate of 50 ℃/h Method A120 —— using a force of 10 N and a heating rate of 120 ℃/h Method B120 —— using a force of 50 N and a heating rate of 120 ℃/h The methods specified in this Standard are applicable only to thermoplastics, for which they give a measure of thetemperature at which the thermoplastics start to soften rapidly. 2 Normative References The following standards contain provisions which, through reference in this Standard, constitute provisions of this Standard. At the time of publication, all editions indicated are valid. All standards are subject to revision, and all parties coming to an agreement according to this standard are encouraged to study whether the latest editions of these documents are applicable.
