标准摘要
[中文适用范围]： 1.1 This document specifies a method for determining the flexural creep of plastics in the form of standard test specimens under specified conditions such as those of pre-treatment, temperature and humidity. It is only applicable to a simple freely supported beam loaded at mid-span (three-point-loading test). 1.2 The method is suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-reinforced plastics materials (see ISO 472 for definitions) test specimens moulded directly or machined from sheets or moulded articles. NOTE The method can be unsuitable for certain fibre-reinforced materials due to differences in fibre orientation. 1.3 The method is intended to provide data for engineering-design, quality control, research and development purposes. 1.4 The method might not be applicable for determining the flexural creep of rigid cellular plastics (attention is drawn in this respect to ISO 1209-1 and ISO 1209-2).
