CSN EN ISO 899-2

CSN EN ISO 899-2 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).
