 Le présent document spécifie une méthode de détermination du fluage en flexion des plastiques sous forme d’éprouvettes normalisées dans des conditions spécifiées, telles qu’en matière de traitement préalable, de température et d’humidité. Cette méthode s’applique uniquement aux poutres simples, supportées sans contrainte et chargées au milieu de leur portée (méthode de mise en charge en trois…

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).  The method is suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-…

This document specifies a method of assessing the spectral quality of the irradiance provided by a daylight simulator to be used for visual appraisal of colours or for colour measurements and a method of assigning a quality grade to the simulator. It specifies the maximum permissible deviation of the chromaticity of the simulator from the chromaticity of the CIE standard daylight illuminant or…
