This document specifies a method used for the determination of the temperature of deflection under load of specified plastics (including fibre-reinforced plastics in which the fibre length is, prior to processing, greater than 7,5 mm) under defined conditions. A number of different test conditions are defined, depending on the anticipated specimen dimensions.
For additional information, see ISO 75‑1:2020, Clause 1.
