PLASTICS – DETERMINATION OF TEMPERATURE OF DEFLECTION UNDER LOAD – PART 1: GENERAL TEST METHOD (FIRST REVISION) (ISO 75-1:2004, IDT)
This Malaysian Standard specifies methods for the determination of the temperature of deflection under load (flexural stress under three-point loading) of plastics. Different types of test specimen and different constant loads are defined to suit different types of material.
This Malaysian Standard gives a general test method, part 2 gives specific requirements for plastics (including filled plastics and fibre-reinforced plastics in which the fibre length, prior to processing, is up to 7,5 mm) and ebonite while part 3 gives specific requirements for high-strength thermosetting laminates and long-fibre-reinforced plastics in which the fibre length is greater than 7,5 mm.
This Malaysian Standard specified are suitable for assessing the relative behaviour of different types of material at elevated temperature under load at a specified rate of temperature increase. The results obtained do not necessarily represent maximum applicable temperatures, because in practice essential factors suc
