PLASTICS – DETERMINATION OF TEMPERATURE OF DEFLECTION UNDER LOAD – PART 3: HIGH-STRENGTH THERMOSETTING LAMINATES AND LONG-FIBRE-REINFORCED PLASTICS (FIRST REVISION) (ISO 75-3:2004, IDT)
This Malaysian Standard specifies a method for the determination of the temperature of deflection under load of high-strength thermosetting laminates and compression-moulded long-fibre-reinforced plastics in which the fibre length is greater than 7.5 mm. The flexural stress used is not fixed, as in MS ISO 75-2, but is a fraction (1/1 000) of the initial (room-temperature) flexural modulus of the material under test. This allows the method to be applied to materials with a wide range of flexural moduli.
