Hdt temperature
WebTemperatura de deflexión por calor (HDT) (ASTM D 648, ISO 75-1 y 75-2) La temperatura de deflexión por calor se define como la temperatura a la que una barra de prueba estándar (5 × 1/2 × 1/4 pulg.) desvía 0.010 pulg. bajo una carga establecida de 66 o 264 psi. La prueba de temperatura de deflexión por calor, también conocida como ... Web1.1 This document gives a general test method 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. 1.2 ISO 75-2 gives specific requirements for plastics (including filled plastics and fibre …
