7.1 Conduct the test in air, in a heating oven at a temperature specified in the relevant specification, within a tolerance of +/-2 o C. The heating oven and test specimen support shall be maintanined at the test temperature for 24 h or until thermal equilibrium is reached, whichever occures sooner.
* ?1 G4 u8 f) X9 `) |When thermal equilibrium conditions are reached, place the test specimen on the approximate center of the test specimen support so that its upper surface is horizontal. Gently lower the pressure ball on to the appromate centre of the test specimen.
