NOTE The apparatus required depends upon the method selected for determining the volume of theĥ Test specimens The minimum volume of a specimen shall be 0,785 I. The tank should be of sufficient size to allow the specimen to be fully immersed.Ĥ.4 Ventilated oven, in which the temperature is capable of being controlled at (105 ± 5) ☌.
Lithe reading of the balance is affected to within the accuracy required due to the displacement of water when immersing the specimen, then the tank should be fitted with a device to maintain the water at a constant level. ISO Online browsing platform: available at 4 ApparatusĤ.1 Calllpers and rules, with a maximum permissible error of 0,5 % of the dimension, for measuring the dimensions of the specimens.Ĥ.2 Balance, equipped with a stirrup for weighing the specimen in both air and water with a maximum permissible error of 0,1 g of the mass.Ĥ.3 Water tank, fitted with a device to maintain the water at a constant level and of sufficient size to allow the specimen on the stirrup to be fully immersed to a constant depth (see Figure 1). ISO and JEC maintain terminological databases for use in standardization at the following addresses:
