Test principle
The volume and weight changes which occur during air drying and water storage,from 24 h after casting and
onwards,are measured on prismatic specimens having dimensions of 5 mm x 40 mm x 160 mm.
Apparatus
1
5.1 Moulds complying with the requirements of 4.5 of EN 196-1:1994.
5.2 Apparatus for measuring the dimensions of the test specimens to an accuracy of 0,1 mm.
5.3 Balance capable of weighing 500 g to an accuracy of 0,01 g.
5.4 Water bath containing potable water for completely immersing the test specimens at a temperature of
(21±2) ℃ The volume of the water bath is chosen to comply with requirements in 7.3.4.
5.5 Storage room for conditioning the test specimens,at a temperature of(21±2)°Candarelative
humidity of (60±10) %.
5.6
Support grid for supporting the specimens with a minimum of 5 mm clearance in a water bath or in air.
5.7 Air oven capable of maintaining the specified temperature to ±2 ℃. The oven shall be fitted with
forced-ventilation equipment
