ABSTRACT

For a particular series of tests only one of the types of measuring points described in 3.4 shall be used. The type of measuring point employed shall be reported.

Report the difference between the first reference measurement and the final constant length, expressed as promille (mm/m) of the initial length of the specimen, as the shrinkage during curing or report the difference between the mean length at 60% R.H. and the length under the two conditions of humidity as:

(i) the contraction due to conditioning at 20°C and 40%R.H. (ii) the expansion due to conditioning at 20°C and 80%R.H. (iii) moisture content of the specimens in % of their dry weight after conditioning

at the relevant R.H. and the final moisture content.
