scope:

This Standard describes the procedures for the chemical analysis of cement. The Standard describes the reference procedures and, in certain cases, an alternative method which can be considered as giving equivalent results. If other methods are used it is necessary to show that they give results equivalent to those given by the reference methods. In the case of a dispute, only the reference procedures are used. This Standard applies to cements, and also to their constituent materials such as clinker and blastfurnace slag. Standard specifications state which methods to be used.
