This European Standard specifies procedures for the chemical analysis of aggregates. It specifies the
reference procedures and, in certain cases, an alternative method which can be considered as giving
equivalent results.
Unless otherwise stated, the test methods specified in this standard may be used for factory production
control, for audit tests or for type tests.
This standard describes the reference methods used for type testing and in cases of dispute (and
alternatives methods) for chemical analyses of aggregates. For the purpose of type testing and in cases
of dispute only the reference method should be used. For other purposes, in particular factory
production control, other methods may be used provided that an appropriate working relationship with
the reference method has been established.
