Scope

This European Standard describes a simple method for the examination of coarse and all-in recycled aggregates for the purpose of identifying and estimating the relative proportions of constituent materials. This reference test method should be used for type testing and in case of dispute. 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.

NOTE 1 This method is not appropriate for lightweight aggregates covered by EN 13055 series.

NOTE 2 If dangerous substances are found in while carrying out this method, they should be dealt with in accordance with regulations in the place of use.

Purpose

Following the CEN enquiry in 2021, CEN TC 154/ SC 6/WG 2 was unable to address all 111 comments within the allotted timeframe. TC 154 therefore tasked SC 6 to complete the revision outside the scheduled timeframe and to submit a new draft to CEN for consultation once it is ready.
