Description of 21/30423503 DC 2021This document specifies the reference method for the examination of coarse recycled aggregates for the purpose of identifying and estimating the relative proportions of constituent materials. The reference method is used for type testing and in case of dispute. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. This method does not apply to lightweight aggregates covered by the EN 13055 series. Annex A specifies an additive to the test procedure in Clause 7. It is suitable for test portions with low proportions of floating particles and is aimed at determining the proportion of floating particles with a higher precision level. Annex B provides an example of a test data sheet. Annex C specifies a procedure for testing a 4/63 mm fraction. Annex D specifies a method where the content of floating particles is estimated on a visual basis, after the visual sorting, without the immersing procedure in 7.2. Annex E describes an additive to the test procedure in order to separate floating particles into organic and inorganic. Annexes A, B, C, D and E are informative.
