Abstract

This document specifies the reference method used for type testing and in case of dispute, for determination of the particle size distribution of aggregates, by washing and dry sieving. 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 document applies to all aggregates, with an upper aggregate size D up to 90 mm, but excluding added filler aggregates. NOTE The determination of the grading of fillers is specified in EN 933-10 [1]. Annex A specifies a test method for aggregates unsuitable for oven-drying. Annex B specifies additional steps for preparation of the test portion for all-in aggregates with D ≥ 31,5 mm, without washing size fractions greater than 16 mm. Annex C provides guidance for maximum mass on sieves to avoid overloading. Annex D provides an example of test data sheet. Annex E provides a sheet for graphical presentation of test results. Annex F gives precision data. Annex A is normative and Annexes B, C, D, E and F are informative.
