The TR will be structured to support both parts 1 and 2 of prEN 17555. Part 1 will provide information that can be used to form normative clauses. The information in part 2 will be complementary and non-contradictory to support the practical application of part 1. The information will be in the form of supporting clauses and an informative annex that will include advice on reasons for testing, test method selection, test method conditions (e.g. final liquid to solid ratio) and declaring release of RDS.
It is anticipated that the information will be transposed for other aggregate standards.
The TR will be based on CEN prEN 13637-1 on how to choose and implement prEN 13637 -2 and -3 leaching test methods, as appropriate, and associated analytical methods into the standard.
