Annex A (normative) - Testing for release of (regulated)
                      dangerous substances from pre-hardened
                      concrete products formed in the factory
Annex B (informative) - Testing for release of (regulated)
                        dangerous substances from hardened
                        test pieces representative of fresh
                        wet concretes or pre-packaged concretes

                        design to be applied for the assessment of
                        new/unapproved constituents of concrete
Bibliography

Describes three test methods: - The first is designed to test the constituents of concrete, not designated as WT products, using reference concrete matrices (control mixes and test mixes) wherein the release of (regulated) dangerous substances from the constituent under test, into soil, groundwater or surface water, can be determined. - The second method, in normative Annex A, is designed to test factory made concrete products, not designated as WT products, as either test pieces sawn or cored from pre-hardened monoliths or as standardsized moulded test pieces formed from proxy samples of fresh wet material taken from concrete used in the production of factory made items. - The third method, in informative Annex B, is designed to test concretes sampled in the fresh wet state or prepackaged state, not officially classified as WT products, as standard-sized moulded test pieces.
