This European standard specifies a method for sampling of screed materials, making and curing of specimens for subsequent testing. This method applies to dry material (bagged or bulk) or to freshly mixed screed materials (ready mixed or site mixed) or to products supplied in pre-packaged form or in packs ready for mixing. This standard applies to: samples of pre-packaged screed materials taken by the manufacturer during production and/or before dispatch, by the contractor or client before or during the period of use and subsequently in cases of dispute by any interested party and samples of the fully mixed product before laying. This method applies to mortars of cementitious-, calcium sulphate-, magnesite- and synthetic resin screed material. For mastic asphalt screed material see prEN 12697-20 and prEN 12697-21. Some methods according to manufacturers instructions may be necessary for special synthetic resin screed material.
