Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Management Centre or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and UnitedKingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

Length: 230 mm; width: 64 mm; thickness: 54 mm; Shape C:
Length: 230 mm; width: 64 mm; thickness: 64 mm. The width of the test piece as tested shall correspond to the height during preparation. The vibration of the testpiece during preparation shall be recorded, and for shape C the compaction surface shall be marked for reference.The selection of test pieces for each type of material shall be as given in Table 1, except that for basic densecastables and ramming materials, test pieces with a diameter of 50 mm and height of 50 mm ± 1 mm arepermissible. Shape C shall be used as the referee shape.SIST EN 1402-5:2004

a For these materials, shapes B and C are prepared by cutting from shape A. b Tests for which results are directly obtained from the bars without size modifications are modulus of rupture, coldcompressive strength, and permanent change in dimensions on heating.4 Apparatus4.1Separator A riffle sampler, suitable for use with the maximum particle size of the product, or a shovel for the quarteringmethod. The riffle separation shall be at least 2,5 times the maximum grain size.4.2Mixer4.2.1Pan See Figure 1. The pan shall be symmetrical around axis A and shall have a capacity of 15 l to 30 l. Both the panand the mixing blade (see 4.2.2) shall be constructed from a material that does not react with the test material. SIST EN 1402-5:2004

2453Figure 3 — Modification of sand-rammer for workability test4.6Power press A hydraulic type press shall be equipped with suitable moulds for forming test pieces of the required size. Thepress shall be capable of applying a minimum of 10 MPa pressure to the moulded face.NOTEThe power press should only be used for shaping test pieces from plastics.4.7Trowel Pointing type or stiff-bladed spatula shall have a typical size of 150 mm length and 50 mm width.4.8Moulds Moulds shall be capable of being dismantled and shall be watertight. They shall be made from a material that doesnot react with the material to be tested. For compaction by pneumatic rammer, the moulds shall be rigid so that they do not warp during ramming.NOTE 1Steel or similar material is recommended to withstand the stroke of the rammer.SIST EN 1402-5:2004
