EN 14617-9:2005 (E) 4 1 Scope This document specifies a method for determining the impact resistance of agglomerated flat stone products. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated refe
23、rences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Not applicable. 3 Principle The impact resistance is determined by the dropping of a spherical steel ball from given increasing heights until the specimen
24、 breaks. 4 Apparatus 4.1 A steel sphere with mass of 1,0 kg 0,1 kg and diameter of about 6,3 cm. 4.2 An electromagnet with a ball bearing housing and a switch. 4.3 A vertical stick graduated at 5 cm intervals from 0 cm to 120 cm, along which the electromagnet can travel. 4.4 A box of minimum section
25、 40 cm X 40 cm and no less than 30 cm high, containing a bed of dry sand at least 20 cm deep. The sand grain size distribution should be in the 1 mm 1,5 mm range. 5 Preparation of the specimens At least four specimens should be prepared with 20 cm X 20 cm sides. The sample thickness should be betwee
26、n 0,5 cm and 3 cm and should equal the one of the final product. The main faces must be parallel and with the finishing of the end product (sand blasted, gauged or polished surface) faced to the falling sphere but without any chemical surface treatment. 6 Test procedure Lay the sample in the centre
27、of the box on the bed of sand so that the whole thickness is buried. It should be placed so that the centre of the face with the larger size lies on the vertical passing through the vertical of the sphere. A spirit level should be used to check that the upper face of the sample lies horizontal. The
28、electromagnet should be attached to the stick at a point corresponding to the 6 cm drop (from the bottom) of the sphere. Switch off the electromagnet and let the sphere fall. The drop height (h) should be measured between the lowest point of the sphere and the impact surface. Repeat the test by prog
29、ressively increasing the drop height 5 cm at a time until the sample is broken. Any surface damage caused by the steel sphere drop will be visually noticed in comparison with reference specimens, recorded and reported in the test results. ? EN 14617-9:2005 (E) 5 7 Expression of results The fracture
30、work L in joule is expressed by the formula L= M h g where M is the sphere mass in kg; h is the drop height in meters of the sphere which causes the sample to break; g is the gravity acceleration equal to 9,806 m /s 2 The final data must be obtained by averaging the results from at least four specim
31、ens. 8 Test report The test report shall contain the following information: a) unique identification number of the report; b) number, title and date of issue of this document; c) name and address of the test laboratory and the address where the test was carried out if different from the test laborat

The test report shall contain the signature(s) and role(s) of the responsible(s) for the testing and the written consent of the test laboratory. It shall also stated that the report shall not be partially reproduced without the
