17、age 4 prEN 4523: 1998 4 Health and safety Resources, test pieces, test samples, test materials, test equipment and test procedures shall comply with the current health and safety regulationsllaws of the countries where the test is to be carried out. Where materials and/or reagents which may be hazar
18、dous to health are specified, appropriate precautions in conformity with local regulations and/or laws shall be taken. 5 Principle The test method involves subjecting a test piece to an increasing axial compressive load. 6 Testing requirements 6.1 Resources 6.1.1 Equipmentlplant See ASTM E9-89a. Met
19、ric dimensions shall apply. For references to ASTM E4 (Load verification of testing machines) substitute EN 10002-2. For references to ASTM E83 (Verification and classification of extensometers) substitute EN 100024 6.1.2 Materials/Reagents Materialsheagents included may be suitable: - degreasing fl
20、uids; - recording paper; - means of electronic recording, if appropriate. 6.1.3 Qualification of personnel Testing to the requirements of this test method shall only be undertaken and/or supervised by personnel who have demonstrated their competence by a suitable education and appropiate training an
21、d experience. 6.2 Test samplesTest pieces See ASTM E949a. Metric dimensions shall apply. NOTE: In certain cases the test piece may be the test sample. 6.3 Testing procedure See ASTM E9-89a. Metric dimensions shalt apply. 6.3.1 Temperature of test The test shall be carried out at 10 “C I 0s 35 “C, un
22、less otherwise specified. In cases of dispute the test shall be performed at B= 23 “C f 5 “C. 6.4 Expression of results See ASTM E9-89a. Metric units shall be used.
