11、dard shall be used in conjunction with the relevant sections of the latest issue of BSL100. 2 Quality of material The material shall be made from aluminium of the chemical composition specified in clause3, with or without approved scrap at the discretion of the manufacturer. NOTEIn the manufacture o
12、f this tube, the use of bridge or port dies is prohibited. 3 Chemical composition The chemical composition of the material shall be: 4 Condition The tube shall be supplied cold drawn. 5 Heat treatment None. 6 Mechanical properties 6.1 Tensile test. The tensile strength of test pieces selected and pr
13、epared in accordance with the relevant requirements of BSL100 shall be not less than the following values: 6.2 Single drifting test. The specified percentage of the tubes shall be subjected to the single drifting test. NOTEThe test pieces may be annealed before being tested. 6.3 Hydraulic distention
14、 test. One sample of the tube at least500mm long in each batch shall be tested to the appropriate pressure determined from the following formula, subject to a maximum of27.6MPa and a minimum of2.1MPa: The sample tube shall not burst, nor show a permanent increase in mean diameter greater than0.2%.
