NOTE 1 Other standards for the design and construction of cylinders are in preparation and appropriate standards should be complied with when published. NOTE 2 This requirement does not exclude continued use and remassing of cylinder shells complying with national requirements. 4.1.2 The minimum test pressure for the cylinder shell shall be 60 bar (gauge). 4.2 Porous mass 4.2.1 The porous mass in the cylinder shall be of such quality that it enables the completed cylinder to pass the safety tests included in annex A. For safety reasons the porous mass shall be able to prevent or inhibit a dangerous decomposition of the acetylene. 4.2.2 There shall be no hazardous reaction between the shell, the porous mass, the acetylene, the solvent and any parts in contact with them, at any time. 4.2.3 To ensure the quality of the porous mass and the solvent, production/batch test procedures for the preparation of porous mass shall be established by the manufacturer in accordance with annex D. 4.3 Solvent The specified weight of solvent content shall be such that the cylinder can meet the requirements of the tests included in annex A. 4.4 Settled pressure When the cylinder has been charged to the maximum acetylene content and the pressure has reached equilibrium at a uniform temperature of 15 8C, the pressure in the cylinder shall not exceed the working pressure for the type of cylinder (calculated in accordance with annex C). 4.5 Cylinder identification The identification shall comply with the requirements of EN 1089-1:1996, EN 1089-2 and EN 1089-3. 4.6 Accessories Valves for use with acetylene cylinders shall conform to the requirements of EN 849:1996.
