30、inder cylinder containing a porous mass with or without solvent for the storage of acetylene NOTEFor solvent free acetylene cylinders see clause 6. 3.2 tare weight See EN 1089-1:1996. 3.2.1 for acetylene cylinders with solvent the tare weight is expressed by indicating two weights (in kilograms) TAR
31、E A and TARE S: TARE A is the sum of the empty weight of the cylinder shell, the weight of the porous mass, the specified weight of solvent content, the weight of the valve and the weight of all other parts which are permanently attached (e.g. by clamping or nut bolt fixing) to the cylinder when it
32、is going to be filled; TARE S is TARE A plus the weight of acetylene required to saturate the solvent at atmospheric pressure at 15 8C. 3.2.2 for solvent free acetylene cylinders the tare weight is expressed by indicating TARE F, where TARE F is TARE A minus the weight of solvent 3.2.3 if the tare w
33、eight, as defined in 3.2.1 or 3.2.2, includes permanently attached parts other than the valve (normally the fixed guard), the total weight of these parts is indicated by stampmarking in front of the letters TARE (e.g. 2,3 TARE 75,1/75,6 KG) 3.3 total weight for cylinders with solvent, total weight i
34、s TARE A plus the weight of the maximum acetylene content; for solvent free cylinders, total weight is TARE F plus the weight of maximum acetylene content 3.4 water capacity the capacity of the empty shell (excluding porous mass) when filled with water 3.5 maximum acetylene content the specified max
35、imum weight of acetylene in the cylinder (in kilograms); when a solvent is used it includes the weight of saturation gas Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 09:49:50 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 4 EN 1800:1998 BSI 02-2000 3.6 porous mass single or multi-componen

40、ments 4.1 Cylinder shell 4.1.1 The acetylene cylinder shell shall conform to the requirements of the appropriate European Standard for design and construction of the cylinders, i.e: for seamless steel, prEN 1964-1:1995; for seamless aluminium alloy, prEN 1975:1995. NOTE 1 Other standards for the des
41、ign 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
42、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 acetyle
43、ne. 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
44、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
45、 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 1089-1:199
