23、inders Basic requirements and definitions. 3 Definitions For the purpose of this European Standard the following definitions apply. 3.1 acetylene cylinder cylinder containing a porous mass with or without solvent for the storage of acetylene EN 1800:1998 3.2 tare weight 3.2.1 for acetylene cylinders
24、 with solvent the tare weight is expressed by indicating two weights (in kilograms) TARE 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 that a
25、re permanently attached (e.g. by clamping or nut bolt fixing) to the cylinder when it is going to be filled; TARE S is TARE A plus the weight of the acetylene required to saturate the solvent at atmospheric pressure at 15 8C. EN 1800:1998 3.2.2 for solvent free acetylene cylinders the tare weight is
26、 expressed by indicating a TARE F, where TARE F is TARE A minus the weight of solvent EN 1800:1998 3.2.3 if the tare weight 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 i
27、n front of the letters TARE (e.g. 2.3 TARE 75.1/75.6 KG) EN 1800:1998 3.3 total weight for cylinders with solvent, total weight is TARE A plus the weight of the maximum acetylene content; for solvent free cylinders, total weight is TARE F plus the weight of the maximum acetylene content. EN 1800:199
28、8 3.4 maximum acetylene content the specified maximum weight of acetylene in the cylinder (in kilograms); when a solvent is used, it includes the weight of saturation gas EN 1800:1998 3.5 porous mass single or multi-component material introduced or formed in the cylinder in order to fill it and whic
29、h, due to its porosity, allows the absorption of the solvent/acetylene gas solution NOTE 1The porous mass may be either: monolithic, consisting of a solid product obtained by reacting materials or by materials connected together with a binder, or: non-monolithic, consisting of granular, fibrous or s
30、imilar materials without addition of a binder. EN 1800:1998 3.6 approved porous mass mass which has a type approval (see EN 1800:1998) 3.7 residual gas the weight of acetylene in a cylinder returned for filling; it is defined: for a cylinder with TARE A or TARE F as the entire weight of acetylene; f
31、or a cylinder with TARE S as the entire weight of acetylene minus the weight of the saturation acetylene. 3.8 solvent liquid which is absorbed by the porous mass and is capable of dissolving and releasing the acetylene prEN 1800:1998 3.9 acetylene solvent ratio the ratio of the maximum acetylene con

33、rements for filling single acetylene cylinders 4.1 General Single acetylene cylinders shall not be filled unless they meet the requirements of 4.2 to 4.4. 4.2 Information The following information shall be available: the identification of porous mass; the specified type and content (in kilograms) of
34、 solvent; the tare weight; the total weight; the periodic inspection status. 4.3 Documentation For cylinders examined in 4.2 documentation shall be available to determine: the filling conditions for the cylinder; the residual gas and hence to obtain the solvent content. Documentation may be in form
35、of tables, graphics or other suitable means. 4.4 Prefill check The prefill check of an acetylene cylinder and its valve shall ensure that they are both in a serviceable condition for filling. 5 Determination of solvent content 5.1 Before filling a cylinder the solvent content shall be determined by
36、calculating the residual gas from pressure and temperature and using the appropriate documentation. NOTEAcetylene cylinders need time to reach temperature equilibrium. Special care should be taken, if the temperature is very low and the pressure is very high. Calculation of acetylene in cylinders sh
37、all be in accordance with annex B. (Solvent free cylinder see clause 8.) 5.2 If the weight of the incoming acetylene cylinder, after deduction of the residual gas, is below the appropriate tare weight, which is stamped on the cylinder, the loss of solvent shall be replaced. 5.3 If the weight of the
38、incoming cylinder after allowing for residual gas content exceeds the appropriate tare weight, the cylinder shall be examined and the reason for overweight shall be determined before further handling. 6 Simultaneous filling of acetylene cylinders Acetylene cylinders which are to be filled simultaneo
39、usly shall have the same solvent or be separated by a protection system to prevent cross contamination with solvents. Special care shall be taken with cylinders having different porous masses or high amounts of residual gas. 7 Postfill check After the cylinder has been filled its weight shall be che
40、cked to ensure that it does not exceed the total weight (see 3.3). NOTEAs the solvent content has been verified as correct in clause 5, there is no need for control of the working pressure of each individual cylinder because of the acetylene to solvent ratio established during the type approval. 8 F
41、illing of solvent free acetylene cylinders 8.1 A solvent free cylinder shall not be filled with acetylene, unless it meets the following requirements: it is clearly identified with the words solvent free, stamped with the value of TARE F in kg and the letters FS; it is checked by weight that it was
42、not previously filled with solvent; the appropriate requirements of clause 4 are fulfilled; the working pressure is identified; if it contains no residual acetylene, the cylinder shall be evacuated before filling. Solvent free acetylene cylinders shall not be filled simultaneously with acetylene cyl
43、inders containing a solvent. 8.2 After filling a solvent free acetylene cylinder, a postfill check shall be carried out in accordance with clause 7. The settled pressure shall be checked after filling and shall not exceed the working pressure, which is stamped on the cylinder. Page 5 EN 1801:1998 An
44、nex A (normative) Filling of acetylene cylinders not manufactured and approved in accordance with European Standards Acetylene cylinders which are not manufactured/approved in accordance with European Standards may be filled when the following checks are positive. a) The porous mass with the corresp
45、onding solvent shall be of an approved type and clearly identified. b) It shall be approved for the country of the filling station or in the country of usage or manufacture. c) The requirements of clauses 4, 5, 6 and 7 shall be followed. d) A calculation of the residual gas is possible and shall be
46、carried out. NOTEAlternatively the information for filling such cylinders should be obtained from the mass manufacturer or the organization responsible for the approval of the cylinder and mass. Annex B (normative) Calculation of acetylene in cylinders The calculation of acetylene in cylinders conta
47、ining either acetone or dimethylformamide (DMF) solvent is dependent upon the measurement of the pressure and temperature within the cylinder. Measurement of the cylinder weight alone will only give the total weight of solvent and acetylene in the cylinder but will not indicate the shortfall of solv
48、ent or the acetylene content including saturation gas. The acetylene-solvent ratio can be determined using the following equation: = Ma Ms 10f(p,t) 1 2 10f(p,t) where: Mais the weight of acetylene in kilograms (kg); Msis the weight of solvent in kilograms (kg); f(p,t)is a factor dependent upon press
49、ure, temperature and solvent. Since the solubility of acetylene in acetone and DMF is different there are two equations for the calculation of f(p,t): For acetone the equation is: f(p,t) = log10p 2 4,194 5 + 712,88 t + 273,15 0,456 9 + 207,8 t + 273,15 For DMF the equation is: f(p,t) = log10p 2 3,630 + 504,36 t + 273,15 20,982 6 + 695,8 t + 273,15 where: pis the pressure in bar absolute; tis the temperature in 8C. NOTEThe specified weight of solvent content should be used in the equation for calcul
