31、d, the following terms and definitions apply. 3.1 LPG mixture of light hydrocarbons, gaseous under standard atmospheric conditions, which can be liquefied by increased pressure or decreased temperature. The main components are propane, propene, butane and butene isomers 3.2 contents gauge device to
32、indicate the liquid level or contents in a tank NOTEThis can be incorporated into an overfill protection device. 3.2.1 float gauge device to indicate the content of a tank by means of a float on the liquid surface within the tank 3.2.2 rotary gauge device which operates through a rotating action in
33、order to assess the liquid level in a tank by means of temporarily venting a limited amount of LPG, whereupon the change from liquid to vapour is detected 3.2.3 fixed level gauge device to indicate when a predetermined liquid level in a tank has been reached or surpassed 3.2.4 slip tube device which
34、 operates through a linear action in order to assess the liquid level in a tank by means of temporarily venting a limited amount of LPG, where upon the change from liquid to vapour is detected 3.3 overfill protection device device that automatically stops the filling of liquid into the tank when a p
35、redetermined level has been reached 3.4 external tightness resistance to leakage through the gauge body to or from the atmosphere 3.5 internal tightness resistance to leakage across the gauge seat or other internal sealing components when the gauge is closed Licensed Copy: London South Bank Universi

37、is expected to be exposed during normal use is minus 20 C. In service temperatures below this may be encountered during short periods, for example, when filling; in some parts of Europe and for certain applications, lower minimum operating temperatures are necessary. Where the device is subject to m
38、ore severe temperature conditions, the design temperature range shall be extended to minus 40 C. When gauges are designed for a temperature lower than minus 20 C, they shall meet the requirements of annex B; the maximum operating temperature to which the gauge is expected to be exposed during normal
39、 operation is 60 C. In service, this temperature may be exceeded for short periods; the maximum allowable pressure is 25 bar; the minimum pressure to which a gauge is normally exposed is zero bar gauge. Vacuum conditions on the gauge, arising from butane at low temperature or evacuation of the tank
40、can expose the device to a vacuum of 50 mbar absolute. 5 Materials 5.1 General 5.1.1All materials in contact with LPG shall be physically and chemically compatible with LPG under all the normal operating conditions for which the contents gauge is intended. 5.1.2Materials for gauge components shall b
41、e selected to give adequate strength in service. Consideration shall also be given to other modes of failure such as atmospheric corrosion, brass dezincification, stress corrosion, impact or material failure. 5.1.3Alternative materials to those listed in 5.2 are not precluded, providing they comply
42、with a standard or specification that ensures control of chemical and physical properties, and quality appropriate to the end use. 5.2 Metallic materials 5.2.1Metallic materials for gauges shall be steel, stainless steel, copper alloys, aluminium alloys, zinc alloys, or other suitable materials. 5.2
43、.2For pressure containing components: steel and stainless steels shall comply with EN 1503-1 or EN 1503-2; cast iron shall comply with EN 1503-3; and copper alloys shall comply with prEN 1503-4. 5.2.3Stainless steel for components shall contain not less than 17 % chromium, and not less than 7 % nick
44、el. Springs shall be manufactured from stainless steel in accordance with EN 10270-3 or a material with an equivalent resistance to corrosion. 5.2.4Components made from hot stamped brass shall be non-porous and suitable for machining or other processing.

Leaded brass shall be CW614N or CW617N in accordance with EN 12420 and EN 12164. Cold drawn brass rods up to 45 mm wide in cross section may be used afte
46、r heat treatment and adequate testing for internal cracking. Cold drawn brass rods greater than 45 mm wide in cross-section shall not be used. Components produced from stamping brass shall not exhibit cold shuts also known as folds, or surface defects. Components manufactured from hot stamped brass
47、or contents gauge bodies made of drawn brass or machined from brass rod shall be capable of withstanding, without cracking, the stress-cracking test. 5.2.5Spheroidal graphite cast iron in accordance with EN 1563, with an elongation at fracture of more than 18 %, may be used. Other ductile irons or c
48、ast irons shall not be used. 5.2.6ZnAl4 and ZnAl4Cu1 shall be in accordance with ISO 301. 5.2.7Castings shall be free from inclusions and surface defects which could adversely affect the strength, leak tightness or performance of the contents gauge. 5.3 Non-metallic components All non-metallic mater
49、ials in contact with LPG shall be compatible with LPG and shall not distort, harden or adhere to the body or seat face to such an extent that they impair the function of the gauge and shall also comply with the appropriate requirements of EN 549. All elastomeric materials in contact with LPG shall meet the specific requirements of EN 549 for resistance to the following: gas (pentane test); lubricants; ageing; low temperatu
