23、2 O3002(E) I SO 3002 All irhgts seredevr iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each membe

24、r body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elec

25、trotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopt

26、ed by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of paten

27、t rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20823 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.

28、and related products Determination of the flammability characteristics of fluids in contact with hot surfaces Manifold ignition test WARNING The use of this International Standard may involve hazardous materials, operations and equipment. This International Standard does not purport to address all o

29、f the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This International Standard specifies a test method

30、to determine the relative flammability of fluids when contacted with a hot metal surface at a fixed temperature, but it is also possible to gauge fluid ignition temperatures by adjustment of the manifold temperature. It is primarily used to assess the resistance to ignition of fire-resistant hydraul

31、ic fluids which are, by definition, difficult to ignite. It may be used with other types of more flammable fluids at lower surface temperatures, but this could significantly increase the hazards of this procedure. NOTE The procedure given in this International Standard is specified in ISO 12922:1999

NOTE 2,2,4-trimethylpentane, heptane or petroleum spirit boiling between 60 C and 80 C are suitable. 5 Apparatus 5.1 Simulated manifold test rig 5.1.1 General The rig consists of a

36、 heated simulated manifold supported in a box frame, and is illustrated in Figure 1. It shall be located in a fire-resistant enclosure with adequate ventilation to remove toxic and/or noxious combustion or decomposition products. 5.1.2 Manifold support A sheet metal box of dimensions 300 mm 300 mm 4

37、50 mm, open at the top and front. Holes of 78 mm nominal diameter shall be cut in the sides in such a position that the manifold is positioned and supported so that its major axis is held at an angle of 7 to the horizontal, and the centre-point of the manifold is 270 mm 10 mm above the surface of th

38、e drip tray or bottom of the support. The bottom of the box shall either contain a separate drip tray, or be so shaped as to contain all drips of liquid falling from the manifold. The diameter of the holes in the box should be just sufficient to accommodate the simulated manifold (5.1.3) complete wi

40、ll irhgts seredevr 35.1.3 Simulated manifold The manifold, illustrated in Figure 2, is constructed from corrosion-resistant steel tubing of 75 mm nominal outside diameter and 1 mm wall thickness. It shall be 500 mm 50 mm in length. The exterior of the tube shall be sandblasted. A corrosion-resistant

41、 steel rod, 3 mm in diameter and 250 mm in length, is tack welded to the exterior surface of the tube such that the major axes are parallel, and the mid-point of the long axis of the rod corresponds to that of the tube. 5.1.4 Manifold heater A heating element shall be mounted centrally within the ma

42、nifold tube by means of suitable washers constructed from thermal insulation material. The element shall be capable of heating and maintaining a temperature of 700 C 5 C on the exterior surface of the manifold tube over the central portion of approximately 305 mm of the tube, whilst the enclosure ve

43、ntilation (5.1.1) is switched on. The terminals to the tube heater shall be enclosed. NOTE A rod pattern, silicon carbide type or equivalent, of 25 mm diameter and overall length 790 mm, and nominal electrical resistance 0,62 , has been found suitable. 5.1.5 Temperature sensors Temperature sensors s

44、hall be mounted in contact with the manifold tube surface in order to monitor the temperature close to the expected point of impact of the fluid. Each sensor shall be connected to a temperature indicator. Take care to minimize any additional radiating surfaces in the attachment of the sensor(s). NOT

45、E A mobile spring-loaded plate temperature sensor is preferred. If not available, three sensors located approximately 145 mm apart over the central portion of the manifold tube surface, placed to avoid fluid running off across the sensors, will be satisfactory. 5.2 Fluid dispenser A device, mounted

46、vertically above the centre-line of the manifold, that can measure 10 ml 0,5 ml of fluid, and dispense it at a controlled and constant rate over 50 s 10 s. The dispenser shall be mounted on a stand that allows measured movements horizontally along the axis of the tube and parallel to it. The height

47、of the dispenser outlet above the surface shall be measured and recorded. NOTE Manual use of a burette or similar device is not recommended in view of the safety hazard associated with the fluid igniting on the manifold.
