33、ated: Plastics drum TH EN 12707 NC 210 l to 225 l. EXAMPLE 2 A non-removable head (tight head) drum with a nominal capacity of 225 l would be designated: Plastics drum TH EN 12707 NC - 225 l NOTE Where the drums are intended to be used for the transport of dangerous goods, attention is drawn to the

34、regulatory requirements which govern the transport of those goods in the countries concerned. In Europe, depending upon the mode of transport, this means meeting the requirements of: European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR); Regulations concerning the

35、 International Carriage of Dangerous Goods by Rail (RID); Technical Instructions for the Safe Transport of Dangerous Goods by Air, Document 9284-AN/905 published by the Council of the International Civil Aviation Organization (ICAO); The International Maritime Dangerous Goods Code (IMDG-CODE) publis

39、 by the measurement of the mass of water in the filled drum and its conversion to a capacity. A correction factor (see EN ISO 90-2:1999, 4.1.1.) can be applied according to Table A.1, but only if the weighing scale used is of a higher precision than the correction. NOTE For plastics drums the water

40、temperature should not exceed 18C. Table A.1 Correction factors Water temperature C Correction factor (F) 12 1,000 5 14 1,000 8 16 1,001 1 18 1,001 4 A.2 Apparatus Weighing scale, with an accuracy of at least 0,1% of the weight being measured. A.3 Procedure for determination of total capacity A.3.1

41、Drill a hole of diameter 5 mm to 10 mm for venting at the highest point of the closed drum. NOTE The position of the hole depends on the profile of the top. A.3.2 Weigh the empty drum and record its mass, m1,in grams. A.3.3 Measure the temperature of the tap water to be used to fill the drum. A.3.4

42、Fill the drum 100 % with water through the normal filling closure with all other closures fitted and make sure that the air is vented through the drilled hole. NOTE For certain drums, the drum needs to be inclined or tilted, so that the filling hole is at the highest position. A.3.5 Fit and secure t

43、he drum closure and remove any surplus water from the outside. A.3.6 Weigh the filled drum and record its mass, m2, in grams. BS EN 12707:2009EN 12707:2009 (E) 9 A.4 Procedure for determination of brimful capacity Follow the same procedure as for the determination of total capacity (see A.3) with th

44、e exception that no hole is drilled to vent entrapped air. Fill the drum, with the drum in the normal position for filling, until water overflows at the closure. A.5 Expression of results The difference between the mass of the filled drum, m2, and the mass of the empty drum, m1, (m2 m1), if necessar

45、y multiplied by the correction factor (F), represents the capacity of the drum as determined by the procedure used. BS EN 12707:2009EN 12707:2009 (E) 10 Annex B (normative) Draining test method for non-removable head (tight head) plastics drums B.1 Principle The absolute drainability and the relativ

46、e drainability are obtained by determining the mass of water left as a residue in the drum after drainage under gravity. B.2 Apparatus Weighing scale, with an accuracy of at least 2 g. B.3 Determination of drainability using the top section of the drum (procedure A) B.3.1 Cut the top off the drum. B

47、.3.2 Retain the top section and fit the appropriate closure(s). B.3.3 Weigh the top section with closure(s) fitted, and record its mass, m1,in grams. B.3.4 Position the top section, top down, on a test rig so that it is held at the angle specified by the manufacturer (preferably 0 to 20) with the de

48、signated closure opening at its lowest position. B.3.5 Fill the top section with approximately 10 l of tap water. B.3.6 Wait until the water surface has settled and then open the closure. B.3.7 Allow the water to drain for 5 min without moving or shaking the top section and refit the closure. B.3.8

49、Re-weigh the top section, still in the top down position, and record its mass, m2, in grams. B.4 Determination of drainability using a complete drum (procedure B) B.4.1 Weigh the empty drum including its closure(s), and record its mass, m1, in grams. B.4.2 Fill the drum with a limited quantity of tap water, approximately 10 l. Close the drum. B.4.3 Rotate the drum to ensure a wetting of all inner surfaces. B.4.4 Open th
