9、 BSI iv Foreword 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 member body interested in a subject for w
10、hich 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 Electrotechnical Commission (IEC) on all
11、 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 adopted by the technical committees are c
12、irculated 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 patent rights. ISO shall not be held resp

15、:34:02 GMT+00:00 2007, Uncontrolled Copy, (c) BSI v Introduction Throughout the world, a large number of plastics drum types with different dimensions and characteristics are being used. The differences in the minimum filling opening and outer dimensions result in differences in filling, handling an
16、d transportation. ISO 20848 specifies the characteristics and dimensions of plastics drums which are of importance for the worldwide safe handling and transport of substances and for the continued reuse of the drums during their life cycle. Detailed performance requirements and the related test meth
17、ods are not included as they depend upon the specific application. Where the drums are intended to be used for the transport of dangerous goods, attention is drawn to the regulatory requirements which govern the transport of those goods in the countries concerned, including capseals/overseals fitted
18、 in accordance with the certificate. Depending upon the mode of transport, this means meeting the requirements of: UN (United Nations) Recommendations on the Transport of Dangerous Goods, ICAO (International Civil Aviation Organization) Technical Instructions for the Safe Transport of Dangerous Good
19、s by Air, IMO (International Maritime Organization) International Maritime Dangerous Goods (IMDG) Code. This involves the certification and marking of the drums according to the regulations.

40、 capacity is determined by a gravimetric method, i.e. by the measurement of the mass of water in the filled drum and its conversion to a capacity. A correction factor can be applied according to Table A.1, but only if the weighing scale used is of a higher precision than the correction. Table A.1 Co
41、rrection factors Water temperature C Correction factor, F 12 1,000 5 14 1,000 8 16 1,001 1 18 1,001 4 20 1,001 8 22 1,002 2 24 1,002 7 27 1,003 6 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 For
42、 removable head (open head) drums, place the Iid, fitted with a closure for filling purposes, on the drum and close it using the recommended method. A.3.2 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
43、of the top. A.3.3 Weigh the empty drum and record its mass, m1, in grams. A.3.4 Measure the temperature of the tap water to be used to fill the drum. A.3.5 Fill the drum 100 % with water through the filling opening and make sure that air is vented through the drilled hole. NOTE For certain drums, th
44、e drum needs to be inclined or tilted, so that the filling hole is at the highest position. A.3.6 Fit and secure the drum closure and remove any surplus water from the outside. A.3.7 Weigh the filled drum and record its mass, m2, in grams. BS ISO 20848-1:2006 Licensed Copy: London South Bank Univers

Fil
46、l 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 necessary multiplied by the correction factor F, represents the capaci
47、ty of the drum as determined by the procedure used.
