The differences in the minimum filling opening and outer dimensions res
20、ult in differences in filling, handling and 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 performa
21、nce requirements and the related test methods 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 conc
22、erned, including capseals/overseals fitted 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 Instruction
23、s for the Safe Transport of Dangerous Goods 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. BS EN ISO 20848-1:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA S

43、pacity measurement method for removable head (open head) plastics drums A.1 Principle The 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 o
44、nly if the weighing scale used is of a higher precision than the correction. 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 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 %
45、of the weight being measured. A.3 Procedure for determination of total capacity A.3.1 For 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 th
46、e highest point of the closed drum. NOTE The position of the hole depends on the profile 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 open
47、ing and make sure that 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.3.6 Fit and secure the drum closure and remove any surplus water from the outside. A.3.7 Weigh the filled drum and re
48、cord its mass, m2, in grams. BS EN ISO 20848-1:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 26/02/2009 07:19, Uncontrolled Copy, (c) BSI6 A.4 Procedure for determination of brimful capacity Follow the same procedure as for the determination of total capacity (see A.3) with the exceptio
49、n 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 necessary multiplied by the correction factor F, represents the capacity of the drum as determined by the procedure used.
