20、he world, a large number of plastics drum types with different dimensions and characteristics are being used. The differences in location of the minimum filling opening and outer dimensions result in differences in filling, handling and transportation. ISO 20848 specifies the characteristics and dim
21、ensions 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 methods are not included as they depend upon the specific application
22、. 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 in accordance with the certificate. Depending upon the mode of t
23、ransport, 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 Goods by Air, IMO (International Maritime Organization) International
24、 Maritime Dangerous Goods (IMDG) Code. This involves the certification and marking of the drums according to the regulations.

38、ures There shall be two closures in accordance with ISO 20848-3. When fitted, the closures shall not protrude above the overall height of the drum. The preferred options are identified in Table 2. The closure systems shall incorporate a facility for providing tamper evidence. For the purpose of tran
39、sport and storage, the filled drum should be closed, using the appropriate tooling, to the manufacturers recommended closure torque for each type of gasket. NOTE 1 For closures in drums intended for dangerous goods, the tolerance on the torque figures are specified in ISO 16104. NOTE 2 After tighten
40、ing of plugs, torques will reduce over time. In particular, plastics components are subject to stress relaxation resulting in a reduced torque. NOTE 3 Torque figures supplied by the manufacturer are valid for the tightening of plugs in a clockwise direction. The measurement of torques on releasing p
41、lugs, i.e. in an anticlockwise direction, are different.

42、erial, or a combination thereof. Suitable non-plastics material may be used in conjunction with the plastics material. NOTE Suitable additives may be included provided the specifications are identified. 4.6 Handling Provision shall be made to enable the drum to be mechanically handled using one or t
43、wo permanently fixed handling rings. The construction of the handling rings shall be adequate for normal static and dynamic handling of filled drums. 4.7 Stacking The drum shall be capable of being stacked with or without pallets, according to the manufacturers recommendations.

The residue shall be not more than 100 ml when tested according to B.3.
45、4.8.2 The residue obtained when the drum is tested according to B.4 is more dependent on the area and condition of the internal surface of the drum than when the drum is tested according to B.3 and, therefore, may be in excess of that obtained according to B.3. NOTE The maximum permitted figure shou
46、ld be agreed between the purchaser and the supplier. 4.9 Finish The external surface finish shall be suitable for the attachment of labels. NOTE 1 The nature of the internal and external finish should be agreed between the purchaser and the supplier. The drum body should be blue in colour. The use o

49、d, 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.
