Endorsement notice The text of ISO 20848-2:2006 has been approved by CEN as a EN ISO 20848-2:2008 without any modification. Introduction Thro
23、ughout the 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
24、 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 methods are not included as they depend upon the specific app
25、lication. 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 m
26、ode 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 Goods by Air, IMO (International Maritime Organization) Inter
27、national Maritime Dangerous Goods (IMDG) Code. This involves the certification and marking of the drums according to the regulations. 4 DIN EN ISO 20848-2:2008-09 EN ISO 20848-2:2008 (E) 1 Scope This part of ISO 20848 specifies the characteristics and dimensions of non-removable head (tight head) pl

38、2 Drum mass The mass tolerance of the drum shall be 3 %. NOTE The defined mass should be agreed between the purchaser and the supplier. 4.3 Material identification symbol The drum shall be permanently marked with the relevant material identification symbol, i.e. the symbol identifying the material f
39、rom which the drum is made, as shown in Annex C. 7 EN ISO 20848-2:2008 (E) DIN EN ISO 20848-2:2008-09 4.4 Closures 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 Ta
40、ble 2. The closure systems shall incorporate a facility for providing tamper evidence. For the purpose of transport 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 inte
41、nded for dangerous goods, the tolerance on the torque figures are specified in ISO 16104. NOTE 2 After tightening 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 manufact
42、urer are valid for the tightening of plugs in a clockwise direction. The measurement of torques on releasing plugs, i.e. in an anticlockwise direction, are different.

43、5 4.5 Materials The drum shall be manufactured from high-density polyethylene or another suitable plastics material, 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
44、 identified. 4.6 Handling Provision shall be made to enable the drum to be mechanically handled using one or two 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 o

The residue shall be not more t
46、han 100 ml when tested according to B.3. 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.
47、3. NOTE The maximum permitted figure should 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
48、 body should be blue in colour. The use of any other colour and any durable marking should be agreed between the purchaser and the supplier. 5 Designation A non-removable head (tight head) drum (TH) manufactured in accordance with this part of ISO 20848 with a nominal capacity of 220 l shall be so d
