Introduction Throughout the world, a large number of plastics drum types with different dimensions and characteristics are being used. The differences in types of closures may result in dif
24、ferences in filling and handling. ISO 20848 specifies the characteristics and dimensions of closures for 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 requireme
25、nts 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 concerned, includ
26、ing 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 Instructions for the Saf
27、e 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. 4 DIN EN ISO 20848-3:2008-09 EN ISO 20848-3:2008 (E) 1 Scope This part of ISO 20
28、848 specifies the characteristics and dimensions of plug/bung closure systems for internally threaded openings in plastics drums of nominal capacity 113,6 l to 220 l. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated reference
29、s, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

36、 specified. In addition, the appropriate tooling for closing shall be specified. 4.4 Material identification symbol All the plastics components of the closure systems, excluding gaskets, shall be permanently marked with the relevant material identification symbol, i.e. the symbol identifying the mat
37、erial from which the component is made as shown in Annex H. 6 DIN EN ISO 20848-3:2008-09 EN ISO 20848-3:2008 (E) 4.5 Materials The plug/bung and gasket, where used, shall be manufactured from materials appropriate to the physical and chemical requirements of their intended use. 4.6 Thread The thread
38、 shall be as specified in Figures A.1 to G.2. 4.7 Plug/bung The plug/bung shall be designed so that it can be inserted or removed by means of a simple tool. 4.8 Vented plug/bung For ease of identification when fitted in drums, a vented plug/bung and capseal/overseal shall be coloured yellow. A vente
39、d plug/bung used for drums intended to contain dangerous goods should be in accordance with the applicable regulations. A plastic plug should be fitted with a capseal/overseal of such a design as to ensure venting is not impeded. 4.9 Finish The nature of the internal and external finish of the plug/
40、bung and gasket shall be appropriate to the physical and chemical requirements of their intended use. NOTE The nature of the internal and external finish should be agreed between the purchaser and the supplier. 7 EN ISO 20848-3:2008 (E) DIN EN ISO 20848-3:2008-09 Annex A (normative) Plug/bung closur
