16、15507:2008EN 15507:2008 (E) 4 Introduction This European Standard was developed to provide requirements and test procedures for comparative testing of grades of high and medium molecular weight high density polyethylene, used for the manufacture of packagings and IBCs for the transport of dangerous

17、goods. These specific material parameters relate to the test procedures described in the standards: EN ISO 16101, Packaging Transport packaging for dangerous goods Plastics compatibility testing (ISO 16101:2004) EN ISO 16104, Packaging Transport packaging for dangerous goods Test methods (ISO 16104:

18、2003) EN ISO 16467, Packaging Transport packaging for dangerous goods Test methods for IBCs (ISO 16467:2003) The use of the test methods described in this European Standard is to facilitate usage in selective testing procedures, as described in Clause 8 eliminating or reducing the requirement to car

19、ry out the full test procedures described in the standards above each time a new grade of high density polyethylene is used for the manufacture of the same design type. The test requirements and procedures in the standards above for plastics packagings and IBCs meet the provisions set out in the mul

20、timodal United Nations Recommendations on the transport of Dangerous Goods 1. These UN Recommendations are given legal entity by the provisions of a series of modal agreements and regulations for the international transport of dangerous goods, details of which can be found in the Bibliography. These

21、 international agreements include: the European Agreement concerning the International Carriage of Dangerous goods by Road (ADR), (covering most of Europe as well as parts of Asia and Northern Africa) 2; the International Civil Aviation Organisations Technical Instructions for the Safe Transport of

22、Dangerous Goods by Air (ICAO TIs), (world-wide) 3; the International Maritime Dangerous Goods Code (IMDG Code), (world-wide) 4; regulations concerning the International Carriage of dangerous Goods by Rail (RID), (covering most of Europe, parts of North Africa and the Middle East) 5. The application

23、of this standard will need to take account of the requirements of these international agreements and the relevant national regulations 6, 7 for domestic transport of dangerous goods. It is important to note that there will be certain modal differences from the UN Recommendations and that the schedul

24、e for revision of the UN Recommendations and modal provisions may lead to temporary inconsistencies with this European Standard, which is regularly updated to reflect the latest version of the UN Recommendations. This European Standard has been submitted for reference into the RID and/or the technic

25、al annexes of the ADR. BS EN 15507:2008EN 15507:2008 (E) 5 1 Scope This European Standard specifies material parameters, test requirements and procedures for the comparative testing of grades of high molecular weight high density polyethylene (PE-HD-HMW) and medium molecular weight high density poly

26、ethylene (PE-HD-MMW), used for the manufacture of packagings and IBCs for the transport of dangerous goods. It is intended to be used in conjunction with selective testing for packagings for liquids. The standard is not intended to be used for comparative testing of recycled plastics material. NOTE

27、This European Standard is intended to be used in conjunction with one or more of the international regulations set out in the Bibliography. 2 Normative references The following referenced documents are indispensable for the application of this document.
