BS EN 15507:2017EN 15507:2017 (E) 4 Introduction This European Standard was developed to provide requirements and test procedures for comparative testing of polyethylene grades of high and medium molecular we

26、ight high density polyethylene, used for the manufacture of packaging and IBCs for the transport of dangerous goods. These specific material parameters relate to the test procedures described in the standards: EN ISO 13274:2013, Packaging Transport packaging for dangerous goods Plastics compatibilit

27、y testing for packaging and IBCs (ISO 13274:2013 + Cor. 1:2014) EN ISO 16495:2013, Packaging Transport packaging for dangerous goods Test methods (ISO 16495:2013) The aim of the test methods described in this European Standard is to provide information for consideration as part of a selective test p

28、rocedure. Selective testing procedures, are described in Clause 8 in the standards above and can eliminate or reduce the requirement to carry out the full test procedures described each time a new grade of high density polyethylene is used for the manufacture of the same design type. The test requir

29、ements and procedures in the standards above for plastics packaging and IBCs meet the provisions set out in the multimodal 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 regul

30、ations for the international transport of dangerous goods, details of which can be found in the Bibliography. These 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 N

31、orthern Africa) 2; the International Civil Aviation Organizations Technical Instructions for the Safe Transport of 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 dang

32、erous Goods by Rail (RID), (covering most of Europe, parts of North Africa and the Middle East) 5. The application 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

33、 is important to note that there will be certain modal differences from the UN Recommendations and that the schedule 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

34、 of the UN Recommendations. This European Standard has been submitted for reference into the RID and/or the technical annexes of the ADR. BS EN 15507:2017EN 15507:2017 (E) 5 1 Scope This European Standard specifies material parameters, test requirements and procedures for the comparative testing of

35、polyethylene grades of high molecular weight high density polyethylene (PE-HD-HMW) and medium molecular weight high density polyethylene (PE-HD-MMW), used for the manufacture of packaging and IBCs for the transport of dangerous goods. It is intended to be used in conjunction with selective testing f

36、or packaging for liquids. The standard is not intended to be used for comparative testing of recycled plastics material. NOTE 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 followi

42、 C after annealing at 100 C for 30 min, and a melt mass-flow rate at 190 C/21,6 kg load of 940 kg/m3, when measured at 23 C after annealing at 100 C for 30 min, and a melt mass-flow rate at 190 C/2,16 kg load of 0,1 g/600 s in accordance with EN ISO 1133-1, or a melt mass-flow rate at 190 C/5 kg loa

43、d 0,5 g/600 s in accordance with EN ISO 1133-1 Note 1 to entry: Natural Polyethylene refers to material with no pigments or colorants. 4 Test requirements 4.1 General When a manufacturer of a plastics packaging or IBC wants to change to a new grade of high density polyethylene for its manufacture, t

44、est results to the following requirements may be used in conjunction with a selective testing procedure to reduce the amount of design type testing of the design type with the new polyethylene grade. As a minimum requirement, a test with water as the test medium in accordance with EN ISO 16495 shall

45、 be carried out for the packaging design type manufactured from the new polyethylene grade. The test requirements in 4.2 to 4.6 shall be met in the comparative testing of the polyethylene grade with existing approvals, (Material A), and the replacement polyethylene grade, (Material B). The comparati

46、ve testing of the polyethylene grades to the procedures defined in 7.1 to 7.5 shall be carried out concurrently in a single laboratory. For the procedures 7.2 to 7.5, test sheets (see 5.2) compression moulded by the same mould type (e.g. using a positive mould or semi-positive mould) shall be used.

47、4.2 Melt mass-flow rate (MFR) When tested in accordance with 7.1 the value of melt mass-flow rate shall be within the following limits: 70 % MFR Material A MFR Material B 130 % MFR Material A. NOTE The determination of melt mass-flow rate is solely intended as a classification test for the polyethyl

48、ene grade and does not relate to any of the tests for packaging described in EN ISO 13274 or EN ISO 16495. 4.3 Density When tested in accordance with 7.2 the density in kg/m3shall be: Density Material B (DB) Density Material A (DA) 2. NOTE The determination of density is intended to relate to the pe

49、rformance of packaging and IBCs produced from the polyethylene grades, such as those tested in accordance with EN ISO 16495:2013, following conditioning with standard liquids described in EN ISO 13274:2013, Clause 8: EN ISO 16495:2013, Annex F Drop test; EN ISO 16495:2013, Annex I Stacking test; EN ISO 16495:2013, Annex H Hydraulic pressure test and the Permeability test in EN ISO 13274:2013, 4.11.
