Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 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 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 16104:2003) 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 carry 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 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 regulations 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 Northern Africa) [2];  the International Civil Aviation Organisation’s 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 dangerous 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 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 of the UN Recommendations. This European Standard has been submitted for reference into the RID and/or the technical annexes of the ADR. SIST EN 15507:2009



EN 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 polyethylene (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
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.

EN 15507:2008 (E) 6 3.2 medium molecular weight high density polyethylene (PE-HD-MMW) natural polyethylene with a density of > 940 kg/m3, when measured at 23 °C after annealing at 100 °C for
30 min, and a melt flow rate at 190 °C per 2,16 kg load of < 0,5 g per 600 s and > 0,1 g per 600 s in accordance with EN ISO 1133:2005, Condition D, or a melt flow rate at 190 °C per 5 kg load < 3,0 g per 600 s and > 0,5 g per 600 s in accordance with EN ISO 1133:2005, Condition T NOTE 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, test 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 grade. As a minimum requirement, a test with water as the test medium in accordance with EN ISO 16104 or
EN ISO 16467 shall be carried out for the packaging design type manufactured from the new grade. The following test requirements in 4.2 to 4.6 shall be met in the comparative testing of the grade with existing approvals, (Material A), and the replacement grade, (Material B). The comparative testing of the 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. 4.2 Melt flow rate When tested in accordance with 7.1 the value of melt flow rate shall be within the following limits:  MFR Material B
≥
70 % MFR Material A;  MFR Material B ≤ 130 % MFR Material A. NOTE The determination of melt flow rate is solely intended as a classification test for t
