10、 18263-2:2015ISO 18263-2:2015(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intere
11、sted in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
12、Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documen
13、ts should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible
14、for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the

28、itions given in ISO 472 and ISO 15270 apply.4 Preparation of test specimensThe test specimens shall be prepared in accordance with ISO 1873-2 and shall be tested in accordance with each test method indicated in Table 1. It is essential that specimens are always prepared by the same procedure using t
29、he same processing conditions.5 Conditioning of test specimensTest specimens for the determination of mechanical properties and density shall be conditioned in accordance with ISO 291 for 40 h to 96 h at 23 C 2 C.6 Determination of ratio of PP and PEThe ratio of PP and PE shall be determined in acco
30、rdance with traceable documents from the supplier.NOTE In regard to the procedures etc. needed for the traceable documents on the recycled plastics, it is recommended to use EN 15343 or ISO/IEC 17050-1 and ISO/IEC 17050-2 as references. It is known that the ratio of PP and PE can be determined by FT
31、IR spectrometer, but sufficient precision data, especially including other materials, is not yet available (see Annex A).7 Determination of propertiesIn the determination of properties and the presentation of data, the standards, supplementary instructions, and notes given in ISO 10350-1 shall be ap
32、plied. All tests shall be carried out in the standard atmosphere of 23 C 2 C, unless specifically stated otherwise in Table 1 and Table 2.Table 1 is compiled from ISO 10350-1 and the properties listed are those which are appropriate for the mixtures of PP and PE recyclate for moulding and extrusion
33、materials. These properties are those considered useful for comparisons of data generated for different thermoplastics.Table 2 contains those properties which are in wide use or of particular significance in the practical characterization of mixtures PP and PE recyclate for moulding and extrusion ma
34、terials.NOTE This recyclate is derived from PP and PE used for flexible and rigid consumer packaging for moulding and extrusion. Therefore, there is no information about a stabilizer of recyclate and it may be necessary to add a stabilizer as needed.2 ISO 2015 All rights reservedBS ISO 18263-2:2015I
