21、O 177:2017 (E)3 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 interested in a subjec
22、t 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 Commission (IEC)
23、 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 documents should be not
24、ed. 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 for identifying
25、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 convenience of

28、owing change: the normative references have been updated.DIN EN ISO 177:2017-05 EN ISO 177:2017 (E)4 1 ScopeThis document specifies a method for the determination of the tendency of plasticizers to migrate from plastics in which they are contained into other materials or other plastics when they are
29、 brought into close contact.NOTE 1 The surfaces into which the migration can proceed can also consist of organic surface coatings, such as lacquers.This test is suitablea) for evaluating the tendency displayed by plastics, particularly in the form of films and sheets, to lose certain of their liquid
30、 constituents when they are brought into contact with materials that have an affinity for plasticizers, andb) for studying the tendency to migrate of plasticizers contained in a resin or a series of resins, in one or more concentrations.In case b), standard compounds are prepared on the basis of a w
31、ell-characterized resin with well-defined ratios of plasticizer to resin.NOTE 2 When the absorbent sheets themselves contain a substance capable of migrating, simultaneous migrations can occur from the test specimens into the absorbent sheets and vice versa.The results may also be affected by the mi
32、gration of other constituents of the plastic material (for example, oligomers) or by the loss of any volatile constituents other than plasticizers from the plastic material or the absorbent layer.2 Normative referencesThe following documents are referred to in the text in such a way that some or all

37、st specimen cut from a sheet or plate of the material or from the finished product to be tested is placed in close contact with two sheets, capable of absorbing plasticizers. It is then subjected to heating under defined conditions. The loss in mass of the test specimen, theoretically equal to the i
38、ncrease in mass of the sheets, is a measure of the migration of the plasticizer.5 Apparatus5.1 Analytical balance, accurate to 0,001 g.5.2 Micrometer, accurate to 0,01 mm.5.3 Air circulating oven, capable of maintaining the temperature to within 2 C, in the range 50 C to 100 C.5.4 Glass plates, with
39、 plane surfaces, of sufficient size to cover the absorbent backing discs (5.6).5.5 Weights, of 5 kg.5.6 Absorbent backing discs, with an affinity for plasticizers, 60 mm 1 mm in diameter and at least 0,5 mm in thickness.The materials recommended for the test are: a standard rubber (according to ISO
40、4649), or polyethylene without additive, or polyvinyl acetate without plasticizer.In the case of a particular application, an absorbent backing disc of the material with which the plastic under test will be in contact when in service shall be used. The surface of the absorbent backing disc shall be
41、sufficiently smooth to ensure continuous contact with the test specimen.6 Test specimens6.1 The test specimens shall be in the form of discs 50 mm 1 mm in diameter and at least 0,5 mm in thickness, cut from a compression-moulded (in accordance with ISO 293) or injection-moulded (in accordance with I
42、SO 294-1 and ISO 294-3) sheet of suitable thickness.The surface of the test specimens shall be sufficiently smooth to ensure continuous contact with the absorbent backing discs (5.6).6.2 In the case of films, the test specimen of not less than 0,5 mm thickness shall be produced by pressing an adequa
43、te number of films at a suitable temperature for about 1 min.6.3 If the test is intended to determine the migration from a finished product, the latter shall be tested at a uniform thickness.DIN EN ISO 177:2017-05 EN ISO 177:2017 (E)6 6.4 If the product to be tested consists of a support (fabric, pa
44、per or other suitable material), coated on one face only by the spreading or calendering of a plasticized resin (such as fabrics coated with vinyl resins or with similar products), the test specimens shall consist of two discs cut from the material itself and superposed in such a way that the uncoat
45、ed surfaces of the support are touching and the plastic is situated on the other faces of the sandwich so formed.6.5 Three test specimens shall be tested for each material.7 ConditioningUnless otherwise specified, the test specimens and absorbent backing discs (5.6) shall be conditioned in one of th
46、e atmospheres specified in ISO 291.8 Procedure8.1 After conditioning, weigh the test specimens (see Clause 6) and the discs (5.6) to the nearest 0,001 g and determine their mean thickness to the nearest 0,01 mm.8.2 Place a test specimen of the material under test between two absorbent backing discs,
47、 in such a way that their axes coincide and the assembly forms a sandwich. Place the latter between two glass plates (5.4).8.3 If the test is intended to determine the characteristics of particular plasticizers, standard compounds of a specified composition shall be used, as agreed between the inter
48、ested parties.8.4 To equalize the distribution of pressure between the absorbent backing disc and the test specimen, a sheet of rubber shall be inserted between the absorbent backing disc and the glass plate. The absorbent backing disc shall be separated from the sheet of rubber by aluminium foil.8.5 Place one of the 5 kg weights (5.5) on the assembly of discs and plates to be tested and place the assembly in the oven (5.3), maintained a
