9、es). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and
10、non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are des
11、cribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents 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
12、 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 any or all such patent rights.

This second edition cancels and replaces the first edition (ISO 5971:1981), which has been technically revised in order to align with ISO 8559-1:2017 and ISO 8559-2:2017 and include the following main changes: informative Annex
16、 A added on rationale related to survey data on body dimensions; informative Annex B added including updated examples of tight size designation.iv ISO 2017 All rights reserved BS ISO 5971:2017 Size designation of clothes Tights 1 Scope This document establishes a system for designating the sizes of
17、tights. The system is based on three criteria: identification of dimensions; description of the methods of determining size designations from survey data; and indication of size designations for garment labelling. Examples of size designations are given in Annex B. NOTE Tights are sometimes called b
18、y other names, e.g. “pantyhose”. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

21、 tights The control dimensions of tights are usually as follows: 1) height as the primary dimension and hip girth and/or body mass as the secondary dimension; 2) hip girth as the primary dimension and height as the secondary dimension. NOTE There is a close correlation between hip girth and body mas
22、s (see Annex A). Body measurements are determined in accordance with ISO 8559-1 and control dimensions in accordance with ISO 8559-2. INTERNATIONAL ST ANDARD ISO 5971:2017(E) ISO 2017 All rights reserved 1 BS ISO 5971:2017 ISO 5971:2017(E) 4.2 Survey data The size designation is obtained from a grid
23、 (see Annex B) having height and hip girth or height and body mass for co-ordinates. Each cell represents the fraction of population matching either both dimensions or height and body mass. A white empty cell means that it does not correspond to anybody or only to a very low percentage of people (fo
24、r distribution of the population, see Annex A). By plotting the intended wearers height against hip girth or body mass as presented on the grid, the appropriate size designation can be determined. The size designation may be indicated by colour, by number or by any other suitable means. Instead of u
25、sing a detailed grid, a simpler chart may be provided to the consumer with a range of height/hip girth or height/body mass (see Annex B). The cartography and the number of sizes will differ from one supplier to another, as it will depend on the deformation behaviour and the extensibility of the prod
26、uct as well as on the intended market of wearers. 4.3 Marking, labelling and packaging The size designation shall be indicated clearly, conspicuously and in a plainly identifiable form on the packaging or label. The labelling examples given in the different figures of Annex B illustrate methods of d
27、etermining and indicating the size which is appropriate to the control dimensions of the intended wearer.2 ISO 2017 All rights reserved BS ISO 5971:2017 ISO 5971:2017(E) Annex A (informative) Rationale To build a grid, the first co-ordinate is usually the hip girth or the height (there is a close co
28、rrelation between the height and the inside leg length). If the first dimension is the hip girth, the second one is the height. If the first dimension is the height, the second co-ordinate is either the hip girth or the body mass. A close correlation has been found between both. As the consumer is m
29、uch more familiar with the body mass than the hip girth, the grids height/body mass are more commonly used on the market. EXAMPLE 1 Data from national or specific sizing surveys give the distribution of the population in the different cells of the grid (dimensions in centimetres): Height Hip girth 7

33、and the limits of the co-ordinates according to the morphology of the intended wearers. The number of different sizes within the grid often depends on the extensibility of the product; when a more stretchy material is used the number of sizes required can be reduced.4 ISO 2017 All rights reserved BS
34、 ISO 5971:2017 ISO 5971:2017(E) Annex B (informative) Examples of size grids or tables B.1 Examples with grids B.1.1 General Different sizes often follow diagonal lines within the grid because of the deformation behaviour of the products. In the first example, height is used as the primary dimension
35、 and body mass as the secondary dimension.
