10、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 subject for which a technical committee has been esta
11、blished 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) on all matters of electrotechnical standardiza
12、tion.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 noted. This document was drafted in accordance wit
13、h the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

18、sign ranges for use in product standards1 ScopeThis part of ISO 7250 provides worldwide and regional tables of design ranges for use with product standards for equipment design and safety that require ISO 7250 body measurement data input.Anthropometric data for technological design are used and pres
19、ented in many standards. However, there is currently no systematic way to update and revise those values in a timely manner, as the body sizes and variation of member body populations change with time. Further, the schedule of member body anthropometric surveys varies widely. Many industrial product
20、s are developed for regional or worldwide markets without a clear presentation of regional and worldwide ISO 7250 design ranges. Users of standards require the most appropriate body measurement values for their intended applications.Together with ISO/TR 7250-2, which serves as a continuously updated
21、 data source for most current anthropometric data from individual member bodies, this part of ISO 7250 provides a periodically updated data source for worldwide and regional design ranges, with guidance on sex differences. This part of ISO 7250 is intended as the single source of anthropometric data
22、 for equipment design guidance in standards.While there are sources for individual member body data in ISO/TR 7250-2, most standards do not use individual member body data for technological specification. This part of ISO 7250 is to be used whenever worldwide or regional anthropometric data are need
23、ed. In cases when there are no suitable measurements in this part of ISO 7250, the methods and justifications used in arriving at regional and worldwide values from the body measurement data of individual populations can be used with suitable measurement data.The scope of this part of ISO 7250 is li
24、mited to the presentation of univariate design ranges of the type currently utilized in product standards (e.g. P1, P5, P95, and P99) and does not address shortcomings of using those values in multivariate designs. A separate standard on multivariate design is in preparation. In addition, this part
25、of ISO 7250 does not address body measurements used in product standards that are not defined in ISO 7250-1. The methods used in developing this part of ISO 7250 do not take into account the population size or sampling methodology of the member bodies, so statistical values from a sparsely populated
26、 member body could set regional or worldwide upper or lower limits. The reader is referred to ISO/TR 7250-2 for details on sampling methods used in national surveys.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable f

29、directly related to ISO/TR 7250-2.Design ranges are specified as smallest to largest 1st to 99th and 5th to 95th percentile value observed in national populations. Each percentile value in a design range comes from a single member body. Typically, product design requirements specify a smallest to la
30、rgest range of values to be accommodated. However, some product standards specify medium size or midrange values, so midrange estimates are also provided here.The worldwide ranges specified in this part of ISO 7250 are normative for product standards. However, some users of this part of 7250 may be
31、developing products designed for a more focused, regional market. For this reason, a method is presented for creating regional design ranges from individual member body data presented in ISO/TR 7250-2. Examples of this process are shown in informative Annex A. For the anthropometric data used in der
32、iving regional and worldwide ranges, the procedure and information for acquiring these data directly follow from the process described in ISO/TR 7250-2. The process of specifying design ranges defined in this part of ISO 7250 starts from the individual member body data presented in ISO/TR 7250-2.Sim
33、ilarly, for many applications, user accommodation is maximized by considering male and female design dimensions separately. For example, maximum accommodation would be achieved by designing to a range that extends from the smallest 5th percentile value, male or female, to the largest 95th percentile
34、 value, male or female. Annex B shows the results of this procedure and should be used when the largest accommodation range is desired.4 Procedures for establishing design ranges4.1 Worldwide rangesAnthropometric data are collected in many countries in the world. These anthropometric surveys vary ma
35、rkedly in quality, frequency, methodology, and purpose. In order to produce normative design ranges, it is critical to use anthropometric data that meet only the highest standards of representativeness and reliability. In addition, ISO standards are fundamentally a service for ISO member bodies. The
36、refore, the worldwide ranges presented in this part of ISO 7250 are derived from national populations of ISO member bodies presented in ISO/TR 7250-2. ISO/TR 7250-2 data are known to be consistent with ISO 7250-1 measurement definitions and protocols and ISO 15535 anthropometric database methods, an
37、d ISO/TR 7250-2 statistics have been reviewed and checked with member bodies for accuracy and reliability.For some anthropometric dimensions, the population distribution is bi-modal by sex. This means that the male mean and female mean are separated. While the male and female distributions overlap,
38、there are significant portions of the combined distribution that are totally male or totally female. Using a “total” 5th percentile value, therefore, may exclude 5 % of the total population but it may exclude 30 % of the female population. The effect is magnified when the sex distributions of the po
39、pulations are significantly unequal, for example, in a military population which might be overwhelmingly male or in a nursing population which might be overwhelmingly female. When specific work forces are differentially male or differentially female, the “total” statistics may be significantly unrep
40、resentative of a particular work force even if they accurately represent the national population. Using a pooled malefemale population, P5 and P95 values for design for these situations will result in unequal burdens of disaccommodation between the sexes. In such cases, using separated male and fema
41、le design values comes closer to achieving gender-parity in the final design.The design ranges in Clause 5 contain male values, female values and “total” values. The sample sizes are listed so it is clear that different numbers of males and females were measured in the anthropometric surveys that ar
42、e found in ISO/TR 7250-2. The sex ratios in the sample may or may not represent the sex ratios in the working age population of the member bodies contributing data. Using “total” statistics as design values may be justified in certain specific cases but in general, male and female design values 2 IS
43、O 2015 All rights reservedBS ISO 7250-3:2015ISO 7250-3:2015(E)should be used separately in product or workspace design in order to ensure that both men and women are equally accommodated.In Clause 5, the worldwide P1 value represents the smallest 1st percentile observed among all the member bodies w
44、ith data presented in ISO/TR 7250-2. The worldwide P5 value represents the smallest 5th percentile observed among all the member bodies with data presented in ISO/TR 7250-2. The worldwide P95 value represents the largest 95th percentile observed among all the member bodies with data presented in ISO
45、/TR 7250-2. The worldwide P99 value represents the largest 99th percentile observed among all the member bodies with data presented in ISO/TR 7250-2. Thus, the values in the tables are based on particular surveys and only provide estimates for particular populations. The statistical confidence in th
46、e more extreme percentiles, e.g. P1 and P99, is much lower than it is for percentiles closer to the mean.In some cases, the smallest or largest percentile values in ISO/TR 7250-2 have been identified as either unusual or derived from body scan data not validated in accordance with ISO 20685. In such
47、 cases, a more reliable value may be chosen to set the worldwide design limit.The midrange estimates in this part of ISO 7250 are calculated as the midpoints of the interval between the worldwide P5 and P95 estimates. The user is cautioned that these midrange estimates, while centrally located betwe
48、en the P5 and P95 estimates, are not equivalent to statistical medians. They may not represent medium-sized males or females in any particular population.4.2 Regional rangesRegional design ranges illustrated in Annex A are informative in nature. In general, regional ranges are derived from only the
49、member body data presented in ISO/TR 7250-2. In the case of defining regional ranges for the European region, existing published CEN standards were used as a starting point and where individual European member body data in ISO/TR 7250-2 exceed the published CEN standard ranges, ISO/TR 7250-2 limits were used to form the new European regional ranges.The regional P1 value represents the smallest 1st percentile observed among all the member bodies with data presented in ISO/TR 7250-2. The regional P5 value represents the smallest 5th percentile observed amon
