BS ISO 7250-3:2015 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 presented 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 products 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 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 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 needed. 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 limited 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 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 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.Cross References:ISO 7250-1ISO/TR 7250-2ISO 15535ISO 20685All current amendments available at time of purchase are included with the purchase of this document.
