Foreword

ISO (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 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 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 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 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. Details of

Introduction

The use of interactive systems takes place within a physical environment. The design of the physical

environment is decisive with regard to the outcome of the interaction between a variety of sizes of

users and the physical environment. As described in the system concept of ISO 26800, the physical

environment is embedded in an organizational and a social and cultural environment.

This document deals with the physical environment in which a physically diverse user group is assigned

to one or more workplaces, or spatial environments, to accomplish a task. The entirety of the spatial

environments assigned to a user is called environment of use. The relevant physical attributes of the

environment of use include issues such as air quality, thermal conditions, lighting, noise, spatial layout

and furniture. Specifically, this document discusses concepts for the spatial layout of workplaces so

that they match the physical anthropometric characteristics of the intended user population.

3.6
weighting

assignment of a statistically determined multiplier to an individual’s anthropometric data in order to

reflect its relative importance in making the sample representative of the intended user population’s

anthropometry
4 Accommodation estimates are statistical inferences based on samples drawn
from the intended user population
4.1 Population samples
4.1.1 Samples

In order to estimate anthropometric accommodation, the intended user population needs to be defined.

For example, Japanese adult civilians between the ages of 18 and 70, or all Finnish children between the

age of 0 months and 24 months.

The sample should be large enough to be statistically representative of the intended user population.

Often, the extremes of the data, the largest or smallest measurements, are of great interest to designers.

The sample should be large enough that those individuals whose measurements are in the extremes are

well represented in terms of count, thus avoiding over-reliance on too few individuals in the extremes of

[4]

the measurement distribution. According to the BIFMA G1 Guideline (BIFMA 2013) , “typically 1 000

or more individuals are needed for each gender to ensure good precision in the tails of the distribution

where the design decisions are made”.

Similarly, the sample should accurately reflect the demographics of the intended user population.

For example, a sample of anthropometric measurements of military personnel are generally not

representative of the civilian population as they are based on younger individuals who are likely fitter

and leaner than the civilian population from which the military are drawn.
4.1.2 Weighting

In some cases, the sample of anthropometric data does not exactly match the demography of the

intended users. For example, military data often do not exactly match civilian data on variables such

as height, mass and age. A practical solution is to statistically weight individuals within the sample in

[7] [6]

proportion to their representation in the population of intended users . However, as Gordon has

emphasized, the technique of statistically weighting the sample data is useful in representing the target

population, but its utility does not extend to intended user populations that differ from the sample.

For example, there are sufficient differences in the range of height between the Korean and Dutch

populations that one cannot be weighted to represent the other.
4.2 Univariate accommodation estimates

The simplest accommodation estimates are those where only one variable, such as height, is involved.

In such cases, a percentile value gives a useful estimate of accommodation. For example, a designer

can want to design the ceiling of a room in an air terminal so that it provides a 20-cm clearance above

the heads of at least 95 % of all males from anywhere in the world. Then, a design height that is 20 cm

greater than the greatest 95th percentile value of males’ height in ISO/TR 7250-2 would reasonably be

expected to accommodate at least 95 % of all males worldwide. An even greater proportion of females

would be accommodated as men are generally taller than women.

NOTE The air terminal designer notes that the tallest males in the ISO/TR 7250-2 data set are from the

Netherlands, and that the 95 percentile value for their height is 195,9 cm. The designer adds 20 cm to the

95th percentile value and is reasonably confident that a ceiling height of 215,9 cm comfortably accommodates at

least 95 % of all male travellers.

A similar accommodation estimate can be made using a 5th percentile value. C
