ISO/TS 13732-2:2001 熱環境の人間工学—表面との接触に対する人間の反応を評価する方法—パート2：中程度の温度での表面との人間の接触 | ページ 2

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document:

• an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote;
• an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote.

An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be transformed into an International Standard.

Attention is drawn to the possibility that some of the elements of this part of ISO/TS 13732 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO/TS 13732-2 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 5, Ergonomics of the physical environment.

ISO/TS 13732 consists of the following parts, under the general title Ergonomics of the thermal environment — Methods for the assessment of human responses to contact with surfaces:

• Part 1: Human contact with hot surfaces
• Part 2: Human contact with surfaces at moderate temperature

Introduction

Contact between bare skin and solid surfaces may cause thermal discomfort depending upon the part of the body in contact, the temperature of the material and the type of material. It may also increase the risk when handling machines, hand tools and in the home. Bare skin in contact with metal at room temperatures may cause a cold sensation, while contact with wood may feel comfortable. The sensation and discomfort felt should be taken into account when designing and constructing handrails, handles of vehicles, hand tools, floor materials in spaces where people walk with bare feet and children play on the floor. In this part of ISO/TS 13732, some fundamental ergonomic data are presented to help the prediction of thermal sensation and discomfort caused by contact with surfaces in the moderate temperature range.

1 Scope

This part of ISO/TS 13732 presents principles and methods for predicting the thermal sensation and degree of discomfort for people where parts of the body are in contact with solid surfaces at moderate surface temperatures (approximately 10 °C to 40 °C).

It deals with the thermal sensation for contacts of the hand, foot and for the sitting position on the floor.
