Ergonomics of the thermal environment - Instruments for measuring and monitoring physical quantities (ISO/DIS 7726:2023)

Ergonomie der thermischen Umgebung - Instrumente zur Messung und Überwachung physikalischer Größen (ISO/DIS 7726:2023)

Diese Internationale Norm legt die Mindestanforderungen an Instrumente zur Messung physikalischer Größen zur Beschreibung einer thermischen Umgebung sowie Verfahren zur Messung der physikalischen Größen dieser Umgebung fest.
Zweck der Norm ist es lediglich, das Verfahren zu normen, mit dem die Daten zur Bestimmung von physikalischen Größen erfasst werden. In anderen Internationalen Normen werden die Verfahren detailliert beschrieben, die auf den mit dieser Norm ermittelten Daten basieren.
Diese Internationale Norm dient als Referenz bei der Erarbeitung
a)   von Festlegungen für Hersteller und Benutzer von Instrumenten zur Messung der physikalischen Größen der Umgebung,
b)   eines schriftlichen Vertrags zwischen zwei Parteien für die Messung dieser Größen.
Sie gilt für die Auswirkung heißer, neutraler, angenehmer oder kalter Umgebungen auf den Menschen. Diese Norm wird in Fällen angewendet, in denen die Behaglichkeit oder die Belastung des Menschen das Hauptanliegen sind, sie darf von anderen Normen ersetzt werden.

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. www.iso.org/directives

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
