Ergonomics of the thermal environment - Determination of metabolic rate (ISO 8996:2021)

Ergonomics of the thermal environment - Determination of metabolic rate (ISO 8996:2021)

This document specifies different methods for the determination of metabolic rate in the context of ergonomics of the thermal working environment. It can also be used for other applications, e.g. the assessment of working practices, the energetic cost of specific jobs or sport activities and the total energy cost of an activity. The methods are classified in four levels of increasing accuracy: level 1, Screening, with a table giving examples of activities with low, moderate and high metabolic rates; level 2, Observation, where the metabolic rate is estimated by a time and motion study; level 3, Analysis, where the metabolic rate is estimated from heart rate recordings or accelerometers measurements; and level 4, Expertise, where more sophisticated techniques are described. The procedure to put into practice these methods is presented and the uncertainties are discussed.

Ergonomie der thermischen Umgebung - Bestimmung des körpereigenen Energieumsatzes (ISO 8996:2021)

Dieses Dokument legt unterschiedliche Verfahren für die Bestimmung des Energieumsatzes im Bereich der Ergonomie der thermischen Arbeitsumgebung fest. Es kann auch für andere Anwendungsgebiete, zum Beispiel für die Bewertung von Arbeitsverfahren, des Energieaufwands für spezielle Aufgaben oder Sportaktivitäten sowie des Gesamtenergieaufwands einer Tätigkeit angewendet werden. Die Verfahren werden in vier Stufen mit zunehmender Genauigkeit eingeteilt: Stufe 1, Screening mit einer Tabelle, die Beispiele für Aktivitäten mit geringem, mittlerem und hohem Energieumsatz angibt; Stufe 2, Beobachtung, wo der Energieumsatz mit einer Zeit- und Bewegungsstudie geschätzt wird; Stufe 3, Analyse, wo der Energieumsatz aufgrund von Aufzeichnungen der Herzfrequenz oder der Messungen von Beschleunigungsaufnehmern geschätzt wird; und Stufe 4, Expertise, wo anspruchsvollere Techniken beschrieben werden. Das Verfahren, um diese Methoden durchzuführen, wird dargestellt und die Unsicherheiten werden diskutiert.

Ergonomie de l'environnement thermique - Détermination du métabolisme énergétique (ISO 8996:2021)

Le présent document spécifie différentes méthodes visant à déterminer le métabolisme énergétique dans le domaine de l’ergonomie de l’environnement de travail thermique. Il peut cependant être également utilisé en vue d’autres applications, par exemple l’évaluation des pratiques de travail, le coût énergétique de travaux ou d’activités sportives spécifiques et le coût énergétique global d’une activité. Les méthodes sont classées en quatre niveaux de précision croissante: niveau 1, Typologies, avec un tableau donnant des exemples d’activités avec métabolismes énergétiques faibles, modérés et élevés; niveau 2, Observation, où le métabolisme énergétique est estimé par une étude des temps et des mouvements; niveau 3, Analyse, où le métabolisme énergétique est estimé à partir d’enregistrements de la fréquence cardiaque ou de mesures d’accéléromètres; et niveau 4, Expertise, où des techniques plus sophistiquées sont décrites. Le mode opératoire pour mettre en pratique ces méthodes est indiqué et les incertitudes sont examinées.

Ergonomija toplotnega okolja - Ugotavljanje presnovne toplote (ISO 8996:2021)

Ta dokument določa različne metode za ugotavljanje presnovne toplote v kontekstu ergonomije toplotnega delovnega okolja. Primeren je tudi za druge vrste uporabe, npr. ocenjevanje delovnih praks, energetskih stroškov za posamezno delovno mesto ali športno dejavnost in skupnih energetskih stroškov posamezne dejavnosti. Metode so razvrščene v štiri stopnje povečanja natančnosti: stopnja 1 – presejanje, s preglednico primerov dejavnosti z nizko, zmerno in visoko prenosno toploto; stopnja 2 – opazovanje, pri čemer se presnovna toplota oceni na podlagi študije časa in gibanja; stopnja 3 – analiza, pri čemer se presnovna toplota oceni na podlagi zapisov srčnega utripa ali meritev merilnikov pospeška; ter stopnja 4 – strokovno znanje, pri čemer so opisane kompleksnejše tehnike. Predstavljen je postopek uporabe teh metod v praksi in obravnavane so negotovosti v zvezi s tem.

General requirements for establishing anthropometric databases (ISO 15535:2023)
SIST EN ISO 15535:2024

This document specifies general requirements for anthropometric databases and their associated reports that contain measurements taken in accordance with ISO 7250-1.
It provides necessary information, such as characteristics of the user population, sampling methods, measurement items and statistics, to make international comparison possible among various population segments. The population segments specified in this document are people who are able to hold the postures specified in ISO 7250-1.
NOTE            The traditional anthropometry defined in ISO 7250-1 is considered to be a necessary complement to 3-D methods, which are used in some countries. Scanned data are verified according to the definitions given in ISO 7250-1 (see ISO 20685-1). State-of-the-art software allows integration of traditional anthropometric measures with those obtained by 3-D imaging.

Ergonomics - 3-D scanning methodologies for internationally compatible anthropometric databases - Part 2: Evaluation protocol of surface shape and repeatability of relative landmark positions (ISO 20685-2:2023)
SIST EN ISO 20685-2:2023

This document establishes protocols for testing of 3-D surface-scanning systems in the acquisition of human body shape data and measurements. It does not apply to instruments that measure the motion of individual landmarks.
While mainly concerned with whole-body scanners, this document is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). It applies to body scanners that measure the human body in a single view. When a hand-held scanner is evaluated, the human operator can contribute to the overall error. When systems are evaluated in which the participant is rotated, movement artefacts can be introduced; these can also contribute to the overall error. This document applies to the landmark positions determined by an anthropometrist. It does not apply to landmark positions automatically calculated by software from the point cloud.
The quality of surface shape of the human body and landmark positions is influenced by the performance of scanner systems and humans, including measurers and participants. This document addresses the performance of scanner systems by using artefacts rather than human participants as test objects.
Traditional instruments are required to be accurate to the millimetre. Their accuracy can be verified by comparing the instrument with a scale calibrated according to an international standard of length. To verify or specify the accuracy of body scanners, a calibrated test object with known form and size is used.
The intended audience is those who use 3-D body scanners to create 3-D anthropometric databases, the users of these data, and body scanner designers and manufacturers. This document intends to provide the basis for agreement on the performance of body scanners between scanner users and scanner providers as well as between 3-D anthropometric database providers and data users.

Ergonomics of the thermal environment - Analytical determination and interpretation of heat stress using calculation of the predicted heat strain (ISO 7933:2023)
SIST EN ISO 7933:2023

This document describes a model [the predicted heat strain (PHS) model] for the analytical determination and interpretation of the thermal stress (in terms of water loss and rectal temperature) experienced by an average person in a hot environment and determines the maximum allowable exposure times within which the physiological strain is acceptable for 95 % of the exposed population (the maximum tolerable rectal temperature and the maximum tolerable water loss are not exceeded by 95 % of the exposed people).
The various terms used in this prediction model and, in particular, in the heat balance, show the influence of the different physical parameters of the environment on the thermal stress experienced by the average person. In this way, this document makes it possible to determine which parameter or group of parameters can be changed, and to what extent, in order to reduce the risk of excessive physiological strain.
In its present form, this method of assessment is not applicable to cases where special protective clothing (e.g. fully reflective clothing, active cooling and ventilation, impermeable coveralls) is worn.
This document does not predict the physiological response of an individual person, but only considers average persons in good health and fit for the work they perform. It is therefore intended to be used by, among others, ergonomists and industrial hygienists, as the outcomes can require expert interpretations. Recommendations about how and when to use this model are given in ISO 8025.

Ergonomics - Ergonomics of PPE ensembles
SIST EN 17558:2024

This document contains test methods for comparing the performance of different ensembles as part of any PPE selection process.
This document does not replace the product standards for the certification of individual items of PPE. It specifies the testing of individual items of PPE as an ensemble, so that the interactions between the individual items of PPE can be evaluated and any adverse interactions between the individual items of PPE, the user and the environment can be identified.
It specifies requirements for testing by either assessing the performance of a PPE ensemble against a benchmark condition (i.e. benchmark testing) or assessing the performance of two or more PPE ensembles against each other (i.e. comparative testing).
This document incorporates examples of laboratory and field tests. It can also be used to assess the performance regarding the ergonomics of an ensemble that incorporates an item of PPE that has never before been incorporated into an ensemble, and the listed methods can be combined into dedicated test batteries for evaluating that ensemble.

CEN ISO/TS 9241-430:2023(Main)
Ergonomics of human-system interaction - Part 430: Recommendations for the design of non-touch gestural input for the reduction of biomechanical stress (ISO/TS 9241-430:2021)
SIST-TS CEN ISO/TS 9241-430:2023

This document provides guidance on the design, selection and optimization of non-contacting hand and arm gestures for human-computer interaction. It addresses the assessment of usability and fatigue associated with different gesture set designs and provides recommendations for approaches to evaluating the design and selection of gestures. This document also provides guidance on the documentation of the process for selecting gesture sets.
This document applies to gestures expressed by humans. It does not consider the technology for detecting gestures or the system response when interpreting a gesture. Non-contacting hand gestures can be used for input in a variety of settings, including the workplace or in public settings and when using fixed screens, mobile, virtual reality, augmented reality or mixed-mode reality devices.
Some limitations of this document are:
—    The scope is limited to non-contacting gestures and does not include other forms of inputs. For example, combining gesture with speech, gaze or head position can reduce input error, but these combinations are not considered here.
—    The scope is limited to non-contacting arm, hand and finger gestures, either unilateral (one-handed) or bilateral (two-handed).
—    The scope assumes that all technological constraints are surmountable. Therefore, there is no consideration of technological limitations with interpreting ultra-rapid gestures, gestures performed by people of different skin tones or wearing different colours or patterns of clothing.
—    The scope is limited to UI-based command-and-control human computer interaction (HCI) tasks and does not include gaming scenarios, although the traversal of in-game menus and navigation of UI elements is within scope.
—    The scope does not include HCI tasks for which an obviously more optimal input method exists. For example, speech input is superior for inputting text than gesture input.
—    The scope includes virtual reality (VR), augmented reality (AR) and mixed reality (MR) and the use of head-mounted displays (HMDs).
—    The scope does not include the discoverability of gestures but does include the learnability and memorability of gestures. It is assumed that product documentation and tutorials will adequately educate end users about which gestures are possible. Therefore, assessing gesture discoverability is not a primary goal of the recommendations in this document.

Principles for selecting and using test persons for testing anthropometric aspects of industrial products and designs (ISO 15537:2022)
SIST EN ISO 15537:2022

This document establishes methods for determining the composition of groups of persons whose anthropometric characteristics are to be representative of the intended user population of any specific object under test.
This document is applicable to the testing of anthropometric aspects of industrial products and designs having direct contact with the human body or dependent on human body measurements, such as machinery, work equipment, personal protective equipment (PPE), consumer goods, working spaces, architectural details or transportation equipment.
This document is also applicable to the testing of such safety aspects of products that are dependent on human body measurements. It does not deal with other aspects of the task or other requirements, such as perception of information (except geometrical arrangement of the viewing targets) and the use of controls (except their geometrical placement).
Although this document deals with selecting test persons from an anthropometric perspective, similar general principles can be applied for other test variables, e.g. biomechanical aspects.
