Standards Development

Scope

This part of ISO 11228 establishes ergonomic recommendations for repetitive work tasks involving repetitive movements and exertions of the upper extremity. It provides guidance on the identification and assessment of risk factors commonly associated with repetitive movements and exertions of the upper limbs, thereby allowing evaluation of the related health risks to the working population. The recommendations apply to the adult working population and are intended to give reasonable protection for nearly all healthy adults. Those recommendations concerning health risks and control measures are mainly based on research involving in North American and European populations and how work methods affect musculoskeletal loading, discomfort/pain and endurance/fatigue. These recommendations can be used for guidance purposes. Countries may generate their own recommendations based on studies on native populations. For the evaluation of working postures, refer to ISO 11226.

It should be noted that this standard does not have a mass threshold or limit. However, if the masses handled are 3 kg or more, the user is directed to also consult ISO 11228-1 Ergonomics – Manual handling – Part 1: Lifting, lowering and carrying.

This part of ISO 11228 is intended to provide information for all those involved in the design or redesign of work, jobs and products (e.g. machinery).

This document does not address the manual handling of objects while using lift-assistive devices such as exoskeletons and does not address the needs of pregnant women or persons with disabilities.
