Significance and Use
4.1 This practice can be used for the evaluation of the ROM of protective clothing ensembles worn under controlled conditions and can provide guidelines for the motion evaluation of PPE.
4.1.1 This practice utilizes a space large enough to allow users to move freely during the tasks and a chair and a stretcher to measure certain body joint mobility.
Note 1: Since required range of motion values will be related to the work task to be done while wearing the protective ensemble, the end user should decide meaningfulness of the information provided by this standard for the performance of their job.
4.2 This practice establishes general procedures for the evaluation based on the measurement of range of motion and subjective perceptions.
4.2.1 The data obtained can be used to evaluate the ROM of the test participant while wearing a protective clothing ensemble.
4.2.2 The data are also potentially useful in the research and development of advanced ensembles that are designed for optimal mobility and comfort or reduce strain on the wearer thereby reducing the potential injury associated with wearing the protective clothing ensemble.
4.2.3 The data are also potentially useful for first responder organizations to compare the ROM while wearing different ensembles.
4.2.4 This practice could also be used by consensus standards organizations in the development of ergonomic test criteria for protective ensembles.
4.3 Departures from the instructions in this practice have the potential to lead to significantly different test results. Technical knowledge concerning mobility of body joints, subjective evaluations, and testing practices is needed to evaluate which departures from the instructions given in this practice are significant. All departures must be reported with the results.
1.1 This practice specifies the test equipment and procedures for assessing ROM on subjects wearing a protective clothing ensemble.
1.2 This practice covers the ergonomic measurements of range of motion and subjective perceptions.
1.3 To increase safety during testing, this practice requires the use of human participants who meet specific health and physical fitness requirements.
1.4 This practice does not attempt to determine other clothing characteristics, such as thermal insulation and evaporative resistance of the protective clothing ensemble. Test Methods and can be used for these measurements.
1.5 The values stated in this standard shall be SI units.
1.6 It is the responsibility of the test laboratory to obtain the necessary and appropriate approval(s) required by their institution for conducting tests using human participants.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
