5.1Sizing is a critical factor that must be considered when selecting and using protective clothing. Properly sized garments add to the safety and performance of wearer by not restricting movement. A work uniform that restricts movement or exposes skin to hazardous environments will result in lost efficiency and less protection.

5.2In those cases where work uniforms become an element of a multi-layered protective ensemble, it is essential that uniform fit does not restrict the wearers movements or interfere with the fit and use of other safety-related clothing and equipment.

5.3This practice can be used for selecting the proper size and fit of work uniforms for fire and rescue personnel and personnel in other occupations where the potential exists for hazardous thermal exposures.

5.4This practice is not intended to apply to multi-layered thermal protective clothing, such as firefighter protective clothing, where other factors apply to the fit relative to its performance.

1.1This practice is intended to assist in size selection of work uniforms for fire and rescue services personnel and workers who have the potential to be exposed to thermal hazards. Work uniform ensembles consist of a shirt and trouser apparel combination.

1.2This practice is applicable to uniforms for both male and female personnel.

1.3This practice provides an internationally recognized means for measuring human body dimensions for the selection and ordering of shirts, trousers, and one-piece coveralls.

1.4This practice provides a means for evaluating the fit of selected uniform sizes.

1.5This practice provides a standard list of textile and apparel terminology specific to the clothing industry which is used in determining size and fit of garments. This vocabulary will be useful in communications between buyers and sellers.

1.6The values stated in SI units are to be regarded as standard. The inch-pound equivalents given in parentheses are for information only and may be approximate.

1.7This standard is not intended for use in evaluating the fire-resistive performance or durability of work uniforms. In addition, this practice does not provide a means to quantify the likelihood of human injuries related to the fit of uniforms or protective clothing.

1.8This 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. Specific precautionary statements are given in Section 7.

1.9This 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.
