5.1 Sizing 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 may promote injury.

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

5.3 This 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 hazardous thermal exposures may exist.

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

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

1.3 This practice provides a standard means for measuring human body dimensions for the selection and ordering shirts and trousers.

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

1.5 This 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.

1.6 The 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.

1.7 This 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 that may be related to the fit of uniforms or protective clothing.

1.8 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Note 1 .
