ANSI ISEA-201-2012 pdf download American National Standard for Classification of Insulating Apparel Used in Cold Work Environments
1 Scope
This standard establishes classification requirements for occupational apparel items worn in cold environments. The apparel items specified in this standard are passively insulated, i.e., designed to regulate body temperature of the wearer by inhibiting heat transfer away from the body. Specific criteria are included for thermal insulation (in units of clo) and thermal transport properties. The resistance to the deterioration of these properties due to laundering are assessed and classified accordingly.
The standard also includes garment care and labeling requirements and provides guidance on the selection of the apparel items based on given environments and activity levels. Specific apparel covered by this standard includes insulated or shell jackets, parkas, vests, coveralls, pants and insulated flame resistant occupational wear, as well as combinations thereof.
This standard does not address gloves, headwear, and footwear, although these items should be included in the prescribed cold weather ensemble in order to achieve functional protection. Apparel items which are actively heated or use phase change materials (PCMs) to regulate body temperature of the wearer by actively generating, adding, or releasing heat are not included in this standard.
2 Purpose
The purpose of this standard is to be a tool to assist garment selectors or specifiers in determining appropriate apparel items for cold ambient environments based on temperature and the activity of the wearer. It is also intended to assist garment manufacturers in selecting materials and performance of said apparel items (See Appendix A).
