2、pproved February 17, 2012 American National Standards Institute, Inc. ii American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the cons

3、umer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether they have approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American Nation

4、al Standards are subject to periodic review and users are cautioned to obtain the latest editions. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no persons shall have the right or

5、authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be

6、taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute. Published by International Safety Eq

8、he United States of America iii Foreword (This Foreword is not part of American National Standard ANSI/ISEA 201-2012) The contribution of clothing to maintain consistent comfortable temperatures for the wearer is an important factor in productivity, endurance and safety in performing a given activit

9、y. In cold weather particularly, a clothing ensemble must meet a number of requirements. It must provide the required level of insulation for the comfort and protection of the wearer in the exposure environment. The clothing must maintain the level of “as new” performance reasonably throughout the e

10、xpected useful lifetime of the garment/ensemble. In addition, the garments other performance properties such as warmth to weight, thickness to weight, warmth to thickness, breathability, and bending modulus must be considered to optimize the ensemble for comfort and performance in the chosen activit

11、y. This standard provides a tool for rating insulative garments for intrinsic insulation value (clo units) in six performance categories and for temperature, with minimal restriction to design options. The ANSI/ISEA 201-2012 standard also requires that a certified garment will retain its insulative

12、properties over a known period of its useful lifetime as a function of the number of cycles of its recommended cleaning procedure, to provide reliable lasting protection to the wearer. Appendix material provides direction to a specifier or user on how to use this and other related standards to deter

13、mine an appropriate baseline for specifying intrinsic insulation value for a given activity level and exposure condition. Garments classified to ANSI/ISEA 201-2012 may comply with other standards addressing additional hazards such as low visibility, heat and flame exposures, or hazards related to ar

14、c flash. The existence of competing hazards may greatly affect the choices of materials for the ensemble. This standard was processed and approved using consensus procedures prescribed by the American National Standards Institute. The following organizations were contacted prior to the approval of t

15、his standard. Inclusion in this list does not necessarily imply that the organization concurred with the submittal of the proposed standard to ANSI.

20、ork 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 fr

21、om 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

22、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

23、. 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

24、 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 o

25、f the wearer. It is also intended to assist garment manufacturers in selecting materials and performance of said apparel items (See Appendix A). 3 Compliance 3.1 Durability class as a function of laundry procedure and number of cycles shall be assigned in accordance with Section 7. The form in Appen

26、dix B1 shall be used. 3.2 Thermal classification (of finished intact insulating apparel shall be certified to verify performance to the requirements specified in Section 8. The form in Appendix B2 shall be used. 3.3 All certificates and test reports that verify the performance of finished intact ins

27、ulating apparel shall be retained by the manufacturer and be made available upon request. 3.4 A garment compliance certificate shall be developed for all models produced by each manufacturer, using the format in Appendix B3.
