1、Designation: F 1849 07An American National StandardStandard Specification forHelmets Used in Short Track Speed Ice Skating (Not toInclude Hockey)1This standard is issued under the fixed designation F 1849; the number immediately following the designation indicates the year oforiginal adoption or, in

2、 the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers performance requirements forhelmets used by short track

3、speed ice skaters (excludinghockey). This specification recognizes the desirability of light-weight construction and ventilation; however, it is a perfor-mance standard and is not intended to restrict design.1.2 All testing and requirements of this specification shallbe in accordance with Test Metho

4、ds F 1446, except wherenoted herein.1.3 Partial utilization of this specification is prohibited. Anystatement of compliance with this specification must be acertification that the headgear meets all of the requirements ofthe specification in their entirety. A headgear that fails to meetany one of th

5、e requirements of this specification is consideredto have failed the specification, and shall not be sold with anyindication that it meets parts of the specification.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 This s

6、tandard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
