ASTM F2397-18

1.1 This specification covers performance requirements for head protection used for training and competition in combative sports such as karate, wushu, and taekwondo, where normal contact between participants may be repeated, but is limited to a level that is not intended to produce injury. These activities typically take place in indoor or outdoor environments where the temperature is moderate. This specification recognizes the desirability of a lightweight and streamlined construction, and ventilation; however, it is a performance specification, and is not intended to restrict design.

1.2 All testing and requirements of this specification shall be in accordance with Test Methods F1446, except where noted in this specification.

1.3 Partial utilization of this standard is prohibited. Any statement of compliance with this specification shall be a certification that the product meets all of the requirements of the specification in its entirety. A product that fails to meet any one of the requirements of this specification is considered to have failed the specification, and shall not be distributed or sold with any indication that it meets parts of the specification.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 The following safety caveat applies to the chemical, mechanical, or physical, or a combination thereof, test methods described herein and is meant specifically for those performing the tests (in an effort to provide them with notice to take the appropriate precautions when conducting the tests): 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This 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.
