1.1 本规范涵盖了用于空手道、武术和跆拳道等战斗性运动的训练和比赛的头部防护性能要求，其中参与者之间可能会重复正常接触，但仅限于不会造成伤害的水平。这些活动通常在温度适中的室内或室外环境中进行。本规范认可了轻质流线型结构和通风的可取性； 然而，它是一个性能规范，并不是为了限制设计。 1.2 本规范的所有测试和要求应符合测试方法 F1446 ，除非本规范另有说明。 1.3 禁止部分使用本标准。符合本规范的任何声明均应证明产品整体符合本规范的所有要求。不符合本规范任何一项要求的产品被视为不符合本规范，不得在分销或销售时显示其符合本规范的任何部分。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 以下安全警告适用于本文所述的化学、机械或物理或其组合的测试方法，并专门针对执行测试的人员（旨在向他们提供在进行测试时采取适当预防措施的通知）: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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.
