1.1 本规程为覆盖躯干的软抗弹道或抗刺伤防弹衣或两者提供了测量和装配指南。正确测量佩戴者并为其配备护甲是必要的，以获得躯干和重要器官的充分覆盖，同时允许军官操作所需的全方位运动。 1.2 这一做法主要针对执法和惩戒官员，并针对穿着制服的男性和女性的可隐藏（正常职责）防弹衣的测量和适合性。 本规程仅涉及由包含在载体内的前后防护板组成的防弹衣，该载体将防护板定位并固定在躯干上。 1.3 该实践可用于培训个人正确的测量技术，并培训佩戴者正确佩戴护甲。 1.4 第节提供了测量指南 5. 这种做法。 1.5 第节提供了卷尺的使用指南 6. 这种做法。 1.6 第节提供了定型背心的使用指南 7. 这种做法。 1.7 第节提供了个人装甲匹配评估 8. 供佩戴者使用。 1.8 单位- 本规程中规定的英制单位与美国防弹界使用的测量单位一致。括号中给出了国际单位制的近似值。 1.9 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。 1.10 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。 ====意义和用途====== 4.1 适当尺寸和安装的护甲在不限制移动的情况下提供保护，从而提高佩戴者的安全性和性能。拥有合适的防弹衣首先要有合适而准确的测量。本规程的测量指南将促进整个防弹衣行业测量的一致性，并帮助佩戴者了解正确的测量。 4.2 精确的测量不一定能得到合适的装甲，因此本实践进一步提供了井的描述- 穿戴者可以自行完成的个人护甲匹配评估。 4.3 测量和装配指南专门针对军官规定的前后护甲板侧面重叠的要求，将袖孔开口最小化，消除前后护甲板之间的任何“V”形间隙（或类似间隙），并从大约“2”处提供前躯干的垂直覆盖 nd公司 制服衬衫纽扣的指宽为2至3指，高于工作腰带。”在制定本规程和定义可对任何个人进行一致测量时，考虑了这些要求。 4.4 本规程描述了佩戴者的前、后和侧面的测量，以及周长测量，以实现前面板和后面板的适当尺寸以及完整护甲的适当配合。 4.5 该实践可用于培训个人正确的测量技术，并培训佩戴者正确佩戴护甲。

1.1 This practice provides measurement and fit guidance for soft ballistic-resistant or stab-resistant body armor, or both, covering the torso. Proper measurement of the wearer and fitting of armor to that individual are necessary to obtain sufficient coverage of the torso and vital organs while allowing the full range of motion required for officer operations. 1.2 This practice is primarily directed toward law enforcement and corrections officers and addresses measurements for and fit of concealable (normal duty) body armor worn under or over the uniform for both male and female wearers. This practice addresses only body armor composed of front and back protective panels contained within a carrier that positions and holds the panels on the torso. 1.3 This practice can be used to train individuals on proper measurement techniques and to train wearers on proper fitting of body armor. 1.4 Measurement guidance is provided in Section 5 of this practice. 1.5 Guidance for use of a tape measure is provided in Section 6 of this practice. 1.6 Guidance for use of sizing vests is provided in Section 7 of this practice. 1.7 A personal armor fit assessment is provided in Section 8 for use by wearers. 1.8 Units— English units are specified in this practice to be consistent with measurement units used in the United States body armor community. Approximate values in SI units are given in parentheses. 1.9 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. 1.10 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. ====== Significance And Use ====== 4.1 Properly sized and fitted body armor enhances the safety and performance of the wearer by providing protection while not restricting movement. Having body armor that fits well begins with appropriate and accurate measurements. The measurement guidance of this practice will facilitate consistency of measurement across the body armor industry and will help wearers understand proper measurements. 4.2 Accurate measurements do not necessarily result in well-fitting armor, so this practice goes a step further by providing a description of well-fitting armor along with a personal armor fit assessment that the wearer can do for himself/herself. 4.3 The measurement and fitting guidance specifically addresses officer-stated requirements for side overlap of front and back body armor panels, minimizing the armhole opening, eliminating any “V” gap (or similar) between the front and back panels, and providing vertical coverage on the front torso from approximately the “2 nd uniform shirt button to 2 to 3 finger widths above duty belt.” Those requirements were considered in the development of this practice and the definition of measurements that can be consistently made for any individual. 4.4 This practice describes measurements for the front, back, and sides of the wearer, in addition to girth measurements, to achieve proper sizing of front and back panels and proper fit of the complete armor. 4.5 This practice can be used to train individuals on proper measurement techniques and to train wearers on proper fitting of body armor.
