1.1 本规范涵盖了小型无人驾驶飞机（sUA）/小型无人驾驶飞机系统（sUAS）可展开降落伞的设计和制造要求。本规范定义了可安装、可展开降落伞回收系统（PRS）的设计、制造和测试要求，这些系统被设计成集成到sUA中，以在sUA无法维持正常、稳定的安全飞行时减少系统的冲击能量。 1.1.1 遵守本规范旨在支持申请人获得民航局（CAA）的许可，在人员上空驾驶sUA。 1.1.2 不包括第节所有最低要求的PRS 5 和部分 6 不应称为满足本规范。如果PRS已按照规范F3322成功测试-18或规范F3322-22与第三方测试机构（TPTA），或两者兼而有之，集成商可以使用先前的结果来支持测试矩阵的完成，并声明规范F3322-24是通过认证数据包中先前提及的测试的先前延续的延续而完成的。集成商应公开规范F3322-24 TPTA报告。公开的TPTA报告应与提供给任何监管机构的报告相同，不包含修改或修订。 1.2 本规范适用于可部署PRS的设计、构造和测试，这些PRS可能被纳入sUA的系统或结构中，或两者，以技术标准订单（TSO）、飞行证书、飞行豁免、飞行许可或其他类似文件的形式寻求CAA批准。本文档是在ASTM F38库的更广泛背景下有目的地设计的。尽管此处介绍的内容的原始原始材料旨在作为独立文件发挥作用，但F38委员会有意识地删除了任何冗余信息，以支持采用参考性的“单一事实来源”方法。因此，在应用本规范时，必须考虑并整合所有相关的ASTM F38标准，以确保其全面和准确的实施。 1.3 当打算利用本文件中提供的信息作为操作批准、设计批准或两者的合规手段时，就其可接受的用途和应用咨询相应的监督机构（例如CAA）至关重要。要了解哪些监管机构已接受本标准（全部或部分）作为遵守其监管要求（以下简称“规则”）的可接受手段，请参阅ASTM F38网页(www.ASTM.org/COMMITTEE/F38.htm)。 1.4 单位- 以SI单位表示的值将被视为标准值。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.6 本国际标准是根据th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的标准化原则制定的e世界贸易组织技术性贸易壁垒委员会。

1.1 This specification covers the design and manufacture requirements for deployable parachutes of small Unmanned Aircraft (sUA)/small Unmanned Aircraft Systems (sUAS). This specification defines the design, fabrication, and test requirements of installable, deployable Parachute Recovery Systems (PRS) that are designed to be integrated into an sUA to lessen the impact energy of the system should the sUA fail to sustain normal, stable safe flight. 1.1.1 Compliance with this specification is intended to support an Applicant in obtaining permission from a Civil Aviation Authority (CAA) to fly an sUA over people. 1.1.2 PRS that do not include all the minimum requirements of Section 5 and Section 6 of this specification shall not be referred to as meeting this specification. If a PRS has been tested successfully to Specification F3322-18 or Specification F3322-22 with a Third Party Testing Agency (TPTA), or both, the Integrator may use the previous results to support completion of the testing matrix and declare that Specification F3322-24 was accomplished through a continuation from the previous continuation from the previous aforementioned testing in the certification data package. The Integrator shall make the Specification F3322-24 TPTA report publicly available. The publicly available TPTA report shall be the same as/identical to the one provided to any regulator and not contain modifications or redactions. 1.2 This specification is applicable to the design, construction, and test of deployable PRS that may be incorporated into the system or structure, or both, of sUA seeking CAA approval in the form of Technical Standard Orders (TSO), flight certificates, flight waivers, flight permits, or other like documentation. This document has been purposefully designed within the broader context of the ASTM F38 library. Although the original source materials for the content presented here were intended to function as standalone documents, the F38 Committee has consciously removed any redundant information in favor of adopting a referential "single-source-of-truth" approach. Consequently, when applying this specification, it is essential to consider and integrate all relevant ASTM F38 standards to ensure its comprehensive and accurate implementation. 1.3 When intending to utilize the information provided in this document as a Means of Compliance for operational approval, design approval, or both, it is crucial to consult with the respective oversight authority (for example, CAA) regarding its acceptable use and application. To find out which oversight authorities have accepted this standard (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter "the Rules"), please refer to the ASTM F38 webpage (www.ASTM.org/COMMITTEE/F38.htm). 1.4 Units— The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.5 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.
