1.1 这些测试方法旨在评估市场雨伞（MU），以根据风安全性和耐久性确定MU在使用环境中的适用性。 1.1.1 程序A是一种安全场景，旨在测试MU在风洞产生的均匀风力下的结构强度。 1.1.2 程序B是一种风耐久性场景，旨在确定MU在大风天气环境中持续执行的能力。 1.1.3 然后使用波弗特量表对MU的性能进行评级，如所示 附件A1 ，以传达MU的安全性和耐久性性能。 1.2 这些测试方法适用于大多数设计用于家庭环境的MU，如游泳池或天井区域；休闲区，如海滩、游泳池或网球场； 以及商业环境，如主题公园、水上公园、度假池、酒店、餐厅、咖啡馆和其他商业环境。 1.3 以英寸-磅为单位的数值应视为标准值。括号中的值仅供参考。 1.4 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。 1.5 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====== 5.1 这些测试方法建立了用于评估MUs性能、风安全性和耐久性特征的标准程序。 5.2 这些测试方法适用于最终用户和制造商评估MUs和基座安装组件的性能特性。 5.2.1 最终用户可以使用这些测试方法来确定MUs和基础组件满足其特定应用和使用条件的程度。 5.2.2 MUs和基座安装组件的制造商可以使用这些测试方法来确定现有或拟议设计中的风性能特征。 5.3 程序A是通过使MU承受风洞产生的均匀风来评估MU结构完整性（杆、框架、雨篷和底座组件）。 程序B是通过将MU置于风洞产生的均匀风中一段固定时间来评估MU和基础部件的耐久性。每个程序用于使用波弗特等级对MU和基础支柱性能进行评级，以便用户能够将测试中确定的风速安全性和耐久性与MU使用区域的视觉和主观观察相关联。 5.4 由于用于电杆、框架、雨篷、通风口和轮毂的MU材料和设计以及基准重量、形状和保持机构的差异，在一种类型的MU和基座组件上使用这些测试方法的结果与在不同MU上的其他测试结果不可比。 5.5 这些测试方法不旨在评估实际使用环境中因磨损而产生的清洁或其他天气压力。 5.6 MU和基础部件的最终用户和制造商应将这些测试方法视为评估MU和基础部件风安全性和耐久性特性的最低程序，因为根据ASCE/SEI 7-10风洞程序，风洞程序被视为产生任何方法中最准确的风压。这些测试方法的用户可能希望考虑与其应用直接相关的其他测试和程序，例如有限元分析软件。 5.7 MU的每个买家都应该制定自己的标准来评估可接受的安全性和耐用性性能。

1.1 These test methods are intended for evaluating market umbrellas (MUs) to determine the suitability of the MU in a use environment on the basis of wind safety and durability. 1.1.1 Procedure A is a safety scenario intended to test the structural strength of the MU to a uniform wind force generated by a wind tunnel. 1.1.2 Procedure B is a wind durability scenario intended to determine the ability of the MU to perform in a high wind weather environment for a sustained period. 1.1.3 The performance of the MU is then rated using the Beaufort Scale, as shown in Annex A1 , to communicate the safety and durability performance of the MU. 1.2 These test methods apply to most MUs designed for use in-home setting, such as pool or patio areas; recreation areas, such as the beach, pool, or tennis courts; and business settings, such as theme parks, water parks, resort pools, hotels, restaurants, cafés, and other business settings. 1.3 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are given for information only. 1.4 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. 1.5 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 ====== 5.1 These test methods establish standard procedures designed for evaluating the performance wind safety and durability characteristics of MUs. 5.2 These test methods are suitable for both end users and manufacturers to evaluate performance characteristics of MUs and base mounting components. 5.2.1 End users may use these test methods to determine how well MUs and base components meet their particular application and conditions of use. 5.2.2 Manufacturers of MUs and base mounting components may use these test methods to determine the wind performance characteristics in existing or proposed designs. 5.3 Procedure A is an evaluation of MU structural integrity (pole, frame, canopy, and base components) by subjecting the MU to a uniform wind generated by a wind tunnel. Procedure B is an evaluation of MU and base component durability by subjecting the MU to a uniform wind generated by a wind tunnel for a fixed period of time. Each procedure is used to rate MU and base stanchion performance using the Beaufort Scale for users to be able to correlate the wind speed safety and durability determined in the testing to visual and subjective observation of the area of uses of the MU. 5.4 Results from use of these test methods on one type of MU and base components are not comparable to other test results on a different MU due to differences in MU materials and designs used for poles, frames, canopies, vents, and hubs as well as base weights, shapes, and holding mechanisms. 5.5 These test methods are not intended to assess cleaning or other weather stress resulting from wear and tear in an actual use environment. 5.6 End users and manufacturers of MU and base components should consider these test methods to be minimum procedures for evaluating MU and base component wind safety and durability characteristics as a wind tunnel procedure is considered to produce the most accurate wind pressures of any method according to ASCE/SEI 7-10 Wind Tunnel Procedure. Users of these test methods may wish to consider additional tests and procedures that relate directly to their application such as finite element analysis software. 5.7 Each buyer of a MU should establish its own criteria for assessing acceptable safety and durability performance.
