1.1 本试验方法涵盖了确定商用和家用立式、罐式、棒式、手持式、多功能和组合式真空吸尘器空气性能特征的程序，这些吸尘器具有连接软管和包含一系列通用电机的规定。该测试方法可应用于地毯清洁操作模式。 1.2 这些测试和计算包括在标准操作条件下确定吸力、气流、空气功率、最大空气功率和输入功率（见 附注1 ). 安装在增压测试上的喷嘴是一种理想的空气性能测量方法，并不代表地毯或地板清洁过程中的实际空气性能。 注1: 有关空气性能特征的更多信息，请参阅参考文献 ( 1. 6. ) . 2. 1.3 本标准采用英尺-磅-英寸单位制。括号中的值仅供参考。 1.4 本标准可能涉及危险材料、操作和设备。 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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，并确定监管限制的适用性。 具体的预防声明见 附注2 . 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 测试结果允许比较在本测试方法条件下测试时可用于清洁任务的最大潜在空气功率。 由于使用的各种工具和被清洁的表面的影响，测试结果没有表明清洁过程中存在的实际空气功率。在喷嘴对增压室空气性能测试期间，刷辊未加载，这种情况并不代表刷辊与地毯或其他被清洁的表面接触。

1.1 This test method covers procedures for determining air performance characteristics of commercial and household upright, canister, stick, hand-held, utility, and combination-type vacuum cleaners having provisions for attaching a hose and incorporating a series universal motor. This test method can be applied to the carpet cleaning mode of operation. 1.2 These tests and calculations include determination of suction, airflow, air power, maximum air power, and input power under standard operating conditions (see Note 1 ). The nozzle mounted on plenum testing is an ideal air performance measurement and is not intended to represent the actual air performance during carpet or floor cleaning. Note 1: For more information on air performance characteristics, see Refs ( 1- 6 ) . 2 1.3 The foot-pound-inch system of units is used in this standard. The values in parentheses are given for information only. 1.4 This standard may involve hazardous materials, operations, and equipment. 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. A specific precautionary statement is given in Note 2 . 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 ====== 4.1 The test results allow the comparison of the maximum potential air power available for cleaning tasks when tested under the conditions of this test method. The test results do not indicate the actual air power present during the cleaning process due to the effects of the various tools in use and surfaces being cleaned. During the nozzle on plenum chamber air performance testing, the brushroll is unloaded and this condition is not representative of the brushroll being in contact with carpet or other surfaces being cleaned.
