1.1本试验方法可用于确定商业厨房中用于在进入排气管之前捕获油脂流出物的部件和系统的油脂颗粒捕获效率。结果可用于选择最适合特定应用的过滤系统。 1.2本试验方法适用于过滤器组件和系统。性能信息是为新的或清洁的过滤器获得的，不包括已使用或加载的过滤器的性能。 1.3过滤器可根据以下方面进行评估（如适用）: 1.3.1压降作为通过过滤器（10.3）的气流的函数，以及 1.3.2按粒径计算的颗粒捕获效率（10.4）。 1.4以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.5 本试验方法可能涉及危险材料、操作和设备。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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 压降结果可以添加到排气系统中其他部件的压降中，以确定排气扇的总压力要求。 颗粒捕捉效率可与烹饪器具的已知颗粒大小排放数据一起使用- 食品组合，以确定过滤器捕获的油脂颗粒的总质量、通过过滤器的油脂颗粒的总质量以及通过过滤器的油脂颗粒的粒度分布。图1显示了示例粒子捕获效率曲线。 图1粒子捕获效率示例曲线

1.1 This test method can be used to determine the grease particle capture efficiency of components and systems used in commercial kitchens to capture grease effluent prior to entering the exhaust duct. The results can be used to select a filter system best suited to a particular application. 1.2 This test method is applicable to filter components and systems. The performance information is obtained for new or clean filters and does not include the performance of used or loaded filters. 1.3 The filter can be evaluated with respect to the following (where applicable): 1.3.1 Pressure drop as a function of airflow through the filter (10.3), and 1.3.2 Particulate capture efficiency by particle size (10.4). 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only. 1.5 This test method 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== The pressure drop results can be added to the pressure drops of other components in an exhaust system to determine the total exhaust fan pressure requirement. The particulate capture efficiency can be used with known particulate size emission data for a cooking appliance-food product combination to determine the total mass of grease particles captured by the filter, the total mass of grease particles that pass through the filter, and the particle size distribution of the grease particles that pass through the filter. Fig. 1 shows an example particle capture efficiency curve. FIG. 1 Particle Capture Efficiency Example Curve
