烹调抽油烟机性能测试方法

[中文适用范围]： 本文件适用于安装在家庭厨房中、带有风扇并用于回流模式或排放模式的烹饪油烟 extractor。它也可用于风扇与 appliances 分开安装但由 appliance 控制（在技术文档如铭牌数据和安装说明中定义）的烹饪油烟 extractor。本文件还涉及安装在烹饪 appliance 旁边、后面或下方的下拉式系统。本文件定义了这些 appliance 的主要性能特征（用户感兴趣的部分），并规定了测量这些特征的方法。本文件不规定性能的分类或排名。注：本文件不涉及符合 IEC 60335-1 和 IEC 60335-2-31 的安全要求。 [外文原描述]： IEC 61591:2019 applies to cooking fume extractors incorporating a fan for the recirculation or extraction mode situated in a household kitchen. It can also be used for cooking fume extractors where the fan is mounted separately from the appliance, but controlled by the appliance when the fan is defined in the technical documentation (e.g. name plate data) and instructions for installation. This document deals also with down-draft systems arranged beside, behind or under the cooking appliance. This document defines the main performance characteristics of these appliances, which are of interest to the user, and specifies methods for measuring these characteristics. This document does not specify a classification or ranking for performance. This document does not deal with safety requirements that are in accordance with IEC 60335-1 and IEC 60335-2-31. This second edition cancels and replaces the first edition published in 1997, Amendment 1:2005 and Amendment 2:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) new subclause about instruments and measurements (see 6.6); b) new procedure for measuring the fluid dynamic efficiency (FDE), which follows the CENELEC proposal in principle; c) revised procedure for determining the odour reduction for cooking fume extractors in recirculation mode (see Clause 12); d) modification to the measurement of the effectiveness of the lighting system (see Clause 11); e) clearer procedure to measure the grease absorption (see Clause 13);
