1、液体泵和泵组CE认证指令

MD机械指令：2006/42/EC

2、液体泵和泵组CE认证标准：

EN ISO 12100：2010 机械安全 - 用于设计的一般准则-风险评估及风险降低

EN 60204-1：2018机械安全.机械电气设备.第1部分：一般要求

EN ISO 20361:2009 Liquid pumps and pump units - Noise test code - Grades 2 and 3 of accuracy 液体泵和泵组.噪声试验规范.精度等级2和3

3、EN ISO 20361:2009适用范围：

This International Standard specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.

Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for

⎯ declaring the noise emission values,

⎯ purpose of noise control at source at the design stage.

NOTE 1 The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market.

The use of this International Standard ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to this International Standard are engineering methods (grade 2) and survey methods (grade 3).

This International Standard does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.

NOTE 2 This International Standard is intended to complement EN 809, Pumps and pump units for liquids — Common safety requirements.

本国际标准规定了在标准化条件下高效进行液体泵或泵组空气噪声排放的测定、声明和验证所需的所有信息（见4.1）。它规定了噪声测量方法以及测试中应使用的操作和安装条件。

噪声发射特性包括指定位置的发射声压级和声功率级。确定这些数量是必要的

—声明噪声排放值，

—设计阶段源头噪声控制的目的。

注1：为了比较市场上液体泵发出的噪声，也需要确定这些数量。

使用本国际标准可确保在所用基本空气噪声测量方法的精度等级所确定的规定范围内，空气噪声排放特性的测定具有可重复性。根据本国际标准，噪声测量方法为工程方法（2级）和测量方法（3级）。

本国际标准不涉及液体泵产生的结构传播声音和液体传播噪声的特征。

注2：本国际标准旨在补充EN 809《液体用泵和泵装置——通用安全要求》。
