一、法规概述
序号 | 标准 | 国家 | 描述 |
1 | BS EN 12237:2003 | EU | Ventilation for buildings—Ductwork—Strength and leakage of circular sheet metal ducts. |
2 | BS EN 1507:2006 | EU | Ventilation for buildings—Sheet metal air ducts with rectangular section—Requirements for strength and leakage. |
3 | DW/143 | EU | HVAC—A practical guide to Ductwork leakage testing. |
4 | Eurovent 2/2 | EU | Air leakage rate in sheet metal air distribution systems. |
二、法规详情
1. EU Standards EN12237
2. EU Standards EN1507

3. EU Standards Dw/143

4. EU Standards Eurovent 2/2

三、细则分析
1)判定
实际测试泄漏率<法规计算下的最大值Air leakage limit (fmax) 则被测管道合格2)注意事项
EU Standards - Dw/143单位不同,l/s/m2,实际计算需要区分,换算。GTI 管道漏风量测试机型号DALT6900,DALT6910仪器内置以上标准,无需计算,可以直接输出判定结果,操作简单方便!
