Health and safety in welding and allied processes — Equipment for capture and separation of welding fume — Part 4: Determination of the minimum air volume flow rate of capture devices 焊接和相关工艺中的健康和安全.焊接烟尘捕集和分离设备.第4部分:捕集装置最小空气体积流量的测定

发布日期： 2020-02-21

                本文件规定了两种确定最小风量的方法。一种方法专门用于捕捉器罩、喷嘴和狭缝喷嘴，狭缝长度与软管直径之比为8:1或更小。另一种方法专门用于枪上提取设备。
这些方法不适用于下吸式工作台。

This document specifies two methods for establishing the minimum air volume flow rate. One method is dedicated for use with captor hoods, nozzles and slot nozzles with a ratio of slot length to hose diameter of 8:1 or less. The other method is dedicated for use with on-gun extraction devices.
These methods are not applicable to down draught tables.
