Typically, the air velocity is within + 20%.风速的均匀度同时被检测。典型均匀度为+ 20%,Standard defines a leak is a hole which would produce a local penetration of 0.01% with an upstream concentration of 100%.按标准，当上游浓度100%时，下游浓度检测到0.01%穿透则视为泄漏,Leak Test 检漏测试,Filter Testing 过滤器检测,Leak Repair 泄漏修补,Filter Leaks 0.01% are patched. 0.01%的泄漏点可以修补Filter media is patched with medium or adhesive. 采用联胶或介质修补For any one leak - maximum area of patch is 2 in2 (13cm2). 任何一个泄漏点不可超过2 in2For the filter, the patching is limited to a maximum of 1% of the face area (IE-RP-CC001-3).根据IE-RP-CC001-3标准，过滤器泄漏点的修补面积不可超过过滤器面积的1%,Leak Test Report,Filter Testing Report 过滤器检测报告,Leak Found Report,Filter Testing Report 过滤器检测报告,Defect Map,Filter Testing Report 过滤器检测报告,Air Velocity Test Report,Filter Testing Report 过滤器检测报告,Fan Filter Unit TestingFFU测试,FFU Testing Chamber FFU测试台,The FFU Testing Chamber is specially designed to maintain an environment with room temperature of 24oC and ambient noise level below 35dBA for measuring : 特别设计的FFU测试台可在室温24oC 及背景低于35dBA的无响室内测量： air velocity 风速Probe Velocity Anemometer 风速计 noise level 噪音 Sound Level Meter 噪音计 external static pressure 机外静压 Air Flow Micromanometer 压力表 filter pressure 过滤器压损 Air Flow Micromanometer 压力表 electrical characteristics 电力参数Power Meter 功率表,Schematic Diagram of FFU Testing Chamber FFU测试台示意图,FFU Testing Chamber FFU测试台,Air Velocity Test 风速测量,The Probe Velocity Meter is used to measure the average air velocity at 8 points, 300mm below the FFU. For accurate readings, data is only recorded after the probe is stationary for at least 5 seconds. 风速在FFU过滤器出风面下300mm处测量8个点的平均风速。为得到准确地数值每点测量时测点需保持最少5秒时间。,
