HEPA／ULPA过滤器的性能是与其测试方法
相关联的，随测试方法的不同而有不同表示。现
把我国及国际上有代表性的规定或标准简介如下：
1．1美国有关规定(IEST．RP—CC一001)
(1)它对HEPA／ULPA过滤器按性能分类及
其测试方法要求简要综合见表1。
哀I 性能类型及测试方法要求(皿 r_ltI，一CC0o1)
(2)HEPA／UU，A过滤器透过率测试方法按
Mil—std一282标准(美国军标)，检测仪器采用光度
计，测试尘源需采用单分散(冷发)DOP，粒径为
0．3p,m，此方法传统称DOP法，对B、E类过滤器规定
以额定风量及20％额定风量进行测试。
(3)ULPA过滤器采用IEST-RP-CC007的方法
进行效率测试，检测仪器为粒子计数器，在效率测
试前先需测定过滤介质的最易透过粒径(MPPS，
Most Penetrating Particle Size)，对ULPA过滤器一
般在0．1—0．2 m范围内；
(4)HEPA／ULPA过滤器的检漏按IEsT—RP—
CC034规定，综合有关要求· 55·
表2 检漏要求
注：标准泄漏透过率，指取样量为28．3L／rain时下风侧浓度与上风侧浓度之比，超过此值即为漏。
1·2欧洲有关规定(EN1822) 行
， 把过去欧洲各国混乱的各类及其测试方法都
(1)ENl822标准于1998年颁布，现在欧洲执 统一于此
。有关类型及其性能要求见表3。
表3 类型及其性能要求(EN1822)
注：HEPA 过滤为H13，H14，UI5~U17为ULPA过滤器
(2)此测试系统的检测仪器为粒子计数器，
尘源气溶胶亦是开放的，测试前先测定过滤介质的
MPPS，皆与美国IEsT—RP—CC007的方法类同。不
同的是测试采用扫描，即过滤器上风侧用可移动的
喷管供给测试用气溶胶，在下风侧用可移动的探头
进行扫苗采样，以每一扫描测试到的浓度与上风侧
测得浓度的对比，便可得|出局部透过率，然后统计
整理，得出(综合)透过率及(综合)效率。
(3)其检漏测试，在扫描测试局部透过率便
已解决，只要被测过滤器的局部透过率不超过规
定的局部值便为合格。
1．3 我国现行规定“高效空气过滤器”分类及测
试要求
我国标准(GB13554-92)规定高效过滤器的性
能分类及测试要求综合见表4。
表4 性能类型及测试方法要求(GB13554-92)
(1)效率测试：
B、C类过滤器都各以额定风量及20％额定风 3．5×l0’PC／m3的大气尘或其他气溶胶，并以额定
量测试。D类属ULPA”~滤器，用粒子计数器进行 风量及2 额定风量进行测试；但尚未有测试方法
测试，粒径为0．1 Il ITI，尘源用原始浓度为3．5xl&~ 的具体标准及规定。
· 56 ·
(2)检漏
C类过滤器，尘源采用多分散DOP，其上风侧
浓渡应达100 it g／L以上，下风侧浓度达到上风侧
的1O一时即为漏；D类过滤器，检漏仪器及尘源同
效率测试，任一点的透过率超过额定风量下的透
过率即为漏；采样流率>lL／min时，扫描速度应<
5cm／s，采样流率≤1Lmin时，扫描速度应<2cm／
s。但都尚无其他具体标准及规定。
2 问题及讨论
对当前有代表性的HEPA／ULPA过滤器性能
测试方法进行对比分析，提出以下几个值得注意
及讨论的问题：
2．1 这类过滤器性能的反映随其测试方法而
异，各方法间难以定量对比
这主要由于：测试仪器及相适应的尘源气溶
胶的不同以及相应会引起误差的有关参数控制措
施考虑的不同所引起，如：
(1)检测仪器。现行的基本为分为两类，一
是粒子计数器，它的测试值反映的是气流中粒子
个数的浓度(PC／L)并规定粒径范围，其灵敏度
较高，对所有尘源气溶胶选择余地较大；二是光
度计，它反映的是粒子质量浓度(mg／L)，因此
作效率测试时，只能用按要求粒径的单分散气溶
胶，两种仪器测试结果难以定量对比。即使同一
类粒子计算数器：采用单分散DOP或多分散DOP
时虽都以同一粒径进行检测，其结果亦不一样，
单分散DOP的透过率大， (这是因为单分散DOP
的粒径分布范围很窄，在规定粒径下的浓度很
高)，其间至今尚无换算关系可循。
(2)测量本身的要求随不同测试方法而异，
其对会引起测试误差的参数的控制，诸如尘源气
溶胶在测试过程中的稳定性及均匀性、风量及风
速的稳定性及均匀性(这一点对扫描测试更为重
要)、扫描速度的控制、气溶胶可能带电的中和、
上下侧试管路的相差系数以及温湿度等的纠正等，
都往往是不一样的，都会引起测试结果的不同。
在安装现场再测试过滤器效率，不可能有生
产厂的测试条件，其结果便很说明问题，所以主
要是要求制造厂保证性能。
2．2 粒子计数器比光度计灵敏度高
对UL-PA过滤器的性能测试，后者已不适应
要求，已不能采用。钠盐法的检测仪器，亦是一
种光度计(火焰光度计)， 钠盐粒径范围为
0．02itm～2it rn，其质量平均粒径约为0．5itm～
0．6it rn，钠离子对半导体工业的产品生产有害，
因此已不适应当前对HEPA过滤器性能的测试要
求，国外都已淘汰。
另外粒子计数器较之光度计在尘源气溶胶的
选择余地亦大，因此它作为HEPA过滤器的性能测
试亦终是趋势。
2．3 测试用尘源气溶胶
人工气溶胶DOP已有近40年历史，一段时间
以来， 因被怀疑对人有致癌作用，现常以DOS
(Dioctylsebaeate癸二酸二辛脂)亦称DEHS[di
(2-ethylexy1) sebacate] 及PAO (polya卜
phaolefin聚Q烯烃)等代替，但这些物质都被认
为对半导体及磁盘驱动器等产品有害，现国外常
多以SPL(聚苯乙烯乳胶球)替代，用于粒子计数
器为检测仪器的测方法中。
大气尘由于其浓度随地点及时间等变化，有
时较大，且其浓度亦底，因此国外不认可作为
HEPA及ULPA过滤器的性能测试之用，因为测试
结果的准确性不足。
2．4 EN一1 822的MPl，S法
其特点是， (综合)效率由扫描测试局部效
率后得出， 同时解决了检漏问题，但系统及操作
较复杂。
EN一1822的MPPS法，对HEPA／UU’A过滤器
都先测定过滤介质的MPPS，美国对ULPA过滤器
效率的测定亦是先测定过滤介质的MPPS。过滤器
的MPPS除介质结构(纤维直径及其分布)外，亦
与滤速及尘源气溶胶组成有关，对HEPA／Um
过滤器一般都在0．1"43．3ll m间，对单一的确定
MPPS亦有认为不必要，对工程应用中实际意义不
大，因此在商业上，HEPA过滤器现多用0．3 ll m粒
径测试，对ULPA过滤器现常用0．12 ll m。
2．5 过滤器透过率测试
美国在“HEPA过滤器”的性能测试中，规规定对B、
E类过滤器用两种流量(额定流量及2O％额定流
量)进行透过率测试，实际上主要是为了检漏。
因为20％额定流量时，若有针孔存在则通过针孔漏
· 57 ·
至下侧的气溶胶泄漏率约为额定时的25倍，所以，
对额定风量时未检到的泄漏，易在20~,6额定流量时
被发现。美国对规定以分光光度计或粒子计数器
扫描检漏的过滤器，一般都不进行20~,6额定风量的
透过率测试。我国目前对C类过滤器(已规定用光
度计扫描检漏)及D类(HEPA过滤器，用粒子计
数器扫描检漏)，还要求用两种流量进行透过率测
试，似无必要。
2．6 HEPA Um 过滤器检漏，需要注意以
下问题
(1)一般宜用与测试效率的同一类仪器检漏，
因为规定的允许泄漏透过率，不同的仪器无规定
的对比关系可循，需用户与制造厂双方商定。
(2)检漏时规定的允许泄漏透过率应比效率
测试时规定的透过率为宽，因为扫描检漏时某一
点穿透率(即局部透过率)，其测量误差往往较
大；EN-1822规定超过局部透过率便为漏，一般
约为(综合)透过率的5倍，对UI7过滤器为1O倍；
美国对“ULPA过滤器”亦规定为达到透过率的5倍为
漏。对现场检漏，则比制造厂检漏要求要放宽些，
因为现场检测系统及操作都不如制造厂，误差亦
会大，EN-1822对现场检漏认为超过局部穿透率
时，泄漏可能性大，达到1O倍时为漏。美国规定
(上接第54页)
(4)冷却塔：降低冷却塔风机的转速，可以有效
地降低冷却塔的噪声，优化冷却塔水流分配及为冷
却塔加装适当的隔声板也可以降低噪声的产生。
(5)空分装置及空压机；采用具有隔声罩的空压
机，并在空分及压缩空气排气管道上加设消声器，
降低排气噪声。
(6)柴油发电机：为柴油发电机装设隔声罩，并
在吸排气管道上装设消间器；或对柴油机房采取必
要的降噪、隔声措施等。
(7)泵：在泵体基础上加装减振基座，泵的进出
口管道上均设置泵用软管接头，减少泵运行时对建
筑及管道的影响。
(8)建筑噪声：对于噪声较严重的空调机房、冷
· 58 ·
对要求高的ULPA过滤器，现场检漏亦为1O倍。
美国对HEPA过滤器的检漏，虽然允许标准泄
漏透过率与透过率相同，但由于效率测试及检漏
都是用光度计，前者的尘源气溶胶为0．3 Il 11’1单分
散DOP；后者多分散DOP，其粒子平均粒径约为
O．7 Il m，这就存在着差别，后者的要求宽于前者。
我国对过滤器的检漏规定超过透过率即为漏，
由于对过滤器检漏，尚未有具体的标准，如对各
种影响结果的其他参数作控制等，因此，亦难与
国外的泄漏透过率作对比，但若按检漏系统及操
作控制合乎精度的话，则规定的泄漏透过率就严
了。

冻站、空压站等产生噪声设备集中的房间，在建筑
围护结构或建筑空间采取隔声、吸声等降噪声措
施，减少对周围环境的噪声传播。为确保操作人员
的安静环境，可设隔声值班室。
3．4 管道及阀门
(1)为管道架设可靠的固定支架及弹簧减振
支架，可有效地降低流体输送时产生的振动噪声。
(2)为自动控制阀等加装牢固的固定支架，避
免阀门在动作时产生不必要的噪声。
总之，采用上述手段，还应与技术经济性比较
结合起来，通过技术经济性的比较，采用行之有效

经济、环保的生产环境中。
