A3.1.1. Test Chamber 实验箱

A.3.1.1.1. Structure and Shape 构造和外形

When Clean Air Delivery Rate (CADR) is more than 0.1 m3/min and less than 1.6 m3/min, it shall be tested in a chamber of 8.0±0.5 m3 and when it is more than 1.6 m3/min and less than 16.0 m7min, it shall be tested in a chamber of 29.5±1 m3, when CADR more than 16.0 mVmin, it shall be tested in a chamber of 50.0±l m3. The test chamber, as shown in Picture Al.4, shall be of a rectangular parallelepiped shape (regular hexahedron is possible).
The inside of the test chamber shall be structured with anti-static panels. The test chamber shall be equipped with high-performance (above HEPA) filter that can supply air that meets background concentration (4.1.1.2), an inlet connected with a control valve, and an outlet connected with a damper thatdischarges excessive indoor air automatically.

当干净氛围运送率(CADR)大于0.1 m3/min小于1.6 m3/min时,应在8.0±0.5 m3的实验箱,当大于1.6 m3/min且小于16.0 m7 min时,应在室29.5±1 m3,当cadr大于16.0 mvmin时,应在50.0±l m3的室中停止实验。测试如图A1.4所示,腔体应为矩形平行六面体(可为正六面体)。试验室内部应装备防静电面板。试验室应装备高机能(HEPA以上)过滤器,可供给满意布景浓度(4.1.1.2)的氛围,入口与掌握阀毗连,出口与主动排挤过量室内空气的阻尼器毗连。

A.3.1.1.2. Concentration of Background Particles

Concentration of background particles inside the test chamber: It shall be below 3><105 Count/m3 per particle of 0.3

布景粒子浓度

实验室内布景颗粒浓度:每粒0.3粒应低于3><105计数/m3。

A・3・l・l・3・ Air Tightness

Air tightness of the test chamber shall meet more than 80% of initial particle concentration per particle of 0.3 “m
after 20 minutes. Here, measurement procedure shall in compliance with 4.2.2.

气密性

试验室的气密性应满意每粒0.3“m颗粒初始颗粒浓度的80%以上。20分钟后。此处,丈量法式应契合4.2.2的要求。

A.3.1.1.4. Concentration of Test Particles

In the test chamber, a particle generator and a vortexer shall be installed in a way that test particles can have uniform
distribution of concentration spatially in a short time period. When measuring, the initial concentration of particles
in the test chamber shall be 1 〜3 x 108 count/m3.

实验颗粒浓度

在试验室中,应以实验颗粒平均的方法安装颗粒发生器和涡流器。短时间内浓度的空间散布。丈量时,颗粒的初始浓度试验室内应为1〜3 x 108计数/m3。

A・3・l・l・5・ Number of Test Specimen试样数目

The number of test specimens shall follow Table Al.l by the rated air volume of test specimen.按照试样的额定空宇量,试样数目应契合表al.l的要求。

A.3.1.1.6. Installation Position of Test Specimen 试样安装位置

Test specimen shall be installed where is specified in the instruction manual of a product. In case it is not specified
in the instruction manual of a product, the followings are applied. 试样应安装在产品说明书划定的位置。产物利用说明书未作划定的,按以下划定施行。

  • A product (test specimen) of desktop type and desktop/wall mounting shall be installed near wall and on a desk
    top 70cm above from the floor.
  • Floor type shall be installed on the floor near a wall side.
  • For wall mounting-exclusive type, the bottom of the product shall be installed 180cm above from the floor.
  • In case of installation of 2 test specimens, the center of the test specimens* chambers shall be symmetric with each
    other.
