Blower Door Test Procedure
鼓風(fēng)機門(mén)測試程序
Outline 概述
The following test procedures will be required to be undertaken for the new XX Office Building.
要求對XX新建辦公樓做以下測試程序.
A blower door test is meant to measure the air tightness of a building envelope. It to ensure proper quality
of assemblies, connections and finishing.
鼓風(fēng)機門(mén)測試是為了測試整個(gè)樓體的氣密性。是為了確保組裝，連接和*終完工的質(zhì)量。
If the test results are not achieved, then any and all costs associated with engaging another contractor will
be at the cost of the C700 General Works Contractor.
如果測試結果未達標，所有相關(guān)的費用都將由C700 總承包商承擔。
Test Specification
測試詳述
There are several indexes that can be used and we will specify the main one, which is called n50 (the air
changes per hour at 50Pa pressure difference between indoor and outdoor, building indoor being
depressurized or under negative pressure).
有幾個(gè)可供使用的指數，在此我們詳細說(shuō)明主要的一個(gè)叫做n50(室內和室外空氣在50 帕壓力下每小時(shí)的變
化，室內被減壓或在負壓以下)
In order to reach the type of infiltration control we want, the n50 index should not exceed 0.95ach as a
result of the blower door test. This is not to be taken for granted and can be achieved with only a proper
quality of assemblies, connections and finishing.
為了達到我們期望的滲透控制，鼓風(fēng)機門(mén)測試結果n50 指數不能超過(guò)0.95ach。這不是想當然的是需通過(guò)組
裝，連接和*終完工并達到一定質(zhì)量而獲得的。
Another index usually used is i4, expressed in m3/h/m2 of envelope under 4Pa pressure difference
between indoor and outdoor. The i4 value that would correspond to the n50 specified above is
0.37m3/h/m2.
另一個(gè)常被用到的指數是i4，向樓體內擠低于4 帕的壓力時(shí)室內和室外的區別。I4 指數應與以上所述n50
指數相符，應為0.37m3/h/m2
As a way to do the correspondence, a similarly shaped building aiming at a PassivHaus standard for air
tightness, recognized as the most stringent, would require a i4 of 0.23.
作為一種對應方法，一棟類(lèi)似形狀建筑的氣密性達到PassivHaus 標準，被認為是***的，要求i4 指數
為0.23.
Air Tightness Test Failure
空氣氣密性測試失敗
Velux may elect to engage a third party testing company. In the event the test results indicate that the
building has not achieved the required air tightness, not only will the cost of this and any future tests, all
costs of the rectification works shall be borne solely by the C700 General Works Contractor.

威盧克斯可以選擇第三方作為測試公司。當測試結果顯示樓體氣密性未達到要求，本次測試和以
后的測試以及整改工作等相關(guān)費用都將由C700 總承包商承擔。
