Abstract
Our country’s CNS “Method of test for air permeability of windows and doorsets” has used about 30 years. We find some items which are not fit for our country at present.
Nowadays the global extreme climate and air pollution are made by people. Let all people have to bear uncomfortable weather and temperature. And the disaster of haze has been enlarged on earth. Let our environment be destroyed. So the CNS standard of test for air permeability of windows and doorsets has to make more suitable adjustments.
Because our national institute laboratory has much experience in the test for air permeability of windows and doorsets. Now we gather these data of the test. After making deep analysis, it should be able to enforce the research of the CNS standard of test for air permeability of windows and doorsets. Therefore, this research will use the following ways to confirm how to offer adjustments for the CNS standard of test for air permeability of windows and doorsets.
1.First, we gather the last abroad test standards of test for air permeability of windows and doorsets, compare to the standards of that in our country.
2.Then we have to analyze the test deta of the test for air permeability of windows and doorsets in our national institute laboratory. We also have to understand and find the problems of the CNS standard of test for air permeability of windows and doorsets..
3.We prefer to use the standards of test for air permeability of windows and doorsets from abroad. Then we have to analyze their differences.
4.We also have to to interview domestic aluminum window’s professional people to get further advices of CNS “Method of test for air permeability of windows and doorsets” . The suggestions can afford Bureau of Standards, Metrology and Inspection, M.O.E.A, R.O.C for adjustments of the CNS standard of test for air permeability of windows and doorsets .
Because we have to reinforce correlative architectural people to recognize the standard of test for air permeability of windows and doorsets, this research will make beneficial application of the CNS standard of test for air permeability of windows and doorsets. The draft of CNS “Method of test for air permeability of windows and doorsets” will be more practical and exact. We can get practical achievements from it. That’s the reason why we offer the following suggestions:
1.We suggest the drawings of CNS11527（2004） “Method of test for air permeability of windows and doorsets” to modify. It will become one test chamber. We must cancel another side’s test chamber.
2.The draft we suggest to add（2）quantity of ventilation / square area of opening parts to be the measure way.
3.The draft we suggest to add（3）quantity of ventilation / the length of opening parts to be the measure way.
