A theoretical study to compare the sensitivity standards for smoke detectors [8] was completed.The study compared four standards:Draft ISO/DIS 12239 [7],BS 5446:Part 1 [1],UL 217 [5] and the proposed revision of BS 5446:Part 1 [4] to decide whether the proposed revision of BS 5446 could be accepted in place of the existing BS 5446.The study also reviewed the similarities between the fire test specifications for the existing and revised BS 5446 and also the existing European standard for commercial detectors (EN 54).The study concluded that BS 5445 and BS 5446 (revised) had effectively the same requirements on fire sensitivity.Furthermore,it appeared that BS 5446 (original) required a greater fire sensitivity when compared to BS 5446 (revised).It further concluded that BS 5446 (original) and BS 5446 (revised) could not be directly compared as they used different sets of fire tests and different pass/fail parameters.
The fire tests were selected so as to closely match the fire sensitivity specified in BS 5445 :Part 9 :1984 [2] (TF 2-5) or the draft ISO standard [7] (TF 7).In addition,two non-standard tests were conducted as representative of realistic fire scenarios that occur in dwellings (Table 1).The fire tests that matched the sensitivity tests are referred to as the ‘standard’ tests and the two realistic fires are referred to as the ‘ad-hoc’ tests.The downstairs dining room (at the rear) and the upstairs bathroom were both sealed.The doors to the other two first floor bedrooms were kept closed for all of the tests.The kitchen door was closed for all tests apart from Test 10.The fire tests were terminated once all detectors had gone into alarm or when it was considered that no more detectors would raise an alarm.

理论研究标准比较敏感的烟雾探测器[8]都完成了.这项研究比较了四种标准:草稿ISO / DIS 12239[7],BS 5446:第一部分[1][5],UL 217建议和修改本科以上5446:第一部分[4]来决定该修改5446可以接受专业的本科以上5446存在的地方.这项研究还回顾了火测试规格相似之处使用现有的和修订5446并获得现有的欧洲标准为商业探测器(EN第54条).研究认为,BS,5445 5446(修订)获得有效放火烧了同样的需求敏感.此外,现在看来,本科以上5446(原件)需要一个强大的火灵敏度相比5446 BS(修订).进一步得出结论,本科以上5446(原件)、BS(修订)5446不能直接比较,他们用不同的火灾试验和不同的通过/不通过参数.
选择的火灾试验,密切配合专业的火中规定5445敏感性组分:9:1984年[2](技术),或者是2 ISO标准草案[7]技术(7).此外,两个非标准的试验是为代表的真实的火的情景,发生在住处(表1).匹配的火灾试验的灵敏度测试被称为“标准”的测试和两个现实火灾都被称为“特别的测试.楼下的食堂(在尾部)和楼上的浴室都密封.门到另外两个一楼卧室是保持关闭了所有的测试.厨房的门关闭了所有的测试除了测试10.终止的火灾试验一旦所有探测器进入了报警或当认为探测器会提高不再发出警报.
