BSI对有关部门关于烟雾报警器的论文做出回应

BS EN 14604是政府、监管机构和行业内多年来一直用于烟雾报警装置的最佳规程，是一项成熟且受国际认可的标准。

该项标准涉及市场上最常见的两种烟雾报警器：光电感烟式和离子感烟式，并且明确认识到报警器的反应，会随火灾试验情况不同而有所差异。有关部门的最新研究显示，他们试图在四种不同的测试场景下比较这两种不同类型的报警器的反应。有关部门的论文非常清晰地解释了两种类型报警器的性能差异，并指出了哪种报警器最适合家庭使用。

标准中列出了不同火灾试验，其设计目的是遇到不同火灾时，使用正确的技术，确保真实发生火灾时，烟雾报警器能及时给予足够的警告。试验旨在测量烟雾报警器对火灾早期的反应，这是为了确保在真实发生火灾时报警器能及时给予足够的警告。  

针对上个月的询问，BSI把这些证据提交给有关部门。按照正常程序，该项标准目前正处于审查阶段，因此我们把证据提供给有关部门，他们将会把最新调查结果提交给专家委员会，届时我们再考虑是否有需要做的事情，并建议他们加入委员会，帮助协调专家和公益团体。BSI期待有关部门的早日答复。

BSI并未对所有产品进行Kitemark^TM认证。有关部门声称，未经认证的Devolo报警器在四次试验中失败达两次。其它报警器可能经独立第三方测试认证，但仍需检查其是否符合标准的要求。 

BSI response to Which? article on smoke alarms

BS EN 14604 is a well-established and respected standard that has been utilized by government, regulators and the industry alike for a number of years to define best practice for smoke alarm devices.

The standard covers the main two types of smoke alarm, optical and ionisation, and clearly recognizes that they will behave differently depending upon the type of fire scenario they are being tested to. This latest research by Which? attempted to compare these two

different types of alarm side by side across 4 differing test scenarios.  The Which? article itself very clearly explains the difference in performance between the two types of alarm, and suggests where each might be best used in the home.

The test fires set out in the standard are designed to ensure that whichever technology is used, or the type of fire encountered, the smoke alarm provides adequate warning in the event of a real fire. The tests conducted are designed to measure the smoke alarms

response to the very early stages of a developing fire. This is to ensure the smoke alarm provides adequate warning in the event of a real fire.  

BSI provided these facts to Which? in response to an enquiry last month. The standard is currently under review, as part of a normal review process, and therefore we have offered Which? the opportunity to present their latest findings to our expert committee to see if

anything might need to be done, and suggested that they might also wish to consider joining the committee that compromises a range of experts and public interest groups. BSI looks forward to hearing from Which?.

BSI has not Kitemark^TM certified all of these products and BSI did not certify the Devolo alarm that Which? claimed failed two of the four tests.  Others may have been tested and certified by different independent third parties to check it meets the requirements of the

standard.
