标准范围

ISO 21927-8:2017适用于市场上销售的、作为压差系统或烟热控制系统一部分运行的防烟挡板。本文件规定了烟雾控制风门及其相关部件（如拟安装在建筑物内此类系统中的致动器）的要求，并参考了规定的试验方法。此外，还提供了有关标记的规定以及这些产品的安装和维护信息。ISO 21927-8:2017区分了两类烟雾控制挡板，即单室烟雾控制挡板和多室耐火烟雾控制挡板。本文件所述的防烟挡板可安装在防烟系统管道内或管道表面。它们也可以安装在墙壁、地板或天花板/屋顶构件中，或安装在这些构件的表面上。注:为避免重复，参考了各种其他标准。为此，可结合EN 13501-4、EN 1366-10和ISO 10294-1阅读本文件，以了解熔炉测试的详细信息。ISO21927—8:2017没有详细考虑在大气中存在的过程化学品所引起的有害和/或腐蚀作用，这些物质是有意或无意地通过系统吸入的。

ISO 21927-8:2017 applies to smoke control dampers, placed on the market and intended to operate as part of a pressure differential system or smoke and heat control system. This document specifies requirements and gives reference to the test methods defined for smoke control dampers and their associated components, such as actuators which are intended to be installed in such systems in buildings. Furthermore, provision on marking and information on installation and maintenance of these products are also given.ISO 21927-8:2017 distinguishes between two categories of smoke control dampers, i.e. single-compartment smoke control dampers and multi？compartment fire-resisting smoke control dampers.Smoke control dampers covered by this document can be installed into smoke control system ducts or onto the ducts' surface. They can be installed also into a wall, floor or ceiling/roof elements or onto the surface of these elements.NOTE To avoid duplication, reference is made to a variety of other standards. To this end, this document can be read in conjunction with EN 13501？4, EN 1366？10 and ISO 10294？1 for details of the furnace testing.ISO 21927-8:2017 does not consider in detail the detrimental and/or corrosive effects that can be caused by process chemicals present in the atmosphere, which are drawn through the system intentionally or inadvertently.
