烟雾和热控制系统 第6部分：压差系统的规范

[中文适用范围]： 本文件适用于投放市场并旨在作为压差系统一部分运行的压差系统套件和组件。压差系统的目的是通过使用压差和气流来防止烟雾扩散到受保护空间。本文件规定了用于在受保护空间和未受保护空间之间产生和控制所需压差和气流的压差系统组件和套件的特性和测试方法。 [外文原描述]： This document applies to pressure differential system kits and components, positioned on the market and intended to operate as part of a pressure differential system. The purpose of a pressure differential system is to prevent protected spaces from smoke spread by using pressure difference and airflow. This document specifies characteristics and test methods for components and kits for pressure differential systems to produce and control the required pressure differential and airflow between protected and unprotected space.
