本产品标准规定了干燥（指定的D）和/或湿（指定的W）空气烟道系统烟囱的要求和测试方法，包括通过粘土/陶瓷烟道衬里和燃烧空气将燃烧产物输送到大气的终端通过空气管道或气隙输送到合适的室内密封设备。 它还规定了标记，制造商的说明书，产品信息和符合性评估的要求。 本标准不适用于结构独立（自立或自支撑）系统烟囱。 一个空气烟道系统烟囱由以下组成部分组成: - 粘土/陶瓷烟道衬里; - 绝缘层; - 外墙; - 连接烟道衬里的砂浆; - 用于连接烟道衬板的耐酸砂浆或弹性密封剂; - 用于连接外墙的砂浆; - 终奌站; - 烟囱基地 - 均压开口; - 风道; - 气隙; - 包层 - 开放部分; - 清洁和检查门; - 距离片 - 加固。 烟道系统烟囱涵盖从一个制造来源获得或指定的兼容烟囱组件的组合，对整个烟囱负责产品

This product standard specifies the requirements and test methods for dry (designated D) and/or wet (designated W) air flue system chimneys, including terminals in which the products of combustion are conveyed to the atmosphere through clay/ceramic flue liners and combustion air is conveyed to suitable room-sealed appliances through an air duct or an air gap. It also specifies the requirements for marking, manufacturer's instructions, product information and evaluation of conformity. This standard does not apply to structurally independent (free standing or self supporting) system chimneys. An air flue system chimney is made of the following components where appropriate: - clay/ceramic flue liners; - insulation layer; - outer walls; - mortar for jointing flue liners; - acid resistant mortar or elastomeric sealant for jointing flue liners; - mortar for jointing outer walls; - terminal; - chimney base; - pressure equalising opening; - air duct; - air gap; - cladding; - opening section; - cleaning and inspection door; - distance piece; - reinforcement. The air- flue system chimney covers a combination of compatible chimney components obtained or specified from one manufacturing source, with product responsibility for the whole chimney.
