AS 4072.1：耐火隔离构件的开口保护组件检修穿透和控制接缝
AS 4072.1耐火隔离构件的开口保护组件检修穿透和控制接缝 – 适用范围
本标准规定了对密封系统进行耐火性测试的结构，安装和应用的最低要求-（a）穿过贯穿的，穿过具有一定耐火水平（FRL）或（如果适用）耐火性的分离建筑构件的贯穿孔火的初期蔓延；和（b）在要求具有耐火等级（FRL）的建筑构件之间的控制接缝处。
This Standard sets out minimum requirements for the construction, installation and application of fire resistance tests to sealing systems – (a) around penetrations through separating building elements that are required to have a fire resistance level (FRL) or, if applicable, a resistance to the incipient spread of fire; and (b) at control joints between building elements that are required to have a fire resistance level (FRL).
