ASSE 1053规定了防冻双止回防回流器壁式消防栓的设计和性能要求，该消防栓可保护饮用水供应免受反虹吸和背压的影响，且不会因冻结而损坏设备。为了验证螺纹软管出口处存在的高危险条件下的保护，这些装置必须是可现场测试的。ASSE 1053装置分为A型或B型。A型装置在消防栓阀门关闭且软管拆除以防止冻结损坏时自动排水，B型装置在软管拆除或连接、端喷嘴关闭且消防栓阀门关闭时自动排水。

ASSE 1053 establishes design and performance requirements for Freeze Resistant Dual Check Backflow Preventer Wall Hydrants, which protect the potable water supply against backsiphonage and backpressure without damage to the device due to freezing. To verify protection under the high hazard conditions present at threaded hose outlets, these devices must be field-testable.ASSE 1053 devices are classified as Type A or Type B. Type A devices automatically drain water when the hydrant valve is closed and the hose is removed to prevent damage from freezing, and Type B devices automatically drain water with a hose removed or attached, end nozzle closed, and the hydrant valve closed.
