6、tandard #1062-2017This foreword shall not be considered a part of the standard; however, it is offered to provide background information.Exposure to high temperature water can result in serious injuries. This problem has been publicized by consumer safety organizations and is addressed in ASTM F444-

7、88, Standard Consumer Specification for Scald-Preventing Devices and Systems in Bathing Areas.This standard covers point of use temperature actuated, flow reduction (TAFR) valves that are installed in-line with, or integrated into, supply fittings. These valves automatically reduce discharge flow to

8、 a trickle if water temperature exceeds a preset limit. Other ASSE standards, such as ASSE 1016/ASME A112.1016/CSA B125.16, ASSE 1017, ASSE 1066, ASSE 1069, and ASSE 1070/ASME A112.1070/CSA B125.70, have been developed for hot and cold water mixing valves that limit discharge temperature, and in-lin

9、e pressure balancing valves that minimize pressure variations between the hot and cold water supplies. TAFR valves are not intended to be installed in place of devices complying with ASSE 1016/ASME A112.1016/CSA B125.16, ASSE 1017, ASSE 1066, ASSE 1069, or ASSE 1070/ASME A112.1070/CSA B125.70. ASSE
