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

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
