However, it is offered to provide background information.Water mixing, also defi
6、ned as tempering or blending, valves are used extensively in applications for emergency shower/eye and face wash systems to mix hot and cold water to provide “tepid” water. The term “tepid” has not been specifically defined, but is generally understood to mean “lukewarm” or “moderately warm.”These d
7、evices, while designed for automatic control of the hot water temperature within a reasonable degree of uniformity, should not be confused or used in place of ASSE Standard 1016, 1017, 1069 or 1070 devices. Valves designed to meet this standard are intended to be used as a component that can provide
8、 tepid water for emergency eye wash and shower equipment that comply with the requirements of ANSI Z358.1, American National Standard for Emergency Eyewash and Shower Equipment. These valves, by themselves, do not meet the requirements of ANSI Z358.1.In circumstances where chemical reaction is accel
9、erated by flushing fluid temperature, per ANSI Z358.1, a medical advisor should be consulted for the optimum temperature for each application.The working group, which developed this standard revision, was set up within the framework of the Product Standards Committee of the American Society of Sanit
10、ary Engineering.Recognition is made of the time volunteered by members of this working group and of the support of the manufacturers who also participated in the meetings for this standard.This standard does not imply ASSEs endorsement of a product which conforms to these requirements.Compliance wit
11、h this standard does not imply acceptance by any code body.It is recommended that these devices be installed consistent with local codes by qualified and trained professionals.This standard was promulgated in accordance with procedures developed by the American National Standards Institute (ANSI).Th
12、is edition of the standard was approved by the ASSE Board of Directors on August 30, 2012 as an ASSE standard.iv Temperature Actuated Mixing Valves for Plumbed Emergency EquipmentASSE 1071-2012Joseph Fugelo, ChairmanLabov Co.Philadelphia, Pennsylvania Rand AckroydRand Technical Consulting, LLCNewbur
