8、 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 understoodto mean “lukewarm“ or “moderately warm“.These devices, while designed for automatic control of the hot water temperature withi
9、n areasonable degree of uniformity, should not be confused or used in place of the ASSE Stan-dard 1016, 1017, 1069 or 1070 devices. Valves designed to meet this standard are intendedto be used as a component that can provide tepid water for emergency eye wash and showerequipment that comply with the
10、 requirements of ANSI Standard Z358.1. These valves, bythemselves, do not meet the requirements of ANSI Standard Z358.1.In circumstances where chemical reaction is accelerated by flushing fluid temperature, perANSI Z358.1 a medical advisor should be consulted for the optimum temperature for eachappl

39、Performance Requirements and Compliance Testing3.1 Conditioning Test3.1.1 PurposeThe purpose of this test is to verify that the device continues to function when subjected to atemperature of 200.0 F (93.3 C) at a flowing pressure of 125.0 psi (861.9 kPa).3.1.2 ProcedureInstall the device as shown in
40、 Figure 1, except supply hot water to both cold water and hot waterinlets. Open valve V2 fully. Open valve V1 sufficiently to allow hot water to bleed through the deviceto maintain a temperature of 200.0 F 5.0 F (93.3 C 2.8 C) at T3, and maintain a pressureof 125.0 psi 5.0 psi (861.9 kPa 34.5 kPa) a
