Acoustics. Laboratory tests on noise emission from appliances and equipment used in water supply installations - Mounting and operating conditions for in-line valves and appliances shop-only 11 Description of SF6 handling1 Scope This document specifies the mounting and operating conditions to be used for in line valves and appliances which control the flow, pressure or temperature of the water in water supply installations, when measuring noise emission resulting from water flow. It is applicable to in line valves and appliances of maximum nominal size DN 32 and to systems in which the maximum water flow rate does not exceed 1,6 l s. NOTE See ISO 6708; DN is the
