DESCRIPTION
BS EN ISO 3822-3:2018
This standard BS EN ISO 3822-3:2018 Acoustics. Laboratory tests on noise emission from appliances and equipment used in water supply installations is classified in these ICS categories:
- 17.140.20 Noise emitted by machines and equipment
- 91.140.60 Water supply systems
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 symbol for “nominal size”. The number of the nominal size is loosely related to the inside diameter (in millimetres) of the in-tine valves and appliances.
The procedures described are for general use for all types of in-line valves of conventional design.
