3.1.2 water spray nozzle
A water discharge device that, when discharging water under pressure, will distribute the water in a specific directional pattern.
4 Product consistency
It shall be the responsibility of the manufacturer to implement a quality control program to ensure that production continuously meets the requirements of this part of ISO 6182.
5 Product assembly
5.1 Design features
All nozzles shall be designed and manufactured in such a way that they cannot be readily adjusted. dismantled or reassembled.
5.2 Materials of construction

6 Requirements
6.1 Dimensions
6.1.1 OrIfice Size
6.1.1.1 Except as permitted in 6.1.1.2, All nozzles shall be constructed so that a sphere of diameter 5 mm can pass through each water passage in the nozzle.
6.1.1.2 Nozzles having orifices smaller than a nominal 5 mm diameter are permitted if the orifices are protected with a strainer in the system or in each nozzle. The maximum dimension of an opening in the strainer shall not exceed 80 % of the smallest water passageway being protected and the total open area of the strainer shall not be less than 150% of the total nozzle orifice area.
Note: If there is no risk of corrosion or water deposits, then an orifice less than 5 mm could be used without a strainer, See the manufacturer’s installation instruction requirements in Clause 9.
