Testing of heads using BS 8548:2015
« on: April 18, 2018, 11:00:54 AM »
The above standard does not state that a mist head in its entirety should be tested I.e nozzle and cover plate.

Therefore what's the view of the forum when a manufacturer has a head tested, then subsequently develops the head changing the orientation of the bulb but leaving the multiple water orifice the same and adding an aesthetic cover plate onto the head.

New test required or previous test sufficient?

My gut feel is that it is effectively a new head and new test is required as the cap and bulb orientation may change the reaction time therefore room temperature despite the same water pattern, flow and pressure.

The manufacturer has since produced a separate test for just the cap however the temperature used to activate the cap was 135C.

I would interested in the thoughts and opinions of the forum.
