All spray taps shall also meet the following criteria:

Hydraulic Characteristics:

When tested using the method and apparatus described in section 12 of 5388:1976 or section 12 of BS 5779:1979 as appropriate, but using dynamic pressures at the inlet to the tap up to and including 5 bar +/- 0.2 bar, the measured flowrate shall not exceed 6 litres/minute.

If a flow regulator is required to be fitted to the spray tap to limit the flowrate to 6 litres/minute at 5 bar, the tap and the flow regulator must be sold as one product.

Where the tap is supplied with a flow straightner fitting, the two components must be sold as one product.
