Notes:
The values for the inorganic substances were measured in a sample of water which was taken after two minutes' opera-
tion at a flow of 4.4 litres per minute, 80 % recovery and a challenge water with a salt content of 800 mg per litre at a
temperature of 20 °C. Test laboratory: VVL, Stockholm (Sweden).
The values for the organic substances were measured in a sample which was taken after two minutes' operation at a flow
of 2.8 litres per minute, 80 % recovery and a challenge water to which was added each relevant substance to a concentra-
tion which is 100 times higher than the lowest detectable quantity at a temperature of 10°C. Test laboratory: AnalyCen,
Lidköping (Sweden).
Microbiological testing was carried out under a range of operating conditions with a challenge water containing a very
great number of microorganisms. The water samples were collected weekly after operating times of 20 and 40 seconds
and 1, 2, 6, 12 and 18 minutes. Test laboratory: SVELAB, Jönköping (Sweden).
