Na: p1 ≤ 0,5 bar; Nb: p1 > 0,5 bar
6)
For components made of bronze: ammonia (NH3) ≤ 5 mg/kg, free from hydrogen sulphide (H2S); no limitation of
CI content required in this case. Please contact KSB if limits are exceeded.
7)
General evaluation criteria for results of water analysis: pH value ≥ 7; chlorides content (Cl) ≤ 250 mg/kg. Chlorine
(Cl2) ≤ 0.6 mg/kg.
8)
Treatment to VdTÜV 1466; additional requirement: O2 < 0.02 mg/l
