2.9 Water Quality
2.9.1
Water for Steam Generation
The distilled or mineral – free water supplied to the autoclave
should have the physical characteristics and maximum
acceptable level of contaminants indicated in the table below:
Physical Characteristics and Maximum acceptable
contaminants levels in steam for sterilizers
(According to EN 13060:2004).
Element
Condensate –
allowable content
Silicium oxide. SiO

≤ 0.1 mg/kg
Iron ≤ 0.1 mg/kg
Cadmium ≤ 0.005 mg/kg
Lead ≤ 0.05 mg/kg
Rest of metals except iron,
cadmium, lead
≤ 0.1 mg/kg
Chloride (Cl) ≤ 0.1 mg/kg
Phosphate (P

) ≤ 0.1 mg/kg
Conductivity (at 20°C) ≤ 3 µs/cm
pH value (degree of acidity) 5 to 7
Appearance
Colourless clean without
sediment
Hardness ( Σ Ions of alkaline earth) ≤ 0.02 mmol/l
The suitability of the water to be used should be verified by
testing in accordance with the above table, at an authorized
laboratory using acknowledged analytical methods.
Attention:
We recommend testing the water quality once a month. The
use of water for autoclaves that does not comply with the table
above may have severe impact on the working life of the
sterilizer and can invalidate the manufacturer’s warranty.
