2.12 Water Quality
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 sterlizers
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
Compliance with the above data should be tested in accordance
with acknowledged analytical methods, by an authorized
laboratory.
Attention:
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.
