5 WATER QUALITY
5.1 Water for Generating Steam
The distilled or mineral – free water supplied to the sterlizer shall be
according to the table below:
Physical Characteristics and Maximum acceptable contaminants
levels in steam for sterlizers
(According to EN 13060:2004).
Element Condensate – allowable content
Silicium oxide. SiO
2
≤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
2
O
5
) ≤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:
We recommend testing the water quality once a month. The use of
water 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 guarantee.
5.2 Reverse Osmosis
A Reverse Osmosis system may be used to improve the quality of the
water used to generate steam in the autoclave chamber. The use of
mineral free will contribute to better performance and longer life of the
autoclave.
