English term or phrase: hardness as

Hallo,

ich übersetze gerade Etiketten für Laborgeräte, und ich habe Probleme mit dem Ausdruck "Total water hardness ≤ 140 ppm hardness as CaCO3" nicht.

Hier ist der zugehörige Text:

changing the filter cartridges, turn off potable water supply and press
pressure relief button to release water pressure. Replace filter cartridges.
CAUTION: To Assure Proper Operation
• STERIS Corporation’s dual filter combination must be used
• Inlet water supply must be potable (i.e., drinkable water)
• ****Total water hardness ≤ 140 ppm hardness as CaCO3****
• Use with water temperature between 43°C - 60°C (109°F – 140°F)
• Set water pressure regulator to 45 psig at the outlet
• Do not exceed 80 psig inlet water supply pressure
• Only use STERIS filters to ensure the system’s maximum allowable
water flow

Bedeutet das, dass die Wasserhärte genau so hart wie CaCO3 sein soll? Das ergibt meine Ansicht nach nicht sehr viel Sinn...

Vielen Dank für eure Hilfe!

German translation:Wasserhärte in ppm CaCO3

Explanation:
Hallo Egmont,

das internationale Einheitensystem, das am weitesten verbreitete Einheitensystem für physikalische Größen, legt die Einheit für die Wasserhärte als mol/l bzw. in Anbetracht der kleinen Konzentrationen in mmol/l fest. Daneben gibt oder gab es aber in verschiedenen Ländern verschiedene Maßeinheiten für die Wasserhärte. Die Einheit der USA ist ppm CaCO3. Ich denke, das ist hier gemeint.

Hier eine Referenz:
https://de.wikipedia.org/wiki/Wasserhärte#Einheiten_und_Umre...

Ich hoffe, es hilft!
