Science - Physics / radioactive waste disposal

From a document describing the testing for radioactive waste containers:

"I provini, sono quindi immersi per 90 giorni in acqua dolce (durezza non maggiore di 15 gradi francesi), a temperatura ambiente"

French degrees
Explanation:
La durezza viene espressa convenzionalmente in gradi idrotimetrici: il complesso dei sali presenti è calcolato come carbonato di calcio o come ossido di calcio.

In particolare:
- un grado francese corrisponde a 1 g di carbonato di calcio contenuto in 100 l d’acqua, ossia 0,01 g/l diCaCO3;
- un grado tedesco corrisponde a 1 g di ossido di calcio in 100 litri d’acqua;
- un grado inglese corrisponde a 1 g di carbonato di calcio per 70 litri di acqua.

French degrees (°f) (shares symbol with degree Fahrenheit, but in lowercase)
- conversion to mg/L calcium: divide by 0.25
One degree French corresponds to one part calcium carbonate in 100,000 parts of water.
