What is BS EN 10177 - Determination of calcium content about?
BS EN 10177 is a safety standard on steels.
BS EN 10177 specifies a flame atomic absorption spectrometric method (FAAS) for the determination of calcium content in non-alloy and low alloy steels.
Note 1: The method is applicable to calcium contents between 4 μg/g and 120 μg/g.
Note 2: The method can be adapted to higher calcium contents by changing the test portion of the dilution process, provided the criteria in 6.2.2 and 6.2.3 are still met.
Who is BS EN 10177 - Determination of calcium content for?
BS EN 10177 on determining calcium content is relevant to:
- Manufacturers of an atomic absorption spectrometer
- Suppliers of steels
- Metalworkers
- Chemical engineers
- Testing authorities
- Environmental engineers
Why should you use BS EN 10177 - Determination of calcium content?
The major component of steel is iron, a metal that in its pure state is not much harder than copper.
BS EN 10177 assists the user with the dissolution of a test portion of hydrochloric acid followed by oxidation with nitric acid.
Overall, BS EN 10177 is useful as it guides on the standard deviation of 10 measurements of the absorbance of the most concentrated calibration solution.
