What is BS EN 10181 - Determination of lead content about?
BS EN 10181 is a safety standard on steels.
BS EN 10181 specifies a flame atomic absorption spectrometric method (FAAS) for the determination of lead content in non-alloy and low alloy steels.
Note 1: The method is applicable to lead contents between 0,005 % (weight percent) and 0,5 % (weight percent).
Note 2: The method can be adapted to lower or higher lead 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 10181 - Determination of lead content for?
BS EN 10181 on determining lead 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 10181 - Determination of lead content?
The major component of steel is iron, a metal that in its pure state is not much harder than copper.
BS EN 10181 assists the user with the dissolution of a test portion in hydrochloric acid followed by oxidation with nitric acid. BS EN 10181 also assists in the nebulization of the test solution into an air/acetylene flame of an atomic absorption spectrometer.
Overall, BS EN 10181 is useful as it guides on the standard deviation of 10 measurements of the absorbance of the most concentrated calibration solution.
