What is BS EN 10136 - Determination of nickel content about?
BS EN 10136 is a safety standard on steels and cast irons.
BS EN 10136 specifies a flame atomic absorption spectrometric method (FAAS) for the determination of nickel content in steels and cast irons. The method is applicable to nickel contents between 0,004 % (weight percent) and 2,0 % (weight percent).
The method can be adapted to lower or higher nickel 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 10136 - Determination of nickel content for?
BS EN 10136 on determining nickel content is relevant to:
- Manufacturers of atomic absorption spectrometers
- Suppliers of steels and cast irons
- Metalworkers
- Chemical engineers
- Testing authorities
- Environmental engineers
Why should you use BS EN 10136 - Determination of nickel content?
Cast iron is a group of iron-carbon alloys with a carbon content of more than 2%. The carbon in typical steel alloys may contribute up to 2.14% of its weight.
BS EN 10136 assists the user with the dissolution of a test portion in a mixture of appropriate acids and fuming with perchloric acid. BS EN 10136 also assists with the nebulization of the test solution into an air/acetylene flame of an atomic absorption spectrometer. Spectrometric measurement of the atomic absorption of the 232,0 nm or 352,5 nm spectral line emitted by a nickel hollow-cathode lamp.
Overall, BS EN 10136 is useful as it guides on the standard deviation of 10 measurements of the absorbance of the most concentrated calibration solution.
