CERTIFIED REFERENCE MATERIALS CRM CZ 02033
Cast iron for solid sample spectrometry, CRM set 1-8 (valid till 2027)
Intended for calibration, validation and matrix-match verification of cast iron
spectrometric analysis from a plain solid sample: Atomic Emission Spectrometry with
spark, glow-discharge or laser excitation, and X-ray Fluorescence Spectrometry.
Eight CRM # 1 – # 8 represent the most frequent unalloyed and low alloy cast iron
types in sequence: unalloyed ductile iron, Ni-Cu ductile iron, vermicular iron (CGI),
pig iron, malleable iron, Mn-Cr-V and Ni-Mo alloyed iron and plain grey iron.
Supplied in a set or as individual discs, 40 mm diameter and approx. 18 mm of total
height, with two certified layers extending 6 mm upwards from either working
surface. The discs are marked with the CRM code and the certified layers' limits.
When used to both limits, the remainder, which may contain minor structure defects,
should be discarded.
