For the gravimetric method, the sample length shall in accordance with Table 1 in EN 10244-4. 5.2.2 Gravimetric method 5.2.2.1 Procedure If necessary, degrease the sample with a suitable solvent. Weigh the samp

27、le to an accuracy of 0,l mg.(mass mi). Strip the samples in concentrated nitric acid (“OJ) with a density of 1,4 at 20 “C. After stripping, rinse the samples, dry them and once again weigh them to the same accuracy (mass r&). If the mass difference is less than 10 mg, repeat the test with a suitably

28、 longer sample. Determine the diameter of the wire. 5.2.2.2 The calculation shall be carried out in accordance with EN 10244-1 using the following formula: Calculation of mass of coating STDeBSI BS EN L0244-5-ENGL 2001 1b24bb9 090931b 408 Page 6 EN 10244-512001 5.2.3 Use of atomic absorption spectro

A more accurate method involves determining the quantity of nickel in a defined volume of pickling solution using an atomic absorption spectrometer. NOTE low carbon steels,

The possible error in using the gravimetric method may be smaller with high carbon steels than with 5.3 Adherence test The adherence test shall be carried out in accordance with EN 10244-1 using a mandrel with a diameter three times the diameter of. me wire. Under t
