GB/T 10574.14-2017 is the Chinese national standard on methods for chemical analysis of tin-lead solders - part 14: determination of tin, lead,antimony,bismuth,silver,copper,zinc,cadmium and arsenic content - optical emission spectrometry, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 October 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2018. Classification: ICS 77.120.60, CCS H13. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

67.00 Pb 32.50 ~

3 Method summary

The prepared massive sample was used as one electrode, a light source generator was used to excite the light between the sample and the counter electrode, and the light beam was introduced Splitting chamber, after the spectral dispersion of the system to form a spectrum, the selected spectral lines through the photoelectric conversion system and measurement system for photoelectric conversion and measurement Spectral line intensity, according to the working curve of the standard sample to determine the mass fraction of the test element in the sample.
