Scope
GB/T 4103.9-2012 is the English-translated version of 铅及铅合金化学分析方法 第9部分：钙量的测定.
GB/T 4103.9-2012 is Part 9 of GB/T 4103, the sixteen-part series on methods for chemical analysis of lead and lead alloys, and it covers the determination of calcium content.
Clause 1 states that the part specifies and applies to the determination of calcium content in lead and lead alloys.
After the foreword, Scope and Normative references, a general clause requires reagents recognised as analytically pure, water complying with GB/T 6682, instruments within their verification period and grade A glassware as specified in GB/T 12806, GB/T 12808 and GB/T 12809, used as set out in GB/T 12810.
The method clause is flame atomic absorption spectrometry: its determination range covers the calcium content of lead-calcium alloy ingot for battery grids, secondary lead-calcium alloy, hard lead-antimony alloy and special hard lead-antimony alloy from 0.010% to 1.000% as a mass fraction, and its principle is to dissolve the sample with nitric acid and tartaric acid and to measure the absorbance of calcium at a wavelength of 422.7 nm in an air-acetylene flame atomic absorption spectrometer, with lanthanum salts as the releasing agent.
The foreword records that the determination range was extended with respect to the previous edition and that precision provisions were added; the draft on the page breaks off among the reagents, so the remaining clauses of the part are not shown.
Clause 2 cites GB/T 6682, GB/T 12806, GB/T 12808, GB/T 12809 and GB/T 12810, and the committee named as being in charge is SAC/TC243. It replaces GB/T 4103.9-2000, was issued on 31 December 2012 and has applied since 1 October 2013.
