Foreword
This document was drafted in accordance with the provisions of GB/T 1.1-2020
"Directives for standardization - Part 1.Rules for the structure and drafting of
standardizing documents".
This document replaces GB/T 469-2013 "Lead ingots". Compared with GB/T 469-2013,
in addition to structural adjustments and editorial changes, the main technical changes
are as follows.
a) CHANGE the scope, changing "This standard applies to lead ingots produced by
electrolysis or pyrolysis refining" to "This document applies to lead ingots
produced by electrolysis refining" (see Chapter 1; Chapter 1 of the 2013 edition);
b) ADD the Pb99.996 designation; DELETE the four designations Pb99.990,
Pb99.985, Pb99.970, Pb99.940 (see Chapter 4; 3.1 of the 2013 edition);
c) CHANGE the content requirements of impurity elements Ag, Cu, Bi in the
designation Pb99.994, from 0.0008%, 0.001%, 0.004% to 0.0007%, 0.0008%,
0.0025%, respectively (see Table 1; Table 1 of the 2013 edition);
d) DELETE the physical specifications of small ingots of 40 kg ± 2 kg (see 3.3.2 of
the 2013 edition).

judgement of limiting values
3 Terms and definitions
There are no terms or definitions to be defined in this document.
4 Categories
Lead ingots are divided into 2 designations according to their chemical composition.
5 Technical requirements
5.1 Chemical composition
5.1.1 The chemical composition of lead ingots shall comply with the requirements in
Table 1.
5.1.2 When lead is used to produce an alloy, which has an element listed in Table 1 as
an additive element, the content of this element does not need to be limited by the
maximum value specified in Table 1; it can be agreed upon by the supplier and the buyer.
5.2 Physical specifications
5.2.1 Lead ingots are divided into large ingots and small ingots. The small ingot is
rectangular and trapezoidal, with a bundling groove at the bottom and protruding ears
at both ends.

5.3.1 There shall be no slag, molten holes, granular oxides, inclusions, external
contamination on the surface of lead ingots.
5.3.2 The lead ingot shall not have cold insulation; it shall not have flash burrs larger
than 10 mm (trimming is allowed).
5.4 Others
If the buyer has special requirements for the chemical composition, physical
specifications, surface quality, etc. of lead ingots, they can be negotiated by the supplier
and the buyer.
6 Test methods
