GB/T 11066 "Chemical Analysis Methods for Gold" has been published in 11 parts, covering silver, iron, copper, lead, bismuth, antimony, magnesium, nickel, palladium, manganese, chromium, arsenic, However, as gold refineries, raw material suppliers, consumers, third-party arbitration institutions and intermediary traders have been Gold quality control is becoming increasingly strict, and the types of impurity elements required to be tested for gold ingots are increasing, and the testing time requirements are becoming higher and higher; therefore, efficient and accurate It is particularly important to accurately detect the chemical composition of gold: GB/T 11066 consists of 12 parts according to different test objects and test methods: constitute:

1 Scope

GB/T 11066.12-2024 is the Chinese national standard on methods for chemical analysis of gold - part 12: determination of silver, copper, iron, lead, bismuth, antimony, magnesium, nickel, manganese, palladium, chromium, platinum, rhodium, titanium, zinc, arsenic, tin, silicon, cobalt, calcium, potassium, lithium, sodium, tellurium, vanadium, zirconium, cadmium, molybdenum, rhenium, aluminum contents - inductively coupled plasma atomic 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 25 April 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 November 2024. Classification: ICS 77.040.30, CCS H15. 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.

This document describes the silver, copper, iron, lead, bismuth, antimony, magnesium, nickel, manganese, palladium, chromium, platinum, rhodium, titanium, zinc, arsenic, tin, silicon, cobalt, calcium, potassium, lithium, Methods for determination of sodium, tellurium, vanadium, zirconium, cadmium, molybdenum, rhenium and aluminium contents: This document applies to silver, copper, iron, lead, bismuth, antimony, magnesium, nickel, manganese, palladium, chromium, platinum, rhodium, titanium, zinc, arsenic, tin, silicon, cobalt, calcium, potassium, lithium, Determination of the content of sodium, tellurium, vanadium, zirconium, cadmium, molybdenum, rhenium and aluminum: The determination range of each element is shown in Table 1: Table
