1 Scope

GB/T 26289-2010 is the Chinese national standard on methods for chemical analysis of high purity selenium determination of boron,aluminum,iron,zinc,arsenic, silver, tin, antimony, tellurium, mercury, magnesium,titanium,nickel,copper,gallium,cadmium,indium,lead and bismuth contents inductively coupled plasma mass 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 January 2011 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 November 2011. Classification: ICS 77.120.01, CCS H14. 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 standard specifies the selenium in high purity boron, aluminum, iron, zinc, arsenic, silver, tin, antimony, tellurium, mercury, magnesium, titanium, nickel, copper, gallium, cadmium, indium, lead, bismuth impurity element Measurement method. This standard applies to the measurement of high purity selenium and boron, aluminum, iron, zinc, arsenic, silver, tin, antimony, tellurium, mercury, magnesium, titanium, nickel, copper, gallium, cadmium, indium, lead, bismuth content set.
