GB/T 17433-2014Foundation terms for chemical analysis of metallurgical products (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 17433-1998 "metallurgical products chemical analysis of the term." This standard and GB/T 17433-1998 phase

Ratio, the main changes are as follows.

--- Remove the "reference standard";

--- 2.1 "General" increased detection, parallel determination, volume, value, quality, mass fraction, volume fraction, atom%, the basic single

Yuan, relative atomic mass, relative molecular mass, concentration, purity, content, background equivalent concentration calibration (see 2.1.2,2.1.4,

2.1.8,2.1.9,2.1.10,2.1.11,2.1.12,2.1.13,2.1.15,2.1.17,2.1.18,2.1.21,2.1.24,2.1.25,2.1. 30, 2.1.32); revised chemical analysis, measurement, detection limit, the amount of substance, molar mass, sensitivity, detection limit, the calibration curve, standard

Quasi-added method, ambient temperature and pressure (2.1.1,2.1.3,2.1.7,2.1.14,2.1.22,2.1.23,2.1.29,2.1.33,2.1.38,2.1.39, 2.1.40);

--- 2.2 "Analysis" added iodometry, non-aqueous titration [method], Karl Fischer titration [method], electrolytic method, rare isotope

Release mass spectrometry, glow discharge mass spectroscopy, Kjeldahl method, ion chromatography analysis of trace components (2.2.2.6,2.2.2.11,

2.2.2.12,2.2.2.25,2.2.2.34,2.2.2.36,2.2.2.42,2.2.2.44,2.2.4.4); amended by the purpose of the task, according to the principle,

Weighing Analytical [method], fire assay, according to the test quantity, in a sample of mass fraction of component being tested by the analysis of trace components as required

(2.2.1,2.2.2,2.2.2.3,2.2.2.38,2.2.3,2.2.4,2.2.4.3,2.2.5) and other entries;

--- 2.3 "sample" in the revised sampling, sample preparation, quartering (2.3.1.1,2.3.1.2,2.3.1.4);

Increase --- 2.4 "agents" in the standard reference material, mixed indicator, surfactants, emulsifiers, coagulant (2.4.1.3,2.4.2.6,

2.4.3.12,2.4.3.13,2.4.3.14); revised standard material/standard sample certification (certified) reference material/standard samples, standard

Standard solution, the standard stock solution, the calibration gas, water, ultrapure water (2.4.1.1,2.4.1.2,2.4.1.6,2.4.1.7,2.4.1.12, 2.4.3.5,2.4.3.7);

1 Scope

This standard specifies the chemical analysis of metallurgical products basic terminology.

This standard applies to the preparation of metallurgical products for chemical analysis of national standards, industry standards, corporate standards. Preparation of technical documents, books and school

Operation and exchange of technology can also be applied in business dealings.
