This document replaces GB/T 3653:1-1988 "Chemical analysis method of ferroboron - Alkali titration method for determination of boron content" and is consistent with GB/T 3653:1-
Compared with 1988, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Anhydrous sodium carbonate has been added (see 5:1);
b) The sodium hydroxide is prepared in boiled water (see 5:11:1, 3:10:1 of the 1988 edition);
c) Added analytical balance (see 6:2);
d) Increased the number of measurements (see 8:2);
e) Added the presentation of results (see 9:2);
f) Repeatability limit and reproducibility limit are used instead of allowable error (see Chapter 10, Chapter 8 of the 1988 edition);
g) Added the content of test report (see Chapter 11):

Introduction
Since there are many detection elements involved in the ferroboron detection process, the applicable scope and application methods of the elements are different:
The convenience and accuracy of iron detection standards, we have established a national standard system to support the detection of ferroboron for the analysis methods of different elements of ferroboron:
GB/T 3653 series of ferroboron analysis methods is the basic standard for ferroboron detection in my country, and is intended to consist of the following 7 parts:
--- Part 1: Determination of boron content in ferroboron by alkali titration:
Establish the law:
--- Part 2: Chemical analysis of ferroboron - Determination of carbon content by gas volumetric method: The purpose is to measure the carbon content in ferroboron using gas volumetric method:
Volumetric method:
--- Part 3: Determination of silicon content in ferroboron - Perchloric acid dehydration gravimetric method: The purpose is to measure the silicon content in ferroboron using a high
Chlorate dehydration gravimetric method:
--- Part 4: Determination of aluminum content in ferroboron - EDTA titration method: The purpose is to measure the aluminum content in ferroboron using
EDTA titration method:
--- Part 5: Chemical analysis of ferroboron - Determination of sulfur content by chromatographic separation and barium sulfate gravimetric method: The purpose is to measure the sulfur content of ferroboron:
The content was determined by the barium sulfate gravimetric method using chromatography:
--- Part 6: Chemical analysis method for ferroboron - Determination of phosphorus content by antimony phosphomolybdenum blue photometric method: The purpose is to measure the phosphorus content in ferroboron:
Using antimony phosphomolybdenum blue photometry:
--- Part 7: Determination of sulfur content in ferroboron - Infrared absorption method: The purpose is to measure the sulfur content in ferroboron using infrared
Absorption method:
