Foreword
GB/T 3634 “Hydrogen” is divided into the following two parts
- Part 1. Industrial hydrogen;
- Part 2. Pure hydrogen, high pure hydrogen and ultrapure hydrogen.
This part is part 1 of GB/T 3634.
This part replaces GB/T 3634-1995 “Industrial hydrogen”.
As compared with GB/T 3634-1995, the main changes of this part are as
follows.
- In the Chapter of scope, ADD the hydrogen production methods and
industrial hydrogen application scopes (Chapter 1 of this version);
- ADD the relevant normative references (Chapter 2 of this version);
- IMPROVE the requirements for nitrogen content and argon content
(Chapter 3 of the 1995 version; Chapter 3 of this version);
- ADD the inspection rules for containerized products (SEE clause 4.1.1 and
4.1.2 of this version);
- MODIFY the test method; ADD the method of determining oxygen and
oxygen components (clause 4.3 of 1995 version; Appendix A of this
version);
- INCLUDE the chlorine and alkali measurement device schematics into the
normative appendix (Figure 2 of 1995 version; Appendix B of this version);
- INCLUDE the hydrogen volume calculation into the informative appendix
(clause 6.6 and Appendix A of 1995 version; Appendix C of this version).
Appendix A and Appendix B of this part are normative, AND Appendix C is an
informative appendix.

Hydrogen – Part 1. Industrial hydrogen
1 Scope
This part specifies the requirements, test methods, packaging and marking,
storage, transportation and safety requirements for industrial hydrogen.
This part is suitable for the hydrogen contained in cylinder, containerized, and
pipeline delivery which is made from chemical cracking, electrolysis,
adsorption, membrane separation, hydrogenation and other methods. It is
mainly used for such industries as the manufacturing, metal smelting, cutting,
and welding of petroleum, food, fine chemicals, glass and artificial gem.
Molecular formula. H2
Relative molecular mass. 2.01588 (in accordance with the 2001 International
Relative Atomic Scale)

diameter of 3 mm, containing a 13X molecular sieve of 0.25 mm ~ 0.40 mm; or
other equivalent column. The column is hydrogenated for activation at 180 ° C
~ 220 ° C for about 3 h at a flow rate of 60 mL/min ~ 80 mL/min. The column is
used at room temperature.
A.1.3.3 Deoxygenated column. stainless steel tube with a length of 3 m and an
inner diameter of 3 mm, fitted with a 401 deoxidizer of 0.4 mm ~ 0.8 mm. The
use and activation of the deoxidizer is carried out in accordance with its
instructions.
A.1.4 Gas standard samples
The certified gas standard sample having a component content similar with the
corresponding component content in the sample gas, AND its balancing gas is

A.1.5 Determination
After the instrument is stable, MAKE determination in accordance with the
instrument manual. MAKE parallel determination of the gas standard sample
and sample gas for at least two times; RECORD the peak area (or peak
height), until the relative deviation of the adjacent two measurements is not
more than 5 × 10-2; TAKE the average.
A.1.6 Result processing
USE the peak area (or peak height) for quantification; USE the external
