Foreword
In April 2008, the Special Equipment Safety Supervision Bureau (hereinafter
referred to as the Special Equipment Bureau) of the General Administration of
Quality Supervision, Inspection and Quarantine (hereinafter referred to as the
AQSIQ) issued the task book for drafting the “Supervision regulation on safety
technology for gas cylinder (hereinafter referred to as “Regulation”)” to the
China Special Equipment Inspection and Research Institute (hereinafter
referred to as the China Special Inspection Institute). In May 2008, the China
Special Inspection Institute organized relevant experts to set up a drafting group
and held the first working meeting in Beijing, to discuss the principles, key
contents, main issues, structure (chapter) framework for the drafting of the
Regulations, made specific work division on the drafting work, established a
time schedule for the drafting work. In October 2008 and March 2009, the
drafting group held the second and third drafting work meetings in Beijing, to
discuss and revise and form the draft of “Regulation” for comments. In
September 2010, the drafting group held the fourth working meeting in Zhejiang
Shangyu, to make corresponding modifications of the draft of “Regulation” for
comments. In April 2011, after reviewing the draft for comments, the Special
Equipment Bureau solicited for comments online in the form of ZJTH [2011]
No.19 documents. In September 2011, according to the solicited opinions, the
drafting group held its fifth working meeting in Beijing, formed a revision opinion
on the draft of “Regulation” for comments. In December 2011, the drafting group
revised and formed the “Regulation” for review in accordance with the spirit of
the fifth work meeting. In May 2012, the Special Equipment Bureau submitted
the draft for review to the Special Equipment Safety Technical Committee of the
General Administration of Quality Supervision, Inspection and Quarantine for
review. The drafting group revised the draft to form a draft for approval
according to the review opinions. On September 5, 2014, the “Regulation” was
approved by the General Administration of Quality Supervision, Inspection and
Quarantine for release.
The basic principles of the drafting of this “Regulation” are that, according to
the “Law on Safety of Special Equipment” and “Provisions on Safety
Supervision of Special Equipment”, on the basis of fully absorbing and
combining the actual situation and experience of safety supervision of gas
cylinder for many years, in order to strengthen the safety supervision of gas
cylinder, ensuring the safe use of gas cylinders, promoting the development of
the national economy, protecting the safety of people and property, it
establishes specific requirements for the safety supervision of gas cylinder in
such links as material, design, manufacturing, gas cylinder’s accessories, filling
and use, periodic inspections.

Supervision regulation on
safety technology for gas cylinder
1 General
1.1 Purpose
In order to ensure the safety of gas cylinders, protect the safety of people and
property, promote the development of the national economy, this Regulation is
hereby formulated in accordance with the “Law on Safety of Special Equipment”
and “Provisions on Safety Supervision of Special Equipment”.
1.2 Scope of application
This procedure is applicable to the seamless gas cylinders, welded gas
cylinders, welded insulated gas cylinders, wound gas cylinders, gas cylinders
filled with fillers, gas cylinder accessories which is used at a normal ambient
temperature of (-40°C ~ 60°C, note 1-1), nominal volume of 0.4 L ~ 3000 L,
nominal working pressure of 0.2 MPa ~ 35 MPa (gauge pressure, the same
below), has a product of pressure multiplied by volume of more than or equal
to 1.0 MPa • L, contains compressed gas, high (low) pressure liquefied gas,
low-temperature liquefied gas, dissolved gas, adsorbed gas, liquid with a
normal boiling point of equal to or less than 60°C, mixed gas (two or more than
two kinds of gases).
The materials, design, manufacture of gas cylinders for fire extinguishers, large-
volume gas cylinders used for long tube trailers and tube bundle containers, or
large-volume gas cylinders for electronic gas are in accordance with this
Regulation.
The main gas cylinder varieties, variety codes, corresponding product
standards as covered by this Regulation are as shown in Appendix A.
Note 1-1: The ambient temperature range of gas cylinders for vehicles and fire
extinguishers shall be in accordance with the relevant standards.
1.3 Special provisions on the scope of application
The cylinder accessories in the scope of application in clause 1.2 of this
Regulation shall, in addition to complying with this Regulation, also comply with
the provisions of the “Gas cylinder appurtenances safety and technical
supervision regulation” (TSG RF001). The gas cylinders for vehicles (Note 1-2)
shall, in addition to complying with this Regulation, also comply with the
provisions of the “Gas cylinders safety and technical supervision regulation for
vehicles” (TSG R0009).
Note 1-2: The gas cylinders for vehicles as covered in this Regulation refer to the gas
cylinders used to contain vehicle fuels (such as compressed natural gas, liquefied
natural gas, hydrogen, liquefied petroleum gas, liquefied dimethyl ether, etc.).
1.4 Scope of non-application
This Regulation does not apply to gas cylinders for fire extinguishers that are
only subjected to transient pressure during firefighting and are not subject to
pressure during storage, fixed-use cylinder-type pressure vessels, gas
cylinders for military equipment, nuclear facilities, aerospace vehicles, railway
locomotives, offshore installations and ships, special equipment for civil airports.

(2) The supervisory inspection agency will inspect the safety performance of
the temporarily imported gas cylinders and issue the inspection report. For
the gas cylinders which require repeated entry but cannot be tested for
safety performance at the time of entry, they shall, after the gas in the
cylinder is exhausted, be subjected to the inspection of safety
performance. For gas cylinders that cannot be internally inspected due to
gas characteristics, etc., the importing organization shall provide the valid
inspection certificate as issued by the inspection agency of the country (or
region) where the gas cylinder’s property rights are located, and only after
confirmation by the supervisory inspection agency, it can only perform the
appearance inspection and determination of wall thickness, with
corresponding inspection reports. Gas cylinders that fail in the inspection
(or appearance inspection, determination of wall thickness) shall not be
used in China;
