TSG R0004-2009 Safety Technical Regulations of Special Equipmems
In May 2007, the Special Equipment Safety Supervision Administration (abbreviated as
SESA hereinafter) of the General Administration of Quality Supervision, Inspection and
Quarantine (abbreviated as AQSIQ, hereinafter) established the project plan to revise
"Supervision Regulation on Safety Technology for Stationary Pressure Vessel" (abbreviated as
SRSTSPV, hereinafter). In September 2007, the Technical Regulation Division of China
Special Equipment Inspection and Research Institute (abbreviated as CSEI, hereinafter)
established a Working Group of the formulation (revision) and held the first meeting in
Beijing. On the meeting the Working Group discussed principles, important contents, key
issues and outlines. for formulating (revising) the SRSTSPV, concretely assigned
responsibilities of the drafting work, and set down a time table for the outline. In November
2007, the Working Group held the second meeting in Beijing and announced the exposure
draft of the SRSTSPV as results of discussion. SESA issued Announcement [2008] No. I 0 to
request comments from primary sectors, relevant departments and organizations, experts and
citizens. In May 2008, the Working Group held the third meeting in Suzhou, Jiangsu Province
and delivered the regulation draft incorporating the collected opinions. During the formulation
(revision), SESA also held several seminars to discuss maj.or issues of the formulation
(revision) for the SRSTSPV, and commissioned CSEI and China Association of Special
Equipment Inspection to organize two symposiums in January 2008 and July 2008
respectively to discuss the revision of the non-destructive examination in the SRSTSPV. In
August 2008, SESA submitted the revised draft to the Special Equipment Safety Technology
Committee of AQSIQ for deliberation. By integrating the valuable suggestions and corrunents,
the Working Group further modified the draft and came up with the new revision for approval.
In October 2008, the draft for approval of the SRSTSPV was submitted to WTO/TBT for
notification by AQSIQ. In April 2009, the Working Group responded to the advisory opinions
from the WTO/TBT, held a meeting to finalize the SRSTSPV in Beijing in May 2009, and
determined the final version for approval of the SRSTSPV. On August 31, 2009, the
SRSTSPV was approved and published by AQSIQ.
The fundamental principles of the revision of the SRSTSPV include the following.
(I) Transform the SRSTSPV into a safety technical regulation of special equipments
TSG R0004-2009 Safety Technical Regulacions of Special Equipments
equipment" that were not subjected to the safety supervision in the original SRSTSPV.
Meanwhile, the original version (1999) of "Supervision Regulation on Safety Technology for
Pressure Vessef' is converted to "Supervision Regulation on Sqfety Technology for Stationary
Pressure Vessel". In addition, "Supervision Regulation on Safety Technology for
Transportable Pressure Vessel" is formulated othexwise, and some recently issued supervision
regulations regarding safety technology are temporarily retained that including pressure
vessels such as super-high pressure vessels, simple pressure vessels, non-metallic pressure
vessels, and so on. Some provisions with limitation are adjusted with some flexibility so as to
facilitate the application of new materials, new processes and new technologies. A few
unnecessary or outdated provisions, such as issues of the design pressure for liquefied gases,
nonferrous ID.etals, the expanding ratio of tubes, the re-examination requirements of materials,
product welded test coupons, and so on, are accordingly adjusted. The risk-based inspection
(RBI) technology, the Time of Flight Diffraction Technique (TOFD), and the evaluation
methods for defects are introduced based on scientific and technological researches, and
scientific and technological achievements. Unnecessary superfine data sheets are adjusted
(deleted) and the product data sheet of pressure vessels is increased. The raised requirement
of informational process laid down the foundations for the future information-based

Supervision Regulations on Safety Technology
for Stationary Pressure Vessels
1 General Requirement
1.1 Purpose
In order to ensure the safe operation of stationary pressure vessels, protect the safety of
human life and property, and promote the development of national economy, this Supervision
Regulations on Safety Technology for Stationary Pressure Vessels (abbreviated Regulation,
hereinafter) is established in accordance with "Regulations on Satety Supervision of Special
1.2 Stationary pressure vessels
Stationary pressure vessels refer to pressure vessels installed and operated at fixed
locations (hereinafter referred to as pressure vessels, see Note 1-1) .
Note 1-1. Pressure vessels to be moved and/or used within the certain scope of the facility or plant
field fo r a particular purpose, as well as air tanks in transportable air compressor units are jurisdicted by
this regulation.
l .3 Applicable scope
This Regulation is applicable to stationary pressure vessels in conformity with all of the
following conditions as a whole.
