In July 2013, the Special Equipment Safety Supervision Bureau (hereinafter referred to as "SESSB") of the State Administration for Market Supervision issued the project approval assignment for "Supervision Regulation on Safety Technology for Stationary Pressure Vessel" (hereinafter referred to as "the Regulation") and asked to form the general regulation for stationary pressure vessels on the basis of the former seven regulations, i.e., "Supervision Regulation on Safety Technology for Stationary Pressure Vessel" (TSG R0004-2009), "Nonmetal Pressure Vessels Safety and Technical Supervision Regulation" (TSG R0001-2004), "Super-high Pressure Vessel Safety and Technical Supervision Regulation" (TSG R0002-2005), "Simple Pressure Vessels Safety and Technical Regulations" (TSG R0003-2007), "Pressure Vessel Service Administration Regulation" (TSG R5002-2013), "Pressure Vessels Periodical Inspection Regulation" (TSG R7001-2013) and "Regulation on Supervision Inspection for Pressure Vessel" (TSG R7004-2013). In August 2013, the Technical Regulation Department of China Special Equipment Inspection and Research Institute (hereinafter referred to as "CSEI") organized the relevant experts to form the drafting group and the professional groups of materials, nonmetal pressure vessels and super-high pressure vessels, etc., formulated the drafting work program of "the Regulation", determined the development principle, key contents, main problems and structural (chapters and sections) frame of "the Regulation", and made specific work division in term of drafting and prepared the drafting work schedule. The drafting group and the professional groups separately carried out investigation and drafting work, convened workshops for many times and formed the "the Regulation" (draft). In December 2013, the drafting group convened the plenary meeting in Beijing and formed the "the Regulation" (exposure draft) through discussion and modification. In February 2014, SESSB solicited opinions from the grass-roots departments, organizations concerned, experts and citizens with Document ZhiJianTehan [2014] No.5. In June 2014, the drafting group convened the second meeting, studied and discussed the opinions solicited on the meeting and formed "the Regulation" (draft for examination). In July 2014, SESSB submitted to the draft for examination to the Special Equipment Safety Technology Committee, the State Administration for Market Supervision for deliberation; the drafting group convened working meeting in September, October and November 2014 separately, studied and discussed the deliberations on the meetings and formed "the Regulation" (draft for approval). In August 2015, the State Administration for Market Supervision informed WTO/TBT of "the Regulation" (draft for approval). In November 2015, the drafting group replied to the advisory opinions of WTO/TBT. On February 22, 2016, the State Administration for Market Supervision approved and issued "the Regulation".
The basic development principles of "the Regulation" are as follows:
1. Merge the former seven regulations for pressure vessels and straighten them out in terms of logical relation, unify and further explicitly define the basic safety requirements, and form the general regulation for stationary pressure vessels.
2. Adjust the applicable scope and unify the classification of stationary pressure vessels according to the Catalogue of Special Equipment.
3. Adjust the administrative licensing requirements relevant to each procedure according to the reformation of administrative licensing.
4. Sort out the relevant documents for safety supervision on pressure vessels issued by the State Administration for Market Supervision in recent years, summarize the specific problems existing in publicity and implementation of "Supervision Regulation on Safety Technology for Stationary Pressure Vessel", collect the on-line advisory opinions, supplement corresponding contents, and focus on settling the currently existing prominent problems.
5. Expand the material scope, focus on settling the technical requirements (safety factor, chemical composition, mechanical properties and applicable scope) of the materials for cast steel and cast iron pressure vessels, and add the technical requirements of high strength steel materials for unwelded cylindrical vessels.
6. Describe by chapters according to the procedures of stationary pressure vessels, make the boundary of each procedure be as clear as possible, and make clear the corresponding entity responsibilities (e.g., make clear the medium, pressure and temperature of pressure test, and the non-destructive testing method, proportion, heat treatment and other technical requirements will be proposed by the designer and be included in the corresponding design chapters and sections).
7. Straighten out the relation among laws, rules and standards, integrate and compact the basic safety requirements of stationary pressure vessels, and specify some detailed technical contents in corresponding product standards.
