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.
