The second plenary session and working group meeting of iso/tc153 (valves) were held in France

from September 9 to 11, iso/tc 153 (valves) held its second plenary session in Paris, France, and its three working groups WG1 (driving devices and their connecting accessories), wg6 (ball valves) and wg7 (valves for chemical processes and related industries) held meetings at the same time

from September 9 to 11, the International Technical Committee for standardization iso/tc 153 (valves) held its second plenary session in Paris, France, and its three working groups WG1 (driving devices and their connecting accessories), wg6 (ball valves) and wg7 (valves for chemical processes and related industries) held meetings at the same time. More than 30 representatives from 11 countries including China, Germany, the United States, Japan, South Korea, Italy, the United Kingdom, France, Canada, Spain and Switzerland attended the meeting

the national valve Standardization Technical Committee organized a delegation to participate in the meeting. The head of the delegation was Huang Mingya, secretary general. A total of 6 members came from five units, including Hefei General Machinery Research Institute, Jiangsu Shentong Valve Co., Ltd., Shanghai nafosi Valve Co., Ltd., Teflon Group Co., Ltd. and Huangshan liangye Valve Co., Ltd

the main contents of the three working group meetings are as follows:

WG1 Working Group mainly discussed the standards of "ISO 5210 industrial valves - connecting accessories for multi turn valve actuators" and "ISO 5211 industrial valves - connecting accessories for partial turn valve actuators" which are being revised. These two standards are in the charge of Mr. Tobias Wasser of AUMA, Germany. Since these two standards were revised as early as 2012, the iso/tc153 Secretariat requested the WG1 working group to submit two standard drafts to the Secretariat before November 1, 2015, and directly solicit comments on the dis draft, otherwise the revision of the two standards will be cancelled

The wg6 Working Group mainly discussed iso/dis 7121 flanged steel ball valves for industrial use. The revision of this standard is mainly in the charge of Mr. David batreuther, the convener of the working group from the United States. The Chinese delegation put forward the opinions of reducing the diameter of socket welded valves and the judgment standard of casting defect grade on the surface of valve castings, which were unanimously recognized and adopted by the convener of the working group and the representatives attending the meeting

The wg7 Working Group mainly discussed the newly formulated national standard iso/np19240 industrial valves - partially rotary lined valves for chemical processes and related industries. After internal discussion of the working group, the standard title was revised to "industrial valves - chemical process and related industrial parts with strong scientific and technological strength, rotary and check lined metal valves"

2015 has been providing product services for new and old customers for a long time. In June, China took the lead in formally submitting a proposal document to the iso/tc153 Secretariat on the development of a new national standard for general requirements for electric actuators of industrial valves. In August 2015, South Korea also submitted an application to the Secretariat for the development of new international standards for valve electric devices. At the WG1 working group and plenary meeting, the Chinese delegation introduced in detail the background, process and scope of the new national standard proposal. After discussing and questioning the professional instruments for safety performance testing, according to the proposal of the Chinese delegation, an agreement was reached at the iso/tc153 plenary meeting. The standard scope of the general requirements for electric devices of industrial valves prepared by WG1 working group will include the general requirements for electric devices of switching and control valves, mainly including the requirements for design, test, marking and documentation. The standard will be drafted by China

the 2nd iso/tc153 plenary meeting was presided over by President exandre PopA. Secretary General len cross submitted the 2nd Secretariat work report and other documents to the general assembly. The relevant working groups reported on the work of this group. The Secretariat introduced the establishment of liaison between this Technical Committee and other technical committees, and adjusted the subordinate relevant working groups.
