Recently, the **General Administration of Quality Supervision, Inspection and Quarantine approved the release of 357 standards**, of which 235 are newly formulated standards and 86 are international standards. The editor has extracted several standard details related to our instrumentation industry for your reference. Standard Number Standard Name Replacement Standard Number Date of Implementation GB/T 2903-2015 Copper–copper-nickel (constantan) thermocouple wires GB/T 2903-1998 2015-12-01 GB/T 4994-2015 Iron–copper-nickel (constantan) thermocouple wires GB/T 4994-1998 2015-12-01 GB/T 9138-2015 Rebound tester GB/T 9138-1988 2015-12-01 GB/T 12220-2015 Marking for industrial valves GB/T 12220-1989 2016-02-01 GB/T 17615-2015 Nickel-chromium-silicon–nickel-silicon-magnesium thermocouple wires GB/T 17615-1998 2015-12-01 GB/T 19786-2015 Test methods for wooden packaging containers GB/T 19786-2005 2016-01-01 GB/T 19788-2015 Test methods for honeycomb cardboard boxes GB/T 19788-2005 2016-01-01 GB/T 30966.5-2015 Wind turbines – Communication in wind farm monitoring systems – Part 5: Conformance testing 2016-02-01 GB/T 30966.6-2015 Wind turbines – Communication in wind farm monitoring systems – Part 6: Logical node types and data types for condition monitoring 2016-02-01 GB/T 31423-2015 Guidelines for performance acceptance of oxygen bomb calorimeters 2015-07-01 GB/T 31424-2015 Method for determining ash viscosity 2015-07-01 GB/T 31425-2015 Technical requirements for coulometric sulfur analyzers 2015-07-01 GB/T 31427-2015 Technical requirements for ash fusion testers 2015-07-01 GB/T 31429-2015 Guidelines for quality control in coal laboratory testing 2015-07-01 GB/T 31473-2015 Halogen gas detectors 2016-01-01 It is understood that the standards for copper–copper-nickel (constantan) thermocouple wires, iron–copper-nickel (constantan) thermocouple wires, and nickel-chromium-silicon–nickel-silicon-magnesium thermocouple wires were jointly drafted by enterprises such as Chongqing Materials Research Institute Co., Ltd., the Metal Functional Materials Branch of Chongqing CHUANYI Automation Co., Ltd., Chongqing CHUANYI No. 17 Factory Co., Ltd., Jiangsu Huaxin Alloy Co., Ltd., and Anhui Land Group Co., Ltd. In addition, Changsha Kaiyuan Instrument Co., Ltd. participated in drafting the standard \"Technical Requirements for Coulombic Sulfur Analyzers\". http://www.tcwdyb.com/upload/2018-01/27/QQtupian20180127081222.png
The introduction of these standards can regulate some enterprises in the current market, addressing issues such as arbitrarily reducing the cross-sectional area of filaments and passing inferior products off as good ones, thereby preventing unfair competition that harms consumers’ interests. However, this will not have an effect on some companies that use old spools to pass them off as good ones; it is hoped that appropriate measures will be introduced to regulate market behavior.
