　　A few days ago,the National Legal Metrology and Management Metrology Technical Committee issued a draft of"Rules for Measuring and Testing Energy Efficiency of Computer Displays"for comments,and asked members and relevant units for comments.

 

　　節約資源是我國的一項基本國策，為節約能源，《中華人民共和國節約能源法》和《能源效率標識管理辦法》明確規定國家對使用面廣的用能產(chǎn)品，實(shí)行能源效率標識管理。

 

　　Saving resources is a basic national policy of our country.In order to save energy,the Energy Conservation Law of the People's Republic of China and the Measures for the Management of Energy Efficiency Marking clearly stipulate that the State shall implement energy efficiency marking management for widely used energy products.

 

　　計算機顯示器是一種人們日常工作、學(xué)習和生活不可或缺的顯示設備，也是一種用能產(chǎn)品。國家制定了GB 21520-2008《計算機顯示器能效限定值及能效等級》和CEL-014《計算機顯示器能源效率標識實(shí)施規則》，并于2009年3月1日開(kāi)始對其實(shí)施能效標識管理。與這兩個(gè)技術(shù)文件對應的JJF 1261.6-2012《計算機顯示器能源效率標識計量檢測規則》于2012年發(fā)布實(shí)施，該規則的發(fā)布實(shí)施為政府計量部門(mén)開(kāi)展計算機顯示器能源效率標識計量監督檢查提供了有力的技術(shù)支撐。

 

　　Computer display is an indispensable display device for people's daily work,study and life.It is also an energy product.The State has formulated GB 21520-2008"Computer Display Energy Efficiency Limitation Value and Energy Efficiency Level"and CEL-014"Implementation Rules for Computer Display Energy Efficiency Identification",and started to implement energy efficiency identification management on March 1,2009.JJF 1261.6-2012,which corresponds to the two technical documents,was issued and implemented in 2012.The promulgation and implementation of the rules provide a strong technical support for the government Metrology Department to carry out the monitoring and inspection of energy efficiency identification of computer monitors.

 

　　在2015年和2016年，國家分別發(fā)布了新版的GB 21520-2015《計算機顯示器能效限定值及能效等級》和CEL 014-2016《計算機顯示器能源效率標識實(shí)施規則》，并于2016年10月1日開(kāi)始實(shí)施。由于2015版標準與2008版標準相比，在顯示器的分類(lèi)、能效等級的劃分、能效參數要求及測試方法上變化較大，對JJF 1261.6-2012《計算機顯示器能源效率標識計量檢測規則》的修訂勢在必行，因為自2016年10月1日后，將無(wú)法依據JJF 1261.6-2012開(kāi)展對顯示器能效標識的計量監督檢查工作。

 

　　In 2015 and 2016,the state issued the new edition of GB 21520-2015"Computer Display Energy Efficiency Limitation Value and Energy Efficiency Level"and CEL 014-2016"Implementation Rules for Computer Display Energy Efficiency Identification",which were implemented on October 1,2016.Compared with the 2008 edition,the 2015 edition of the standard has great changes in the classification of monitors,the classification of energy efficiency levels,the requirements of energy efficiency parameters and testing methods,so it is imperative to revise the JJF 1261.6-2012"Measuring and Testing Rules for Energy Efficiency Identification of Computer Displays".Since October 1,2016,it will not be possible to monitor the energy efficiency of monitors according to JF 1261.6-2012.Supervise inspection work.

 

　　根據原國家質(zhì)檢總局計量技術(shù)法規制修訂任務(wù)的安排，江蘇省計量科學(xué)研究院受中國計量協(xié)會(huì )委托，作為主要起草單位負責牽頭修訂了《計算機顯示器能源效率計量檢測規則》，主要起草單位還有中國計量科學(xué)研究院，參加起草單位包括：福建省計量科學(xué)研究院，天津市計量監督檢測科學(xué)研究院，天津三星電子有限公司，華碩電腦(上海)有限公司。

 

　　According to the arrangement of the revision task of the metrological technical regulations of the former State Administration of Quality Supervision and Inspection,the Jiangsu Institute of Metrology,entrusted by the China Metrology Association,took the lead in revising the Rules for Measuring and Testing Energy Efficiency of Computer Displays as the main drafting unit.The main drafting units included the Chinese Academy of Metrology and Sciences,and the drafting units included the Fujian Academy of Metrology and Scienc Tianjin Institute of Measurement Supervision and Inspection,Tianjin Samsung Electronics Co.,Ltd.,Asus Computer(Shanghai)Co.,Ltd.
