盘装仪表的尺寸现在已成为国际标准化的一个课题了。国际电工委员会(IEC)的第13技术委员会(TC_(13),研究测量仪表)已提交一文件给各国的国家委员会,由它们按“六月原则”进行审批。第65技术委员会(TC_(65),研究工业流程测量和控制)的第8工作组也在致力于准备一个标准草案。本文就仪表尺寸的一些基本思想作一概述,以说明TC_(13)和TC_(65)在规定尺寸的争论中的一致点。这些标准有重要的经济意义,故必须对各种情况进行仔细彻底的讨论。西德盘装仪表尺寸的国家标准化工作早在30年前就已经开始了。起初,标准的范围只涉
The size of the instrument has now become a subject of international standardization. International Electrotechnical Commission (IEC) No. 13 Technical Committee (TC_ (13), research measuring instruments) has submitted a document to national committees, by them according to “June principle” for approval. Working Group 8 of Technical Committee 65 (TC_ (65), Researching Industrial Process Measurement and Control) is also working on the preparation of a draft standard. This article gives an overview of some of the basic ideas of meter size to illustrate the consistent point in the debate over the size of TC_ (13) and TC_ (65). These standards have important economic implications and must be discussed thoroughly and thoroughly in all circumstances. The national standardization of the size of the measuring instrument in the West Germany plateau started 30 years ago. Initially, the scope of the standard only involved
