国家标准GB 4201-84《通用卧式平衡机校验法》和国家标准《立式平衡机校验法》(报批稿)第6章“不平衡量减少率的校验”的第6.1.3、6.1.4和6.1.5款规定了绘制许用圆图的方法和步骤。第6.2.4和6.2.5两条说明了许用圆图的应用。这两个国家标准中所规定的绘制许用圆图的方法及其使用是等效采用了国际标准ISO 2953-1985《平衡机的描述与评定》。在贯彻和执行这两个国家标准时发现,实际使用这种作图方法和许用圆图时有两个缺点。一是作图方法复杂,不能充分使
National Standard GB 4201-84 “universal horizontal balancing machine calibration method” and the national standard “vertical balancing machine calibration method” (for draft) Chapter 6 “Unbalance reduction rate of verification” of the first 6.1.3, Subclauses 6.1.4 and 6.1.5 provide methods and procedures for drawing a chart of permissibility. Paragraphs 6.2.4 and 6.2.5 illustrate the use of permissive circular diagrams. The method of drawing a chart of permissive rounds and its use as specified in these two national standards is equivalent to that of the international standard ISO 2953-1985, “Description and assessment of balancing machines”. In implementing and implementing these two national standards, it was found that there are two shortcomings in the actual use of such mapping methods and permitting circular diagrams. First, the complexity of mapping methods can not be fully used
