国家标准《表面形状和位置公差》(GB1182-74、GB1183-75、GB1184-75)的宣传贯彻工作已开展一年了。在各省、市、自治区和各有关部标准主管部门的领导和关怀下进行了大量的工作,已经有一批试点厂在产品中贯彻。在宣贯过程中,我们收到不少反映和意见。现将其中一部分问题分成四个方面进行说明和解释。其中第四个问题是对标准的补充和说明。如合适,可在生产中应用;如不妥,请继续提出意见,以便进一步探讨,更好地解决。
National standard “surface shape and position tolerance” (GB1182-74, GB1183-75, GB1184-75) propaganda and implementation work has been carried out for one year. A great deal of work has been done under the leadership and caring of the provinces, municipalities and autonomous regions and the competent departments under the relevant departments and standards. A number of pilot plants have been implemented in the products. In the publicizing process, we have received many reflections and opinions. Now part of the problem is divided into four aspects to explain and explain. The fourth issue is to supplement and explain the standard. If appropriate, can be used in production; if not properly, please continue to make comments in order to further explore and better solve.
