一、修订意义JJG343-1996《光滑极限量规》检定规程(以下简称“旧规程”)制定已有10余年,随着光滑极限量规加工工艺和检测手段的不断提高,旧规程无论是在技术要求上还是在检测方法上都已不能满足要求。且在此过程中光滑极限量规国家标准GB/T1957-2006《光滑极限量规%技术条件》和GB/T1800.1-2009《产品几何技术规范(GPS)极限与配合第一部分:公差、偏差和配合的基础》已重新修订,本着“力求完整、科学合理”的原则,兼顾操作及实施的可行性,我们根据国质检办量函
First, the revised meaning JJG343-1996 “smooth limit gauge” verification procedures (hereinafter referred to as “old procedure ”) has been developed for more than 10 years, with the smooth limit gauge processing technology and testing methods continue to improve, both in the old rules of technology Requirements or testing methods can no longer meet the requirements. And in the process of the smooth limit gauge national standard GB / T1957-2006 “smooth limit gauge% of technical conditions” and GB / T1800.1-2009 “Product Geometry (GPS) limit and cooperation Part I: tolerance, deviation and coordination Basis ”has been revised, in line with “ strive for complete, scientific and reasonable ”principle, taking into account the feasibility of operation and implementation, we check according to the quality of the country letter
