7、AG2、AG3、AG5、AG6的“参照ISO230–1和备注”中的“此垂直度偏差也能从检验G×和G××中推出”等文字，因采用直接检验更能反映精度的实际情况，被取消。——4.2线性运动的角度偏差中G6的c)在Z–X水平面内（倾斜）的检验，因其检验方法不能确切和方便地达到该检验项目的要求，且该检验项目可通过G3的a)项检验受到控制，故G6的c)项取消。本标准是加工中心检验条件系列标准之一，该系列标准包括以下13个部分，它们可以同时或单独使用：第1部分：卧式和带附加主轴头机床几何精度检验（水平Z轴）第2部分：立式加工中心几何精度检验第3部分：带水平主回

8、转轴的整体万能主轴头机床几何精度检验（垂直Z轴）（待制订）第4部分：线性和回转轴线的定位精度和重复定位精度检验第5部分：工件夹持托板的定
