ISO 14405-2:2011说明了对不是线性尺寸的尺寸的几何公差的使用，以避免使用这些尺寸上的±公差造成的歧义。除了尺寸特征之外，线性和角度尺寸均被覆盖。 尺寸公差可以通过±公差或几何公差来表示。 通过使用±线性尺寸以外的尺寸误差引起的模糊度在附录中进行了说明

ISO 14405-2:2011 illustrates the use of geometrical tolerancing for dimensions that are not linear sizes to avoid the ambiguity that the use of ± tolerances on these dimensions causes. Both linear and angular dimensions, except size of features of size, are covered. Dimensional tolerancing can be indicated by ± tolerancing or geometrical tolerancing. The ambiguity caused by using ± tolerances for dimensions other than linear sizes is explained in an informative annex.
