12、9、12.66,01.74DIN16901:07.73修订与1973年6月版本对比，本标注修订内容如下：在表1中增加了模塑材料的数昼对表2进行了重新排版：首次添加了“概念”章节。注释本标准由FNK小组委员会501.1制定在精密工程使用公差时，本标准无法给出模塑材料与表2中公差等级的相互关系。因此在粘密工程应用公差等级时，供应商和客户需确定公差等级是否可以与使用材料想匹配。对大量模塑件测量的实际尺寸偏差呈现出正态分布，因此町按DIN55302对于测量结果做统计学的评估。表2中的公差仅仅是生产公差，而不是全部公差。这是考虑到实践过程中，后收缩和膨胀町能发生在任何情况卜发生，而没何方法可以对其评估。
