Sink marks at the base of ribs and reinforcements are only permissible if they do not adversely affect the function, appearance, and/or assembly of the parts. The finished parts must allow for trouble-free installation.PackagingFinished parts must be packed in a way that allows air circulation. For delivery in large packaging units (cardboard boxes, pallets), the finished parts must be stacked or arranged so that air circula‐tion is possible.Marking as per VDA 260> POM <ConditioningPrior to testing, the specimens must be conditioned in the ISO 554-23/50 standard climate for at least 24 h.Evaluation of the measurement resultsThe required numerical values apply to each individual measurement.MaterialSee section 5.2.Polyoxymethylene (POM) homopolymer or, alternatively, copolymer.ColorAs per drawing and/or release.PropertySee table 1.3.1.13.1.23.2 3.33.43.53.64Page 3TL 52476: 2014-04 Table 1Page 4TL 52476: 2014-04Notes on testing Emission behaviorIf the test results do not comply with the requirements of VW 50180, the parts must be tempered until the limit values are met.

在零件生产现场, 通过检具实现对零件的在线检测,为此需要将零件准确地安装于检具上, 然后通过目测,或测量表,或卡尺对零件型面, ,也可以借对零件上不同性质的孔及零件与零件之间的联接位置进行目检，从而保证在试生产及起步生产时实现零件质量状态的快速判断。
在此情况下，通过目检或测量可以判断: 零件轮廓大小CAD/CAM直接。
对于零件上的某些极其重要的，还能利用检具进行数值检测。
通常不能借检具直接获得零件基于车身坐标系统精确的坐标值, 而是将零件置于检具上通过三坐标测量机测量方才获得。
现代检具的结构在设计时同时考虑其可以作为测量支架使用。
但是当检具的在线检查，应首先满足检具的在线检查。
