5.3Visual distance (see table 1)
Could you not see the irregularity by visual distance (see table 1) the part is good.
5.4Duration of visual observation for simple parts (workstations)
Table 1
5.5Tools
For determination of relevant dimensions in visual failure, an appropriate facility has to be used. Alternatively it can be a stencil or a Lence with scale.The given facilities are exact enough for the operation and are allowed for general use. Before using it, you have to check if the fitness is reduced due to soilingb or demage. In such cases the use is not allowed.5.5.1Tools stencil
Application: The stencil is positioned on to the defect to measure ist size.Picture 1:
