DIN 1686 - Standard for Rough Casting General Tolerance
What standard can be used for the rough casting dimensional tolerance for iron, steel and aluminum castings? and how can find a free downloaded DIN 1686 standard?
We recommend the DIN 1686 standard for the rough casting general tolerance. Please see the following table. We believed this standard is widely using by the purchasers and suppliers. It is a good reference for the unspecified casting tolerance.
However, we still think we should not take it as an absolutely inspection standard. For some positions, if they do not need as accurate as this standard requirements, we should enlarge the tolerance. Likewise, for the positions, we should take them more seriously in case of unnecessary trouble caused on your clients. All in all, you should take this standard as a useful reference, not an accurate inspection standard.
