This part of BS 1916 gives guidance on tolerances, limits and fits for large diameters (19.69 in to 125 in).

In many industries, components in large sizes are made to interchangeable as well as to matched fits. There are many practical problems, however, in achieving interchangeable manufacture in large diameters, due mainly to difficulties of measurement.

Clause 4 and Clause 5 in Section 1 discuss the known difficulties which might be encountered and draw attention to those tolerances and fits where the greater difficulties might be expected to arise. Section 2 puts forward tables of tolerances, deviations and limits for shafts and holes.

It is strongly emphasized that these should be regarded as recommendations intended for trial purposes. They are published in the expectation that experience in their use will enable them to be confirmed or modified, and will help to bring to light deficiencies in measuring techniques.

An explanation of the system to which this standard forms an extension is contained in BS 1916‑1.
