適用范圍：This part of BS 1916 gives guidance on tolerances, limits and fits forlarge diameters (19.69 in to 125 in).In many industries, components in large sizes are made tointerchangeable as well as to matched fits. There are many practicalproblems, however, in achieving interchangeable manufacture inlarge diameters, due mainly to difficulties of measurement.Clause 4 and Clause 5 in Section 1 discuss the known difficulties whichmight be encountered and draw attention to those tolerances and fitswhere the greater difficulties might be expected to arise. Section 2 putsforward tables of tolerances, deviations and limits for shafts and holes.It is strongly emphasized that these should be regarded asrecommendations intended for trial purposes. They are published inthe expectation that experience in their use will enable them to beconfirmed or modified, and will help to bring to light deficiencies inmeasuring techniques.An explanation of the system to which this standard forms an extensionis contained in BS 1916-1.
