摘要

To discuss both nonparametric and parametric methods of setting tolerance limits, from which it can be determined with a specified confidence what percentage of a product made under commercial conditions may be expected to have a quality falling between the tolerance limits. In quality control, studying tolerance limits is an important topic. Tolerance limits provide boundaries to ensure that a specific proportion of the population at a desired confidence level. Product quality has become highly important in today's competitive world, and the use of tolerance limits has become a common method of specifying the quality of a manufactured product. Tolerance limits are often desirable as a supplement to quality control and/or reliability procedures. Tolerance limits are also practical and useful in various unconventional areas where they are not usually applied, such as warranties, failure free operational time (hours) of complex machines used in large machine shops, and availability of equipment.
