dimensions for linear gages are usually given in inches, cm, mm, or 10 mm. angular dimensions are usually expressed in degrees, minutes, or seconds. however, some standards may give the angular dimensions in degrees and minutes, or both degrees and minutes. most standards specify tolerances for the position of parts as linear and as angular.

iso 13485 (this standard is broken up into nine parts) deals with the requirements and processes for the implementation of medical devices. iso 13485 sets out how to ensure that devices that have the potential to affect human health are safe and effective. an essential requirement of iso 13485 is the validation of the system, device, or service to ensure that it satisfies the regulatory requirements for medical devices. it is the responsibility of the manufacturer to ensure that the product meets the requirements of medical devices under the general principles of quality management system.

in general, the intent of the iso 2768 standard is to define general tolerances that are used for dimension of parts in manufacturing. the intent of the standard is to establish general tolerances in three tolerance classes. it is a high-level specification, and is not intended to serve as a precise dimensional control in any particular industrial application. the intent of the standard is to provide a framework for defining the required tolerances.

a tolerance of +/-.02 is a high level of precision. a tolerance of +/-.01 is a medium level of precision.05 is a low level of precision. for an iso 2768 compliant part, a tolerances class would be assigned based on the geometric and functional needs of the application.

q. can a tolerance range be based on a tolerance. a tolerance should be specified separately to a given feature and not associated with that feature. a tolerance is a range of values for a given feature. in this context, it is a measure of tolerability and relates to how much a feature can move within the tolerances with respect to its neighbors. the ranges of actual and permitted values may be the same or they may be different, depending on the characteristics of the feature.
d. if it is necessary to use the tolerances of one feature to define the tolerances of another feature, use the two concepts mentioned above — joint tolerances and general tolerances. joint tolerances are used to define both joint limits and joint tolerances. joint limits are features with which another feature is joined. joint tolerances can only be associated with joint limits and define the tolerances of those features within the joint. for example, if the width of a machined joint feature is specified to be within specified tolerance limits relative to the width of a drill hole, that specification could also be used to limit the diameter of a drill hole in which to make the joint. general tolerances are used to indicate the dimension tolerances of features that are not joint limits. this should not be confused with general machining tolerance which are used to indicate the actual machining tolerances of a feature and which can be much higher than the tolerance range selected for the nominal dimension. the two concepts are somewhat loosely defined, since in general dimensional specifications usually are expressed as joint limits relative to adjacent features and outside a joint the part tolerances are usually expressed as general tolerances. further, a dimension specification can sometimes be an actual joint limit relative to a neighboring feature (such as the diameter of a hole bored in a finished dimension) or a joint relative to one feature that connects with another feature. for example, when a small hole is drilled in a larger hole, the hole diameter can be within general or even joint tolerances relative to the hole, but it is still limited in its tolerance range relative to the hole, since the inner hole diameter must be less than the hole diameter.
