![]() ![]() Experimental investigation is very useful to investigate the effects of tolerances: Design of experiments, formal engineering evaluations, etc.Ī good set of engineering tolerances in a specification, by itself, does not imply that compliance with those tolerances will be achieved. This can be by the use of scientific principles, engineering knowledge, and professional experience. Considerations when setting tolerancesĪ primary concern is to determine how wide the tolerances may be without affecting other factors or the outcome of a process. A variation beyond the tolerance (for example, a temperature that is too hot or too cold) is said to be noncompliant, rejected, or exceeding the tolerance. ![]() This is just one of the 8 defined ranges (30–120 mm).ĭimensions, properties, or conditions may have some variation without significantly affecting functioning of systems, machines, structures, etc. This is just one example for linear tolerances for a 100 mm value. Example for the DIN ISO 2768-2 tolerance table.
