Specification limits establish the acceptable values and tolerances for collection elements. You can set specification limits for collection elements of any collection element or datatype; however, they normally are associated with variable collection elements that represent numeric measurements such as length, weight, and temperature. Specification limits include a target value (the preferred value) and three sets of upper and lower range limits, which can be changed without
restriction.

You create specification elements by adding collection elements to your specifications. Collection element specification limits are defaulted to these specification elements. For example, if you create a specification element by adding the Frequency collection element to a specification, the target value of 2000, and lower and upper user–defined, specification, and reasonable range limits — 1800–2200, 1720–2080, and 1600–2400 respectively — are defaulted to the specification element.

Attention: If you are defining specification limits for numeric collection elements, the decimal precision of the collection element controls the decimal precision of the specification limits. For example, if the decimal precision of the collection element is 3, you can define specification limits of up to 3 decimal places such as 3.999.
