Defining Specifications
When a set of tests apply to more than one item, set up the specification in
Master Specification Maintenance (19.1.1). A master specification is a
list of index numbers, characteristics, specifications, and units of
measure, and additional information entered as transaction comments.
You can include tolerances, or acceptable deviations from standard value.
These specifications are used by quality orders and in-process inspection
operations.
The index numbers associated with characteristics and specifications
must be unique but need not correspond to an actual test or inspection
sequence.
Specification Values
A specification can take any of the following forms.
A character string. This is a list of elements separated by commas. For
example, if acceptable colors for an item are gray and black, the
specification is gray, black.
A numeric value with a tolerance. This is stated as a range, with minimum
and maximum values separated by the pipe (|) character. For example, if
the idle speed of an engine is 1000 +/– 150 rpm, the specification is 850 |
1150. To generate the pipe character, press Shift-\.
You can also designate a range within a range. In the previous example, a
range of +/– 50 rpm, together with a tolerance of +/– 150, is designated by
the string 850 | 950 | 1050 | 1150. The system looks only at minimum and
maximum values, but this format allows you to see the optimal range
within a tolerance.
