| Requirement for the Diameter: 1000mm |  |
According to ISO 9000:2000 a Specification
is defined as "a Document stating requirements".
Another definition of Specification is "The
engineering requirement for judging acceptability of a particular
characteristic. Chosen with respect to functional or customer
requirements for the product, a specification may or may not be
consistent with the demonstrated capability of the process (if it
is not, out-of-specification parts are certain to be made). A
specification should never be confused with a control limit"
A specification might contain the ideal
measurement, tolerances for these measurements, material type and
the processes to be used for manufacturing the product.
Here an example for a Specification of
zylindrically shaped shaft:
Material to be used: Steel
Machinery to be used: Lath
| Requirement for the Diameter: 1000mm | |
 |
The minimum Diameter for the shaft is: 995mm |
| The maximum Diameter for the shaft is: 1005mm |  |
 |
The range were the diameter is allowed to fall in is 10mm. The tolerance therefore is 0.5% . |
Specifications might also be given
for Service Processes
