Chapter 5: Reference
Specifications and Characteristics
referred to as an "operational accuracy calibration".
What is a Characteristic?
Characteristics describe product performance that is useful in the
application of the product, but that is not covered by the product
warranty. Characteristics describe performance that is typical of the
majority of a given product, but not subject to the same rigor
associated with specifications.
Characteristics are verified by Function Tests.
What is a Function
Test?
Function tests are quick tests designed to verify basic operation of a
product. Function tests include operator's checks and operation
verification procedures. An operator's check is normally a fast test
used to verify basic operation of a product. An operation verification
procedure verifies some, but not all, specifications, and often at a lower
confidence level than a calibration procedure.
