Specification

Seen on pass or fail statements.

Definition

An agreed acceptance limit against which a measured value is judged. Without one, the laboratory reports the measured value and does not imply a universal acceptance threshold.

"Pass" is only meaningful when a specification and its source are stated. A pass with no named specification is a claim about nothing.
