Specification Definitions
Nominal value (nom.) – ensured by design, not tested. Measured value (min, max) – expected and warranted product performance obtained
from the actual measurements of product sample. Non-traceable measured value (n. trc. meas.) – expected product performance obtained
from the actual measurements of a product sample by means of using Farran’s own equipment and methods. Traceable only to Farranlaboratory equipment. Typical data (typ.) – value that represents the product specification met over 90% of bandwidth or a mean value.
Specifications without limits – represent the warranted product performance; with values of no or a negligible deviation from the given value
and as such have a secondary impact on the product performance.
