1. The theoretical or specified length of an object, component, or material as designated by design standards or manufacturing specifications, often different from actual measured length due to tolerances
The nominal length of the pipe is 10 meters, but it may vary within acceptable tolerances.
O comprimento nominal do tubo é de 10 metros, mas pode variar dentro das tolerâncias aceitáveis.
2. In engineering and manufacturing, the ideal or standard dimension used as a basis for calculating tolerances and acceptable variations
Engineers specified a nominal length of 500mm for the steel rod.
Os engenheiros especificaram um comprimento nominal de 500mm para a barra de aço.
