SIST EN ISO 80000-2 : 2019
NACIONALNI UVOD

Standard SIST EN ISO 80000-2:2019 (sl), Veličine in enote – 2. del: Matematika (ISO 80000-2:2019,
popravljena verzija 2021-11), ima status slovenskega standarda in je istoveten evropskemu standardu
EN ISO 80000-2:2019 (en), Quantities and units – Part 2: Mathematics (ISO 80000-2:2019, popravljena
verzija 2021-11).

Ta standard nadomešča SIST EN ISO 80000-2:2013 in SIST ISO 80000-2:2013.

NACIONALNI PREDGOVOR

Evropski standard EN ISO 80000-2:2019 je pripravil tehnični odbor ISO/TC 12 "Veličine in enote" v
sodelovanju s tehničnim odborom CEN/SS F02 "Enote in simboli", katerega sekretariat vodi CCMC.

Slovenski standard SIST EN ISO 80000-2:2019 je prevod evropskega standarda EN ISO 80000-2:2019.
V primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni evropski
standard v angleškem jeziku. Slovensko izdajo standarda je pripravil tehnični odbor SIST/TC TRS
Tehnično risanje, veličine, enote, simboli in grafični simboli.

Odočitev za izdajo tega standarda je 16. 10. 2019 sprejel SIST/TC TRS Tehnično risanje, veličine,
enote, simboli in grafični simboli.

ZVEZA Z NACIONALNIMI STANDARDI

S privzemom tega evropskega standarda, ki je istoveten mednarodnemu standardu, veljajo za omejeni
namen referenčnih standardov vsi standardi, navedeni v izvirniku, razen standardov, ki so že sprejeti v
nacionalno standardizacijo:

SIST EN ISO 80000-1:2023 (en) Veličine in enote – 1. del: Splošno (ISO 80000-1:2022)

PREDHODNA IZDAJA

– SIST ISO 80000-2:2013 (sl), Veličine in enote – 2. del: Matematični znaki in simboli za uporabo v
naravoslovnih vedah in tehniki

OPOMBE

– Povsod, kjer se v besedilu standarda uporablja izraz "evropski standard" ali "mednarodni standard",
v SIST EN ISO 80000-2:2019 to pomeni "slovenski standard".

– Nacionalni uvod in nacionalni predgovor nista sestavni del evropskega standarda.
