Nuclear instrumentation - Constructional requirements and classification of radiometric gauges
IEC 62598:2011 applies to the manufacture and installation of electrical measuring systems and instruments utilizing radioactive sources (radiometric gauges, hereinafter called gauges). It also applies to source housings intended for use in the aforementioned measuring systems. This standard applies to equipment, which is not related to power production or to the fuel cycle. It specifies constructional requirements for the design of instruments utilizing radioactive sources in regard of radiation protection. This standards cancels and replaces IEC 60405.

Instrumentation nucléaire - Exigences de construction et classification pour les jauges radiométriques
La CEI 62598:2011 s'applique à la fabrication et à l'installation des systèmes et appareils de mesure électriques utilisant des sources radioactives (jauges radiométriques, ci-après désignées par jauges, en abrégé). Elle s'applique également aux boîtiers des sources destinées à être utilisées dans les systèmes de mesure mentionnés ci-dessus. Cette Norme s'applique à un équipement, qui n'est pas relié à la production d'électricité nucléaire ou au cycle du combustible nucléaire. Cette Norme spécifie les exigences de construction concernant la conception des instruments utilisant des sources radioactives, eu égard à la protection contre le rayonnement. Cette norme annule et remplace la CEI 60405.
Jedrska merilna oprema - Konstrukcijske zahteve in razvrstitev radiometričnih merilnikov
Ta mednarodni standard se uporablja za izdelavo ter namestitev električnih merilnih sistemov in instrumentov, ki uporabljajo radioaktivne vire (radiometrični merilniki, v nadaljevanju »merilniki«). Uporablja se tudi za ohišja virov, ki so namenjeni za uporabo v omenjenih merilnih sistemih. Ta standard se uporablja za opremo, ki ni povezana s proizvodnjo energije ali ciklom goriva. Ne uporablja se za prenosljive merilnike, ki so poleg svoje zasnove in namenske uporabe zasnovani tako, da se upravljajo kot mobilna oprema, ter za merilnike, ki se upravljajo z rentgenskimi cevmi, vendar se lahko analogno uporablja za te merilnike. Namen tega standarda je določitev konstrukcijskih zahtev za oblikovanje instrumentov, ki uporabljajo radioaktivne vire, v povezavi z zaščito pred sevanjem. Ta standard ne obravnava mehanskih tveganj ali nevarnosti zaradi elektrike.
