Safety of machinery - Electrical equipment of machines - Part 33: Requirements for semiconductor fabrication equipment (IEC 60204-33:2009, modified)
This part of IEC 60204 applies to electrical and electronic equipment associated with semiconductor fabrication equipment for the manufacture, measurement, assembly, and test of
semiconductors.
NOTE 1 In this standard, the term electrical includes electrical, electronic, and programmable electronic matters (i.e. electrical equipment means electrical, electronic, and programmable electronic equipment).
NOTE 2 In the context of this standard, the term person refers to any individual and includes those persons who are assigned and instructed by the user or his agent(s) in the installation, use, and care of the fabrication equipment in question.
The electrical equipment covered by this standard commences at the point of connection of the
supply to the electrical equipment (see 5.1), and includes proper instruction for its safe installation.
NOTE 3 For the requirements for the electrical supply installation in buildings, see IEC 60364 series.
This part is applicable to the electrical equipment or parts of the electrical equipment that operate with nominal supply voltages not exceeding 1 000 V for alternating current (a.c.) and not exceeding 1 500 V for direct current (d.c.), and with nominal supply frequencies not exceeding 200 Hz. For higher voltages or frequencies, special requirements may be needed.
NOTE 4 Electrical equipment within which derived voltages exceed these supply voltage limits is within the scope of this standard.
Included are requirements for protective measures against electrical safety hazards as well as electrical interlock circuits that protect against non-electrical hazards. However, it does not cover all the requirements that are needed or required by other standards or regulations in order to safeguard persons from hazards other than electrical hazards (e.g. chemical hazards, mechanical hazards, radiation hazards). Each type of machine has unique requirements to be accommodated to provide adequate safety.
Additional and special requirements can apply to the electrical equipment of fabrication equipment that:
use, process, or produce potentially explosive material;
are used in potentially explosive and/or flammable atmospheres;
have special risks when producing or using certain materials;
are hoisting machines (which are covered by IEC 60204-32).
This standard does not include specifications for performance or functional characteristics of the fabrication equipment.
This standard does not deal with the possible effects on human health that can result from emissions (for example EMFs, noise) from the fabrication equipment.
This standard does not specify requirements for electromagnetic compatibility (EMC).

Sécurité des machines - Equipement électrique des machines - Partie 33: Exigences pour les equipments de fabrication des semi-conducteurs (CEI 60204-33:2009, modifiée)
La CEI 60204-33:2009 s'applique aux équipements électriques et électroniques associés aux équipements de fabrication des semi-conducteurs pour la fabrication, les mesures, l'assemblage et les essais des semi-conducteurs. Elle s'applique aux équipements ou parties d'équipement électrique qui sont alimentés sous une tension d'alimentation nominale n'excédant pas 1 000 V en courant alternatif (c.a.) ou 1 500 V en courant continu (c.c.) et pour des fréquences nominales d'alimentation n'excédant pas 200 Hz. Pour des tensions ou des fréquences supérieures, des exigences particulières peuvent être nécessaires.
Varnost strojev - Električna oprema strojev - 33. del: Zahteve za opremo za izdelovanje polprevodnikov (IEC 60204-33:2009, spremenjen)
Ta del IEC 60204 velja za električno in elektronsko opremo, povezano z opremo za izdelovanje polprevodnikov, ki se uporablja za proizvodnjo, merjenje, sestavljanje in preskušanje polprevodnikov.
OPOMBA 1: V tem standardu izraz električni vključuje električne, elektronske in programirljive elektronske predmete (tj. električna oprema pomeni električno, elektronsko in programirljivo elektronsko opremo).
OPOMBA 2: V okviru tega standarda se izraz oseba nanaša na vse posameznike in vključuje tiste osebe, ki jih uporabnik ali njegov(-i) zastopnik(-i) določijo in usposobijo za namestitev in uporabo zadevne opreme za izdelavo ter za skrb zanjo.
Električna oprema, ki jo zajema ta standard, se začne na točki povezave napajanja z električno opremo (glej točko 5.1) in vključuje ustrezna navodila za varno namestitev.
OPOMBA 3: Za zahteve za električne inštalacije za napajanje v stavbah glej serijo IEC 60364.
Ta del velja za električno opremo ali dele električne opreme, ki obratujejo z nazivno napajalno napetostjo, ki ne presega 1000 V za izmenični tok (a.c.) in 1500 V za enosmerni tok (d.c.), in z nazivnimi frekvencami napajanja, ki ne presegajo 200 Hz. Za višje napetosti ali frekvence so morda potrebne posebne zahteve.
OPOMBA 4: Ta standard zajema tudi električno opremo, v kateri izpeljane napetosti presegajo navedene meje napajalne napetosti.
Vključene so zahteve za zaščitne ukrepe proti električnim nevarnostim in za električna zaporna vezja, ki ščitijo pred neelektričnimi nevarnostmi. Ne zajema pa vseh zahtev, ki so potrebne ali jih zahtevajo drugi standardi ali predpisi za zaščito oseb pred drugimi nevarnostmi, razen električnih (npr. kemičnimi nevarnostmi, mehanskimi nevarnostmi, nevarnostmi sevanja). Pri vsaki vrsti stroja je za zagotavljanje ustrezne varnosti treba upoštevati edinstvene zahteve.
Dodatne in posebne zahteve lahko veljajo za električno opremo za izdelovanje, ki:
uporablja, obdeluje ali proizvaja potencialno eksploziven material;
se uporablja v potencialno eksplozivni in/ali vnetljivi atmosferi;
je posebej tvegana pri proizvodnji ali uporabi nekaterih materialov;
so dvižni stroji (ki jih zajema IEC 60204-32).
Ta standard ne vključuje specifikacij za delovanje ali funkcijske značilnosti opreme za izdelovanje.
Ta standard ne obravnava morebitnih učinkov na človeško zdravje, do katerih lahko pride zaradi emisij (na primer elektromagnetnih polj, hrupa) iz opreme za izdelovanje.
Ta standard ne določa zahtev za elektromagnetno skladnost (EMC).
