EN IEC 61326-3-2:2018

Electrical equipment for measurement, control and laboratory use - EMC requirements - Part 3-2: Immunity requirements for safety-related systems and for equipment intended to perform safety-related functions (functional safety) - Industrial applications with specified electromagnetic environment

This part of IEC 61326 covers all equipment within the scope of IEC 61326-1, but is limited to systems and equipment for industrial applications within a specified electromagnetic environment and intended to perform safety functions as defined in IEC 61508 with SIL 1-3. The electromagnetic environments encompassed by this product family standard are industrial, both indoor and outdoor, and based on the requirements of the process industry, specifically chemical/petrochemical/pharmaceutical manufacturing plants using the mitigation measures given in Annex C. The difference between the electromagnetic environment covered by this document compared to the general industrial environment (see IEC 61326-3- 1) is due to the mitigation measures employed against electromagnetic phenomena leading to a specified electromagnetic environment with test values that have been proven in practice. The environment of industrial application with a specified electromagnetic environment typically includes the following characteristics: – industrial area with limited access; – limited use of mobile transmitters; – dedicated cables for power supply and control, signal or communication lines; – separation between power supply and control, signal or communication cables; – factory building mostly consisting of metal construction; – overvoltage/lightning protection by appropriate measures (for example, metal construction of the building or use of protection devices); - pipe heating systems driven by AC main power; - no high-voltage substation close to sensitive areas; - presence of CISPR 11 Group 2 ISM equipment using ISM frequencies only with low power; - competent staff; - periodical maintenance of equipment and systems; - mounting and installation guidelines for equipment and systems. Equipment and systems considered as "proven-in-use" according to IEC 61508 or "prior use" according to IEC 61511 are excluded from the scope of this document. Fire alarm systems and security alarm systems intended for protection of buildings are excluded from the scope of this document.

NEW!IEC 61326-3-2:2017 est disponible sous forme de IEC 61326-3-2:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 61326-3-2:2017 couvre tous les matériels qui relèvent du domaine d’application de l’IEC 61326-1, mais est limitée aux systèmes et matériels pour applications industrielles dans un environnement électromagnétique spécifié et destinés à réaliser des fonctions de sécurité telles que définies dans l’IEC 61508, avec un niveau d’intégrité de sécurité (SIL) 1-3. Cette deuxième édition annule et remplace la première édition parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - extension de la plage de fréquences jusqu’à 6 GHz pour l’essai de champ électromagnétique à fréquence radioélectrique, conformément à l’IEC 61000-4-3, - remplacement du critère de performance FS par DS, conformément à la norme générique IEC 61000-6-7, - ajout du Tableau 1 – aspects à prendre en considération lors de l'application du critère de performance DS, - intégration d’essais d’immunité pour les dispositifs ayant une consommation de courant > 16 A, conformément à l’IEC 61000-4-34, - mise à jour de la Figure A.1 et de la Figure 1 pour une meilleure lisibilité, - ajouts d’essais conformes à l’IEC 61000-4-16 afin de remplacer les essais conformes à l’IEC 61000-4-6 dans la plage de fréquences comprises entre 10 kHz et 150 kHz.

Električna oprema za merjenje, nadzor in laboratorijsko uporabo - Zahteve za elektromagnetno združljivost (EMC) - 3-2. del: Zahteve za odpornost varnostnih sistemov in za opremo, namenjeno za izvajanje z varnostjo povezanih funkcij (funkcijska varnost) - Industrijska uporaba v določenih elektromagnetnih okoljih (IEC 61326-3-2:2017)

Ta del standarda IEC 61326 zajema vso opremo, ki sodi v področje uporabe standarda IEC 61326-1, vendar se omejuje na sisteme in opremo za industrijsko uporabo znotraj določenega elektromagnetnega okolja, ki so namenjeni izvajanju varnostnih funkcij, kot je opredeljeno v standardu IEC 61508 pri ravni celovite varnosti 1–3.
Elektromagnetna okolja, ki jih zajema ta standard družine izdelkov, so industrijska, tako v zaprtih prostorih kot na prostem, in temeljijo na zahtevah procesne industrije, zlasti proizvodnih obratov za kemikalije/petrokemijo/farmacijo, ki uporabljajo ukrepe za ublažitev, podane v dodatku C. Razlika med elektromagnetnim okoljem, ki ga zajema ta dokument, in splošnim industrijskim okoljem (glej IEC 61326-3-1) nastane zaradi ukrepov za ublažitev, ki se uporabljajo za elektromagnetne pojave, ki povzročajo določeno elektromagnetno okolje s preskusnimi vrednostmi, ki so bile dokazane v praksi.
Okolje industrijske uporabe z določenim elektromagnetnim okoljem običajno vključuje naslednje značilnosti:
– industrijsko območje z omejenim dostopom;
– omejena uporaba mobilnih oddajnikov;
– namenski kabli za napajanje in nadzor, signalne ali komunikacijske linije;
– ločevanje med napajanjem in nadzorom, signalni ali komunikacijski kabli;
– zgradba tovarne, ki je večinoma sestavljena iz kovinske konstrukcije;
– zaščita pred prenapetostjo/udari strel z ustreznimi ukrepi (na primer kovinska konstrukcija zgradbe ali uporaba zaščitnih naprav);
– cevni sistemi za ogrevanje, ki se napajajo iz električnega omrežja z izmeničnim tokom;
– brez visokonapetostnih podpostaj v bližini občutljivih območij;
– prisotnost opreme CISPR 11 Group 2 ISM, ki uporablja frekvence ISM izključno z nizko stopnjo moči;
– usposobljeno osebje;
– redno vzdrževanje opreme in sistemov;
– smernice za montažo ter namestitev opreme in sistemov.
Oprema in sistemi, ki so obravnavani kot »dokazani z uporabo« v skladu s standardom IEC 61508 ali kot »pred uporabo« v skladu s standardom IEC 61511, ne spadajo na področje uporabe tega dokumenta.
Sistemi za javljanje požara in varnostni alarmni sistemi, namenjeni za zaščito stavb, ne spadajo na področje uporabe tega dokumenta.
