Methods of measurement of touch current and protective conductor current
IEC 60990:2016 is available as IEC 60990:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60990:2016 defines measurement methods for d.c. or a.c. current of sinusoidal or non-sinusoidal waveform, which could flow through the human body, and current flowing through a protective conductor. The measuring methods recommended for TOUCH CURRENT are based upon the possible effects of current flowing through a human body. In this standard, measurements of current through networks representing the impedance of the human body are referred to as measurements of TOUCH CURRENT. These networks are not necessarily valid for the bodies of animals. The specification or implication of specific limit values is not within the scope of this standard. IEC TS 60479 series provides information regarding the effects of current passing through the human body from which limit values may be derived. This standard is applicable to all classes of EQUIPMENT, according to IEC 61140. The methods of measurement in this standard are not intended to be used for TOUCH CURRENTS having less than 1 s duration, patient currents as defined in IEC 60601-1, a.c. at frequencies below 15 Hz, and currents above those chosen for ELECTRIC BURN limits. This third edition cancels and replaces the second edition published in 1999. It constitutes a technical revision. The principal changes in this edition as compared with the second edition are as follows: - the effects names have been updated to reflect increased understanding of the range of effects and is in concert with present usage; - the conditions of use invoking a GRIPPABLE PART have been reduced in the application of the requirements based upon the current understanding of this effect; - the references to ISO 10012-1, which has been replaced by management standard of the same number, have been replaced with explanatory text, where needed to maintain the sense of the document; - former informative Annex H (GRIPPABLE PART) has been deleted from this update as it does not properly represent the full set of conditions under which immobilization can occur. A new informative Annex H (Analysis of frequency filtered touch current circuits measurement) has been added and the Bibliography (formerly Annex M) has been updated with additional references for completeness. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies independent of product standards. Key words: Touch Current, Protective Conductor Current, Current Flow
Verfahren zur Messung von Berührungsstrom und Schutzleiterstrom
Méthodes de mesure du courant de contact et du courant dans le conducteur de protection
L'IEC 60990:2016 définit des méthodes de mesure pour les courants continus ou les courants alternatifs de forme d'onde sinusoïdale ou non sinusoïdale qui peuvent traverser le corps humain, et les courants qui peuvent circuler dans un conducteur de protection. Les méthodes de mesure recommandées pour le COURANT DE CONTACT sont basées sur les effets possibles provoqués par le passage du courant dans le corps humain. Dans la présente norme, les mesurages de courant à travers des réseaux représentant l'impédance du corps humain sont appelés mesurages du COURANT DE CONTACT. Les réseaux utilisés ne sont pas nécessairement valables pour des animaux. La spécification ou l'implication de valeurs limites spécifiques ne fait pas partie du domaine d'application de la présente norme. La série IEC TS 60479 fournit des informations concernant les effets du courant traversant le corps humain, à partir desquelles des valeurs limites peuvent être déduites. La présente norme est applicable à toutes les classes de MATERIELS, conformément à l'IEC 61140. Les méthodes de mesure indiquées dans la présente norme ne sont pas destinées à être utilisées pour les COURANTS DE CONTACT de durée inférieure à 1 s, les courants patients tels qu'ils sont définis dans l'IEC 60601-1, les courants alternatifs de fréquence inférieure à 15 Hz, et les courants supérieurs aux courants choisis pour les limites de BRULURE ELECTRIQUE. Cette troisième édition annule et remplace la deuxième édition, parue en 1999. Cette édition constitue une révision technique. Cette édition inclut les modifications majeures suivantes par rapport à la deuxième édition: - les désignations des effets ont été mises à jour pour refléter la meilleure compréhension de la plage des effets et s'accorder avec l'utilisation actuelle; - les conditions d'utilisation impliquant une PARTIE PREHENSIBLE ont été réduites pour l'application des exigences fondées sur la compréhension actuelle de cet effet; - les références à l'ISO 10012-1, qui a été remplacée par une norme de management portant le même numéro, ont été remplacées par un texte explicatif, le cas échéant, afin de conserver le sens du document; - l'ancienne Annexe H informative (PARTIE PREHENSIBLE) a été supprimée de cette mise à jour car elle ne représente pas de manière adéquate l'intégralité des conditions dans lesquelles une immobilisation est susceptible de se produire. Une nouvelle Annexe H informative (Analyse du mesurage de circuits de courant de contact avec filtre de fréquence) a été ajoutée et la Bibliographie (anciennement dénommée Annexe M) a été mise à jour avec des références supplémentaires par souci d'exhaustivité. La présente publication fondamentale de sécurité est destinée principalement à être utilisée par les comités d'études lors de la préparation de normes conformément aux principes figurant dans le Guide IEC 104 et le Guide ISO/IEC 51. Elle n'est pas destinée à être utilisée par les fabricants ou les organismes de certification indépendants de normes de produit.

Metode merjenja toka dotika in toka v zaščitnem vodniku
Ta mednarodni standard opredeljuje metode merjenja za:
– enosmerni ali izmenični tok sinusoidne ali nesinusoidne valovne oblike, ki lahko teče skozi človeško telo, in
– tok, ki teče skozi zaščitni vodnik.
Metode, priporočene za merjenje TOKA DOTIKA, temeljijo na možnih učinkih toka, ki teče skozi človeško telo. Meritve toka v omrežjih, ki predstavljajo impedanco človeškega telesa, se v tem standardu imenujejo meritve TOKA DOTIKA. Ta omrežja ne veljajo nujno za živalska telesa.
Specifikacija ali vpliv določenih mejnih vrednosti nista zajeta v tem standardu.
Skupina standardov IEC TS 60479 vsebuje informacije v zvezi z učinki toka, ki teče skozi človeško telo, na podlagi katerih je mogoče izračunati mejne vrednosti.
V skladu s standardom IEC 61140 se ta standard uporablja za vse razrede OPREME.
Metode merjenja v tem standardu niso namenjene za uporabo za:
– TOKE DOTIKA, ki trajajo manj kot 1 s,
– tokove bolnikov, kot so opredeljeni v standardu IEC 60601-1,
– izmenični tok s frekvencami, nižjimi od 15 Hz, in
– tokove z vrednostmi nad mejnimi vrednostmi za ELEKTRIČNE OPEKLINE.
Ta osnovna varnostna publikacija je namenjena predvsem tehničnim odborom za pripravo standardov v skladu z načeli vodil IEC 104 in ISO/IEC 51. Ni namenjena proizvajalcem ali certifikacijskim organom, ki so neodvisni od standardov za proizvode.
Ena od pristojnosti tehničnih odborov je, da med pripravo publikacij uporabljajo osnovne varnostne publikacije, kadar je to primerno. Zahteve, preskusne metode ali preskusni pogoji iz te osnovne varnostne publikacije se uporabljajo le, če so izrecno navedeni ali zajeti v ustreznih publikacijah.
