Safety requirements for electrical equipment for measurement, control and laboratory use -- Part 031: Safety requirements for hand-held probe assemblies for electrical measurement and test (IEC 61010-031:2015)

This part of IEC 61010 specifies safety requirements for hand-held and hand-manipulated probe assemblies of the types described below, and their related accessories. These probe assemblies are for direct electrical connection between a part and electrical test and measurement equipment. They may be fixed to the equipment or be detachable accessories for the equipment.
a) Type A: low-voltage and high-voltage, non-attenuating probe assemblies. Non-attenuating probe assemblies that are RATED for direct connection to voltages exceeding 30 V r.m.s., 42,4 V peak, or 60 V d.c., but not exceeding 63 kV. They do not incorporate components which are intended to provide a voltage divider function or a signal conditioning function, but they may contain non-attenuating components such as fuses (see Figure 1.)
b) Type B: high-voltage attenuating or divider probe assemblies. Attenuating or divider probe assemblies that are RATED for direct connection to secondary voltages exceeding 1 kV r.m.s. or 1,5 kV d.c. but not exceeding 63 kV r.m.s. or d.c. The divider function may be carried out wholly within the probe assembly, or partly within the test or measurement equipment to be used with the probe assembly (see Figure 2).
c) Type C: low-voltage attenuating or divider probe assemblies. Attenuating or divider probe assemblies for direct connection to voltages not exceeding 1 kV r.m.s. or 1,5 kV d.c. The signal conditioning function may be carried out wholly within the probe assembly, or partly within the test or measurement equipment intended to be used with the probe assembly (see Figure 3).
d) Type D: low-voltage attenuating, non-attenuating or other signal conditioning probe assemblies, that are RATED for direct connection only to voltages not exceeding 30 V r.m.s., or 42,4 V peak, or 60 V d.c., and are suitable for currents exceeding 8 A (see Figure 4).This standard does not apply to current sensors within the scope of IEC 61010-2-032 (Handheld and hand-manipulated current sensors), but may apply to their input measuring circuit leads and accessories.

Règles de sécurité pour appareils électriques de mesurage, de régulation et de laboratoire - Partie 031: Exigences de sécurité pour sondes équipées tenues à la main pour mesurage et essais électriques (IEC 61010-031:2015)

L'IEC 61010-031:2015 est disponible sous forme de IEC 61010-031:2015 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 61010-031:2015 spécifie les exigences de sécurité relatives aux sondes portatives et manipulées à la main correspondant aux types décrits ci-dessous, ainsi que leurs accessoires connexes. Ces sondes équipées sont prévues pour la connexion électrique directe entre une partie et un appareil de mesure et d'essai électrique. Elles peuvent être solidaires de l'appareil ou en être des accessoires détachables. Elle a le statut d'une publication groupée de sécurité conformément au Guide 104 de l'IEC. L'IEC 61010-031 est une norme autonome. Cette deuxième édition annule et remplace la première édition parue en 2002 et l'Amendement 1:2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à la première édition, ainsi que de nombreuses autres modifications:
a) Les tensions au-dessus des niveaux de 30 V efficaces (eff), 42,4 V crête ou 60 V continu (c.c.) sont réputées être des tensions ACTIVES DANGEREUSES au lieu des tensions 33 V eff, 46,7 V crête, ou 70 V c.c. b) L'entretien est désormais inclus dans le domaine d'application. c) Des conditions d'environnement étendues sont incluses dans le domaine d'application. d) De nouveaux termes ont été définis. e) Des essais relatifs à un MAUVAIS USAGE RAISONNABLEMENT PREVISIBLE ont été ajoutés, en particulier pour les fusibles. f) Des exigences complémentaires relatives aux instructions concernant l'exploitation des sondes équipées ont été spécifiées. g) Des valeurs limites pour les parties ACCESSIBLES et pour la mesure de la tension et du courant de contact ont été modifiées. h) Les exigences relatives aux ESPACEMENTS pour l'emboîtement des CONNECTEURS ont été modifiées. i) Les exigences relatives aux POINTES DE TOUCHE et aux PINCES A RESSORT ont été modifiées. Le PROTEGE-DOIGTS remplace la BARRIERE avec de nouvelles exigences. j) Les exigences relatives à l'isolation (6.5) et les procédures d'essai (6.6.5) ont été réécrites et alignées avec la Partie 1 lorsque c'est pertinent. Des exigences spécifiques ont été ajoutées pour l'isolation solide et l'isolation en couches minces. k) La terminologie pour la CATEGORIE DE MESURE I a été remplacée par la dénomination "non ASSIGNEE pour les mesures en CATEGORIES DE MESURE II, III, ou IV". l) L'essai de traction/flexion (6.7.4.3) a été partiellement réécrit. m) Les limites de température de surface (Article 10) ont été modifiées pour se conformer aux limites du Guide 117 de l'IEC. n) Des exigences relatives à la résistance des FILS DE SONDE aux contraintes mécaniques ont été ajoutées à l'Article 12 et à une nouvelle Annexe D. o) Des exigences ajoutées se rapportent à la prévention du DANGER d'explosion due à un flash d'arc électrique et de courts-circuits pour les PINCES A RESSORT. p) Une nouvelle Annexe E informative définit les dimensions des CONNECTEURS banane de 4 mm.

Varnostne zahteve za električno opremo za meritve, nadzorovanje in laboratorijsko uporabo - 031. del: Varnostne zahteve za ročne sonde za električne meritve in preskušanja (IEC 61010-031:2015)

Ta del standarda IEC 61010 določa varnostne zahteve za spodaj navedene tipe ročnih in ročno vodenih sond ter pripadajočo dodatno opremo. Te sonde so namenjene neposredni električni povezavi med delom in električnimi preskušanji ter merilno opremo. Pritrdijo se lahko na opremo ali so odstranljivi dodatki za opremo.
a) Tip A: nizkonapetostne in visokonapetostne neslabilne sonde. Neslabilne sonde, ki so NAZNAČENE za neposredno povezavo na napetosti nad 30 V efektivne izmenične napetosti, 42,4 V vršne vrednosti ali 60 V enosmerne napetosti, vendar ne presegajo 63 kV. Ne zajemajo komponent, ki so namenjene zagotavljanju funkcije razdelitve napetosti ali kondicioniranja signala, vendar lahko zajemajo neslabilne komponente, kot so varovalke (glej sliko 1).
b) Tip B: visokonapetostne slabilne ali razdelitvene sonde. Slabilne ali razdelitvene sonde, ki so NAZNAČENE za neposredno povezavo na drugotne napetosti nad 1 kV efektivne izmenične napetosti ali 1,5 kV enosmerne napetosti, vendar ne presegajo 63 kV efektivne izmenične napetosti ali enosmerne napetosti. Funkcija razdelitve se lahko v celoti izvede v sondi ali delno v preskusni ali merilni opremi, ki se uporablja s sondo (glej sliko 2).
c) Tip C: nizkonapetostne slabilne ali razdelitvene sonde. Slabilne ali razdelitvene sonde za neposredno povezano na napetosti, ki ne presegajo 1 kV efektivne izmenične napetosti ali 1,5 kV enosmerne napetosti. Funkcija kondicioniranja signala se lahko v celoti izvede v sondi ali delno v preskusni ali merilni opremi, ki je namenjena uporabi s sondo (glej sliko 3).
d) Tip D: nizkonapetostne slabilne, neslabilne ali druge sonde za kondicioniranje signala, ki so NAZNAČENE za neposredno povezavo le na napetosti pod 30 V efektivne izmenične napetosti ali 42,4 V vršne vrednosti ali 60 V enosmerne napetosti in so primerne za tok nad 8 A (glej sliko 4). Ta standard se ne uporablja za tokovne senzorje znotraj področja uporabe standarda IEC 61010-2-032 (Ročni in ročni vodeni tokovni senzorji), vendar se lahko uporabljajo za njihove vhodne merilne tokovne vode in dodatno opremo.
