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 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. It has the status of a group safety publication in accordance with IEC GUIDE 104. IEC 61010-031 is a stand-alone standard. This second edition cancels and replaces the first edition published in 2002 and Amendment 1:2008. This edition constitutes a technical revision. This edition includes the following significant changes from the first edition, as well as numerous other changes:
a) Voltages above the levels of 30 V r.m.s., 42,4 V peak, or 60 V d.c. are deemed to be HAZARDOUS LIVE instead of 33 V r.m.s., 46,7 V peak, or 70 V d.c.
b) Servicing is now included within the scope.
c) Extended environmental conditions are included within the scope.
d) New terms have been defined.
e) Tests for REASONABLY FORESEEABLE MISUSE have been added, in particular for fuses.
f) Additional instruction requirements for probe assembly operation have been specified.
g) Limit values for ACCESSIBLE parts and for measurement of voltage and touch current have been modified.
h) SPACINGS requirements for mating of CONNECTORS have been modified.
i) PROBE TIPS and SPRING-LOADED CLIPS requirements have been modified. The PROTECTIVE FINGERGUARD replace the BARRIER with new requirements.
j) Insulation requirements (6.5) and test procedures (6.6.5) have been rewritten and aligned when relevant with Part 1. Specific requirements have been added for solid insulation and thin-film insulation.
k) The terminology for MEASUREMENT CATEGORY I has been replaced with the designation "not RATED for measurements within MEASUREMENT CATEGORIES II, III, or IV".
l) The flexing/pull test (6.7.4.3) has been partially rewritten.
m) Surface temperature limits (Clause 10) have been modified to conform to the limits of IEC Guide 117.
n) Requirements for resistance of PROBE WIRES to mechanical stresses have been added in Clause 12 and a new Annex D.
o) Requirements have been added regarding the prevention of HAZARD from arc flash and short-circuits for SPRING-LOADED CLIPS.
p) A new informative Annex E defines the dimension of the 4 mm banana CONNECTORS.
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
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.
