Method for the determination of the proof and the comparative tracking indices of solid insulating materials

IEC 60112:2020 specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltage. This document provides a procedure for the determination of erosion when required. This test method evaluates the composition of the material as well as the surface of the material being evaluated. Both the composition and surface condition directly influence the results of the evaluation and are considered when using the results in material selection process. Test results are not directly suitable for the evaluation of safe creepage distances when designing electrical apparatus. This basic safety publication focusing on a safety test method is primarily intended for use by technical committees in the preparation of safety publications in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. This edition includes the following significant technical changes with respect to the previous edition:  
Introduction of a new contaminant, solution C with a surfactant aligned with the test method of IEC 60587. The definition of the solution B was transferred to Annex B for backward reference.
Introduction of a screening test, considering the fact that some materials can withstand high test voltages, but fail at lower test voltages.  It has the status of a basic safety publication in accordance with IEC Guide 104.

Méthode de détermination des indices de résistance et de tenue au cheminement des matériaux isolants solides

L'IEC 60112:2020 spécifie la méthode d’essai pour la détermination des indices de résistance et de tenue au cheminement des matériaux isolants solides sur des échantillons prélevés sur des parties d'équipement et des plaques de matériau en utilisant une tension alternative. Le présent document fournit une procédure pour la détermination de la valeur de l’érosion quand cela est exigé. Cette méthode d’essai évalue la composition et la surface du matériau soumis à l’essai. La composition et les conditions de surface influencent directement les résultats de l’évaluation et sont prises en considération lors de l’utilisation des résultats au moment de la sélection des matériaux. Les résultats d’essais tels quels ne sont pas adaptés à l’évaluation des lignes de fuite de sécurité lors de la conception des appareils électriques. La présente publication fondamentale de sécurité portant sur une méthode d’essai de sécurité est avant tout destinée à être utilisée par les comités d’études dans le cadre de l’élaboration de publications de sécurité, conformément aux principes établis dans le Guide IEC 104 et le Guide lSO/lEC 51. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:  
Introduction d’un nouveau contaminant, la solution C, avec un tensioactif aligné sur la méthode d’essai de l’IEC 60587. Transfert à l’Annexe B de la définition de la solution B pour référence arrière.
Introduction d’un essai de déverminage, en tenant compte du fait que certains matériaux peuvent supporter des tensions d’essai élevées, mais pas des tensions d’essai plus basses.  Elle a le statut de publication fondamentale de sécurité, conformément au Guide IEC 104.
