IEC 60870-5-101:2003/AMD1:2015

Amendment 1 - Telecontrol equipment and systems - Part 5-101: Transmission protocols - Companion standard for basic telecontrol tasks

Describes a test method which can provide preliminary differentiation between similar insulating materials, with respect to their resistance to damage when exposed to high-voltage, low-current arc discharges, occurring close to their surfaces.  Due to its convenience and the short time required for testing, the test method is applicable for preliminary screening of test materials, for detecting the effects of changes in formulation and for quality control testing.

Amendement 1 - Matériels et systèmes de téléconduite - Partie 5-101: Protocoles de transmission - Norme d'accompagnement pour les tâches élémentaires de téléconduite

Décrit une méthode d'essai permettant, dans un premier temps, une différenciation parmi des matériaux isolants similaires, selon leur résistance aux dommages quand ils sont exposés à des décharges haute tension, faible courant se produisant à proximité de la surface.  La méthode d'essai s'applique en raison de sa commodité et de la brièveté nécessaire de l'essai, pour faire un contrôle préliminaire des matériaux, afin de détecter l'effet des modifications dans la composition, et pour des essais de contrôle de qualité.

Replace the existing Note below Table 9 with the following new Note:
NOTE ASDUs marked (CON) in control direction are confirmed application services and have to be mirrored in
