This part includes two types of vibration tests: the vibration response test and the vibration endurance test, and is generally based upon IEC 68-2-6. The requirements are applicable only to measuring relays and protection equipment in a new condition. The tests specified are type tests. Cette partie comprend deux types dessais de vibrations: lessai de comportement aux vibrations et lessai dendurance aux vibrations et est basee de maniere generale sur la CEI 68-2-6. Les specifications ne sont applicables quaux relais de mesure et aux dispositifs de protection a letat neuf. Les essais specifies sont des essais de type.
