Photovoltaic (PV) modules - Test methods for the detection of potential-induced degradation - Part 1...
IEC TS 62804-1:2025 defines procedures to evaluate the durability of crystalline silicon photovoltaic (PV) modules to the effects of short-term high-voltage stress, primarily potential-induced degradation (PID). Three test methods are given. The first type, which has two variations, is conducted in the dark and is primarily designed for assessing PID-shunting. The second type, which also has two…
Le présent document spécifie les caractéristiques des écrous hauts hexagonaux autofreinés (tout métal), en acier et en acier inoxydable, à filetage métrique à pas gros M5 à M39, et de grades A et B.
NOTE Ces écrous sont conçus avec une hauteur totale hmin = mmin (tel que spécifié dans l'ISO 898-2 et l'ISO 4033 pour le style 2) plus le dispositif d’autofreinage. Les valeurs de…
