AS/NZS IEC 62716:2023 identically adopts IEC 62716:2013 and its Corrigendum No. 1 (2014) which describes test sequences useful to determine the resistance of PV modules to ammonia (NH3). Photovoltaic (PV) modules are electrical devices intended for continuous outdoor exposure during their lifetime. Highly corrosive wet atmospheres could eventually degrade some of the PV module components causing permanent damages that could impair their functioning and safe operation
