Olu luhlu lweswitshi yokuzihlukanisa lulandelwa "utshintshiselwano lwe-GB 1985-89 oluphezulu lukhusela iswitshi".
IEC129(1984> (itshintshiselana ngokuvala iswitshi ngokudibanisa iswitshi esijikelezayo) kunye nezixhobo zeswitshi zoxinzelelo oluphezulu ze-IEC694 (1980) ezinolawulo lwezixhobo ukuze zilawule into "ngezicelo ezahlukeneyo ngokupheleleyo."
