貪吃的狐狸
UL Listed vs Recognized. | Brooks Instrument Blog有一隻狐狸牠看到有一座葡萄園,牠很想進去吃葡萄,不過唯一能進去的路只有一點縫隙而已,牠想:「我這麼胖,要怎麼進去。」於是牠餓了三天三夜終於進去了,牠大吃大喝好快樂,牠要出去時發現牠躦不出去,牠又餓了三天三夜才出來,牠想:「我進去之前餓了三天三夜,出來又餓三天三夜,到底進去幹麻。」The topic was very much helpful to clear the doubt on UL listed & UL recognized instruments. Very much interested in the next topics ATEX approvals, International IEC standards, Canadian CRN registrations and NEMA/IP water tight ratings etc. Thanks...
