معاني الرموز الموجودة على القطع والاجهزة

[أحمد الجزائري]

كلنا عندما نشتري اجهزة او قطع جديدة نلاحط وجود عليها بعض الكتابات والرموز لا نعرف سبب وجودها
وفي هذا الموضوع سوف اوضح سبب وجودها

http://www.qariya.com/pc/images/ul_mark_qariya.jpg ستجد هذا الرمز بكثره على الاجهزة والمعدات الكهربائية .. وهو سيعطيك أطمئنان بأن هذا المنتج آمن جدا من ناحية السلامة والأمان في الاستخدام .. لانه يدل ببساطة على ان الجهاز الموجود بين يديك تم ترخيصة من اعلى هيئة عالمية تهتم بالسلامة وهي Underwriters Laboratories والمعروفة بالرمز UL
هذا الرمز مهم جدا خاصة للفنين والخبراء وتسعى كل المؤسسات والمصانع لأشراكه على منتجاتها لأنه يعني لها الكثير
