P460N Cadaadiska Weelka Birta ee Saxanka

Heerka birta ee P460N waa mid ka mid ah fasalka En10028-3, kaas oo aan ahayn birta daawaha ah iyo kuwa daawaha ah oo leh astaamo heerkul sare oo cayiman. Darajooyinka P460N waxaa loo isticmaalaa wax ka sarreeya dhammaan wax soo saarka kuleyliyeyaasha, weelasha cadaadiska iyo tuubooyinka qaada dareeraha kulul.

EN10028 darajada birta ayaa ka sarraysa heerarkii BS iyo DIN ee hore.


Codsiga ugu muhiimsan:
EN10028-3 P460N Weelka Cadaadiska iyo birta kululeeyaha waxaa loo isticmaalaa Weelka Cadaadiska, Kuleyliyaha, Haamaha Kaydka iyo Kuleyliyaha Saliida, Mashruuca Gaaska.
