Igiciro cyuruganda 304 cyangwa 316 Ibisanzwe Byuma Bitagira Umuyoboro / Urunigi rwo Kuzamura
Icyiciro
Kuzamura no gukubita, urunigi, urunigi rugufi, kuzamura uruziga ruzengurutse, Urwego rwa 80, urunigi rwa G80, urunigi rw'umunyururu, urunigi rw'iminyururu, DIN 818-2 urunani rwo kwihanganira urunigi rwo mu cyiciro cya 8, urunigi rw'icyuma
Gusaba
Kuzamura no gukubita, imitwaro yo guterura, imizigo ihuza
Nkuruganda rukora ibyuma bizenguruka imyaka 30, uruganda rwacu rwabanye kandi rukora mugihe cyingenzi cyane cyurwego rwubushinwa rukora ubwihindurize mu nganda zita ku bucukuzi bw'amabuye y'agaciro (cyane cyane ikirombe cy'amakara), guterura ibiremereye, hamwe no gutanga inganda zisabwa imbaraga nyinshi Urunigi rw'icyuma. Ntabwo duhwema kuba abambere bayobora uruziga ruhuza ibicuruzwa mu Bushinwa (hamwe nibitangwa buri mwaka hejuru ya 10,000T), ariko dukomezanya no guhanga udushya no guhanga udushya.
Igishushanyo 1: Icyiciro cya 80 Urunigi ruhuza ibipimo
