izindaba

Ngokuya ngezidingo zendlela yokwenza nokunemba kwenhlangano, inani elifanele lebanga lokubekezelela lizokhethwa ukuze kunwetshwe.Ubukhulu obungenayo inkomba yokubekezelelana emdwebeni buzocaciswa ngokuvumelana nezidingo ze-GB / t1804-2000 "ukubekezelelana komugqa kanye ne-angular ngaphandle kwenkomba yokubekezelela".

Ukumelwa okujwayelekile komdwebo ngaphandle kwenkomba yokubekezelelana

Maka inombolo evamile kanye nekhodi yebanga lokubekezelela eduze kwebhlogo yesihloko somdwebo noma ezimfuneko zobuchwepheshe kanye nemibhalo yezobuchwepheshe (njengamazinga ebhizinisi).Isibonelo, lapho ukhetha ileveli emaphakathi, ilebula imi kanje:

I-GB/T 1804-m

Izakhiwo ezingaphawulwanga ngokubekezelelana kwejiyomethri emidwebeni zizomakwa ngokwezinga le-GB / t1184-1996 “ukubekezelelana kwejometri nokuma kwesikhundla ngaphandle kwamanani okubekezelela umuntu ngamunye”.[1]
