Mhando dzemirwi yesimbi
Maererano ne "Murwi wesimbi inopisa yakamonerwa” (GB∕T 20933-2014), murwi wesimbi wakaputirwa unopisa une mhando nhatu, mhando dzacho uye mazita adzo emakodhi ndeaya anotevera:Murwi wesimbi werudzi rweU, zita rekodhi: Murwi wesimbi werudzi rwePUZ, zita rekodhi: Murwi wesimbi wePZ wakatwasuka, zita rekodhi: PI Cherechedza: apo P iri bhii rekutanga remurwi wesimbi muChirungu (Pile), uye U, Z, uye I zvinomirira chimiro chemurwi wesimbi wesimbi.
Semuenzaniso, murwi wesimbi wemhando yeU unonyanya kushandiswa, PU-400X170X15.5, unogona kunzwisiswa sewakafara 400mm, kukwirira 170mm, ukobvu 15.5mm.
murwi wesimbi wemhando ye z
Murwi wesimbi werudzi rweU
Sei isiri mhando yeZ kana kuti yakatwasuka asi iri mhando yeU inowanzo shandiswa muinjiniya? Kutaura zvazviri, hunhu hwemakanika emhando yeU nerudzi rweZ hwakafanana kune imwe chete, asi kunaka kwemurwi wesimbi werudzi rweU kunoratidzwa mukushanda pamwe chete kwemapombi akawanda esimbi erudzi rweU.
Kubva pamufananidzo uri pamusoro apa, zvinogona kuonekwa kuti kuomarara kwekukombama pamita imwe neimwe yemurwi wesimbi werudzi rweU kwakakura kupfuura kwemurwi wesimbi werudzi rweU (nzvimbo yepakati nepakati inochinjika zvakanyanya) mushure mekunge murwi wesimbi werudzi rweU warumwa pamwe chete.
2. Zvinhu zvesimbi zvakaumbwa nejira resimbi
