Iifomathi zamaphepha (icandelo II: DIN-B kunye neDIN-C)

Kwingeniso endiyenzileyo ngaphambili Iifomathi zephepha (icandelo I: I-DIN-A), sathetha ngokweenkcukacha malunga nemilinganiselo yolu hlobo lwefomathi, kodwa sashiyeka ukuba sixoxe nge I-DIN-B kunye I-DIN-C. Azisetyenziswa kancinane kwisiseko semihla ngemihla kodwa kufuneka sazi ngobukho bazo kwaye sazi isiseko sazo ukuba kunokwenzeka sibhenele kuzo kumsebenzi wethu.Kumyili okanye oyilayo kubalulekile ukuba nolu hlobo lobuchule bokwenza izinto. ulwazi.

Ngokuqhelekileyo zisetyenziselwa ukubiza kunye nokuqaphela imilinganiselo ye iimvulophu kunye neengxowa.

Iifomati zothotho lwe-B zihlala zinkulu kunothotho lwe-A. Kwaye iifomathi zothotho lwe-C ziphakathi kwezimbini ezidlulileyo. Njengefomathi zika-A, zohlulwe zibe ziifomathi ezincinci ezilishumi ngokulungelelana ngokuxhomekeke kubungakanani beemilimitha zecala ngalinye.

Kwabo basebenza kakuhle kwizibalo, umlinganiselo umi ngolu hlobo lulandelayo:

Imilinganiselo echanekileyo ye iifomati de la B uthotho Ziyintsingiselo yejometri yamaxabiso anxulumene nefomathi ehambelanayo kwaye iphezulu ngokukhawuleza kuthotho A.

Umzekelo:

B0 = 1000 × 1414 mm2 = ?(841·1189) × ?(1189·1682) mm2, iziphumo ezivela kwiifomathi A0 (841 × 1189 mm2) kunye 2A0 (1189 × 1682 mm2).

Imilinganiselo ye C uthotho Ziintsingiselo yejometri ye iifomati yenani elifanayo loluhlu A kunye no-B, badla ngokubiza imilinganiselo yemvulophu.

Umzekelo:

C0 = ?(841·1000) × ?(1189·1414) mm2 = 917 × 1297 mm2.

Iifomathi ze-C zinobudlelwane obuthe ngqo kunye nefomathi ye-A, umzekelo iphepha le-A4 elidityanisiweyo lihambelana namacala amafutshane angena kwimvulophu ye-C5 kwaye ihlanganiswe kabini ingena kwimvulophu ye-C6.
