Paper osayizi ngokuvumelana ISO

Namhlanje ukutshela mayelana osayizi ephepheni. Indaba yakhe iqala Ekupheleni kwekhulu XVIII-th. Ngo-1798 umlobi German kanye nososayensi, Dr. Georg Christoph Lichtenberg, encwadini ayibhalela Johann Beckmann uchaza esiwusizo futhi ngenxa yobuhle aspect ratio alinganayo empandeni sikwele angu-2.

Ngemva kweminyaka eminingana, uhulumeni waseFrance yethula umthetho ku intela ye abathengisi iphepha, ekhomba ke ubukhulu, uye ncamashi elihambisana yesimanje nezakhiwo ISO. "Grand Register" - lena ISO le A2, "papier Grand" - I-ISO B3 nokunye. ifomethi French neze kwaduma futhi abangu ukhohliwe mayelana for eyikhulu.

Ngo-1922 e-Germany ngenjongo umnotho nekghono yethulwe Din ejwayelekile 406. Lokhu mqondo obukholisayo ukuze emazweni amaningi aseYurophu futhi Asian zithatha German njengezinga elifanayo kazwelonke. Futhi kusukela ngo-1975, ngoba zonke izincwadi ezisemthethweni eNhlangano yeziZwe is lingakanani ishidi oyifakile.

Okukhishiwe amazwe amaningana aseNyakatho Melika, kuba-United States nase-Canada, kanye Japan.

Ngokusho ISO iphepha ekuqaleni yizigaba ezintathu eziyinhloko. Ngesisekelo esithathwe leaf endaweni eyodwa imitha square. Ngakho ubukhulu oluhambisana A0 format. Kukholakala ubude nobubanzi mm. Njengoba ojwayelekile, bonke abanye osayizi iphepha zinqunywa sokuhlukanisa ohlangothini elide kakhulu kuya amabili, okungukuthi, uma i-A0 (841x1189) ukuncishiselwa nengxenye, sithola 594h841. Lokhu kuyoba usayizi A1, njll

Ukuze uthole ukwaziswa isizinda uyothwala bonke osayizi ekilasini A ethebuleni.

Izakhiwo ekilasini iphepha
usayizi wephepha A0 841h1189
Usayizi wekhasi A1 594h841
A2 usayizi wephepha 420h594
A3 usayizi wephepha 297h420
A4 usayizi wephepha 210x297
A5 iphepha format 148h210
A6 usayizi wephepha 105h148
usayizi wephepha A7 74h105
Usayizi wephepha A8 52h74
iphepha format A9 37h52
Usayizi wephepha A10 26h37

Kwavulwa ikilasi eRussia ithandwa kakhulu. Ethandwa kakhulu ubhekwa A4. Wasebenzisa nsuku zonke izigidi Amahhovisi.

Kodwa e-Europe, ekukhiqizweni ayikwazi esekelwe yimuphi ngohlobo oluthile. Isizathu siwukuthi kakhulu futhi esetshenziswa kabanzi imishini yokunyathelisa ukuthi ingasebenza emhlabeni ezanelisayo zabathengi isidingo. Yingakho kukhona iphepha nezakhiwo Class B. Basuke kuchazwa ngokuthi kusho weJiyomethri phakathi A. ekilasini angomakhelwane Lokho, B1 weJiyomethri kusho phakathi A0 ne-A1. Futhi kuyafana ifomethi S-class - kuba asho weJiyomethri phakathi ngetakhiwo A no B inombolo efanayo. Lokho incwadi ebhaliwe eshidini A4, elise kahle imvilophu format C4 futhi ishidi A5 ngaphandle kwezinkinga itholakala i C5 imvilophi.

Class osayizi iphepha osayizi, B no-C
B0 1000x1414 C0 917 * 1297
B1 707x1000 C1 648 * 917
B2 500x707 C2 458 * 648
B3 353x500 C3 324 * 458
B4 250x353 C4 229 * 324
B5 176x250 C5 162 * 229
B6 125x176 C6 114 * 162
B7 88x125 C7 81 * 114
B8 62x88 C8 57 * 81
B9 44x62 C9 40 * 57
B10 31x44 C10 28 * 40

Konke lokhu izakhiwo edging okungukuthi, kuba nenkundla ishidi izincwadi isiqedile.

On emakhasini yelucwaningo ngokuvamile ukudideka ngefomethi kanye izinga. Amakilasi A, B, no-C kunoma isiphi isimo akufanele kudidaniswe iphepha futhi isigaba A +, B, B +, C, C + - futhi okuphambene nalokho. Esimweni sokuqala - lilingene ngobukhulu, okwesibili - ibanga kanye izakhiwo. Izigaba ngenhla kuchaza izinga iphepha imingcele ethile, njengengcebo ukuminyana, mhlophe, umswakama, zinyakaze conductivity, olubushelelezi, maholoholo, ukujiya, ukuqina. Ngakho, izigaba kunqunywa izinga, okungukuthi iphepha okunethezeka isigaba - kungcono A, sithola okufanele ngemali esiyikhokhayo - isigaba iphepha ekilasini iphepha umnotho - S.
