Ibyumba bisukuye

Isukuicyumbaigomba kuba yujuje ibipimo by’umuryango mpuzamahanga wita ku bipimo ngenderwaho (ISO) kugirango bishyirwe mu byiciro.ISO yashinzwe mu 1947 kugirango ishyire mubikorwa amahame mpuzamahanga kubintu byoroshye byubushakashatsi bwa siyansi nubucuruzi, nkimirimo yimiti, ibikoresho bihindagurika, nibikoresho byoroshye.Nubwo uyu muryango washinzwe ku bushake, amahame yashyizweho yashyizeho amahame shingiro yubahwa n’imiryango ku isi.Uyu munsi, ISO ifite ibipimo birenga 20.000 ibigo bishobora kwifashisha.

Mu 1960, Willis Whitfield yateguye kandi ategura icyumba cya mbere gisukuye.Ibyumba bisukuye byateguwe kandi byashizweho kugirango birinde inzira n'ibirimo ibintu byose bidukikije hanze.Abantu bakoresha icyumba nibintu bipimwe cyangwa byubatswemo birashobora kubuza icyumba gisukuye kutuzuza ibipimo byacyo byisuku.Igenzura ryihariye rirasabwa gukuraho ibyo bintu bitera ibibazo bishoboka.

Umuntu ukoresha icyumba nibintu byageragejwe cyangwa byubatswe mucyumba arashobora kubuza icyumba gisukuye kutuzuza ibipimo by’isuku.Igenzura ryihariye rirasabwa gukuraho ibyo bintu bitera ibibazo bishoboka.

Muri Reta zunzubumwe za Amerika 209 (A gushika D), ubwinshi bwibice bingana kandi birenga 0.5µm bipimwa muri metero kibe yumuyaga, kandi iyi mibare ikoreshwa mugushira icyumba gisukuye.Iri jambo ryemewe naryo ryemewe muri verisiyo ya 209E iheruka ya Standard.Reta zunzubumwe zamerika zikoresha reta ya 209E imbere mugihugu.Ibipimo biheruka ni TC 209 yo mumuryango mpuzamahanga wita ku bipimo.Ibipimo byombi bishyira mucyumba gisukuye hashingiwe ku mubare w’ibice biboneka mu kirere cya laboratoire.Ibyumba bisukuye byashyizwe mu byiciro FS 209E na ISO 14644-1 bisaba gupima ibipimo byihariye byo kubara no kubara ibyumba bisukuye cyangwa urwego rw’isuku ahantu hasukuye.Mu Bwongereza, Standard Standard yo mu Bwongereza 5295 ikoreshwa mu gushyira ibyumba bisukuye.Ibipimo ngenderwaho bigomba gusimburwa na BS EN ISO 14644-1.

ikintu nka zeru yibanze.Umwuka w'icyumba gisanzwe ni icyiciro 1.000.000 cyangwa ISO 9.

Ibyumba bisukuye mubyumba bipima urwego rwisuku mukubara ingano nubunini bwibice kuri cubic yumwuka.Umubare munini nka "urwego 100 ″ cyangwa" icyiciro 1000 ″ bivuga FED_STD-209E, kandi ukerekana umubare wibice bingana na 0.5 µm cyangwa binini byemewe kuri metero kibe yumuyaga.Igipimo nacyo cyemerera interpolation, birashoboka rero gusobanura urugero "icyiciro 2000."

Imibare mito yerekeza kuri ISO 14644-1, igaragaza logarithm ya cumi yumubare wibice 0.1 µm cyangwa binini byemewe kuri metero kibe yumuyaga.Kurugero, kurugero rwa ISO icyiciro cya 5 cyisuku gifite byibuze 105 =Urwego 100.000(ibice kuri m³).

Byombi FS 209E na ISO 14644-1 bifata isano-yo guhuza ibiti hagati yubunini bwibice hamwe nubunini bwibice.Kubera iyo mpamvu, ntakintu nkicyerekezo cya zeru.Umwuka w'icyumba gisanzwe ni icyiciro 1.000.000 cyangwa ISO 9.
