Gusukura ibyumba bisukuye

Muri Amerika, kugeza mu mpera z'Ugushyingo 2001, hifashishijwe ibipimo ngenderwaho bya 209E (FED-STD-209E) kugira ngo bisobanure ibyumba bisukuye. Ku ya 29 Ugushyingo 2001, aya mahame yasimbuwe no gutangaza ISO Ibisobanuro 14644-1. Ubusanzwe, icyumba gisukuye gikoreshwa mu gukora cyangwa mu bushakashatsi bwa siyansi ni ibidukikije bigenzurwa bifite urugero rwinshi rw’umwanda, nk'umukungugu, mikorobe zo mu kirere, uduce duto twa aerosol, hamwe n’umwuka w’imiti. Mu buryo busobanutse neza, ubwiherero bufite igipimo cy’umwanda cyagenzuwe, kikaba kigaragazwa n’umubare w’ibice kuri metero kibe ku bunini bwagenwe. Mubidukikije bisanzwe mumijyi, ikirere cyo hanze kirimo miriyoni 35 kuri metero kibe, microne 0,5 z'umurambararo cyangwa munini, bihuye nicyumba cya ISO 9 gisukuye kurwego rwo hasi rwicyumba gisukuye. Ibyumba bisukuye bishyirwa mubikorwa ukurikije isuku yumuyaga. Muri Leta zunze ubumwe za Amerika 209 (A kugeza D), umubare wibice bingana cyangwa birenga 0.5mm bipimwa muri metero kibe 1 yumuyaga, kandi iyi mibare ikoreshwa mugutondekanya ibyumba bisukuye. Iyi metric nomenclature nayo yemerwa na verisiyo ya 209E iheruka. Ubushinwa bukoresha federasiyo 209E. Ibipimo bishya ni TC 209. Umuryango mpuzamahanga wita ku bipimo ngenderwaho.Ibipimo byombi bishyira mu byumba bisukuye ukurikije umubare w’ibice biri mu kirere cya laboratoire. Ibyumba bisukuye mubyumba bisukuye FS 209E na ISO 14644-1 bisaba ibipimo byihariye byo kubara no kubara kugirango ubone urwego rwisuku rwicyumba gisukuye cyangwa ahantu hasukuye. Mu Bwongereza, Standard Standard 5295 ikoreshwa mu gushyira ibyumba bisukuye. Ibipimo bizasimburwa vuba na BS EN ISO 14644-1. Ibyumba bisukuye bishyirwa muburyo ukurikije umubare nubunini bwibice byemewe kuri buri kirere cyumwuka. Umubare munini nka "Icyiciro 100" cyangwa "Icyiciro 1000" bivuga FED_STD209E, byerekana umubare wibice bya mm 0,5 cyangwa ubunini bunini bwemewe kuri metero kibe yumuyaga.
