Igeragezwa rya Hydrostatike, rizwi kandi nka hydro test, ni inzira yo kugerageza silindiri ya gaze kugirango imbaraga zivemo. Iki kizamini gikozwe mubwoko bwinshi bwa silinderi nka ogisijeni, argon, azote, hydrogène, dioxyde de carbone, imyuka ya kalibrasi, imvange ya gaze, hamwe na silinderi idafite kashe cyangwa isudira hatitawe kubintu bya silinderi. Ikizamini cya hydro mugihe cyemeza ko silinderi imeze neza kandi ikwiriye gukomeza gukoreshwa mugihe cyagenwe.
Gupima Hydro ya silinderi ni itegeko ukurikije amabwiriza yatanzwe n’ishami rishinzwe umutekano wa peteroli n’ibisasu (PESO). Amashanyarazi yumuvuduko mwinshi agomba kwipimisha hydro buri gihe cyimyaka 5 cyangwa bikenewe bitewe na silinderi. Amashanyarazi amwe amwe nka CNG na gaze yuburozi akenera kwipimisha kenshi, nka buri myaka 2.
Mugihe cya hydro, silinderi ihatirwa kumuvuduko wikizamini, mubisanzwe inshuro 1.5 cyangwa 1.66 umuvuduko wakazi. Ibi bigenzura ibintu byoroshye, bigenda byangirika mugihe hamwe no kuzuza inshuro nyinshi. Silinderi irashyirwaho igitutu hanyuma igacika intege kugirango irebe ko igaruka mubipimo byayo byumwimerere mugihe ntarengwa cyo kwihanganira. Igeragezwa rya hydro mugihe cyemeza ko silinderi igifite elastique ihagije kugirango ikoreshwe neza.
Uburyo bwo gupima hydro burimo kuzuza silinderi hafi y'amazi adashobora kugabanuka, ubusanzwe amazi, no kuyasuzuma kugirango imeneke cyangwa impinduka zihoraho mumiterere. Amazi arakoreshwa cyane kuko hafi ya yose atavogerwa kandi azaguka kubwinshi cyane. Niba gaze yumuvuduko ukabije yarakoreshejwe, gaze irashobora kwaguka inshuro zigera ku magana ingano yacyo, bikagira ibyago byo gukomeretsa bikomeye. Umuvuduko wikizamini uhora urenze cyane igitutu cyo gukora kugirango utange intera yumutekano. Mubisanzwe, 150% byumuvuduko wimikorere birakoreshwa.
Silinderi ishyirwa imbere yikoti yamazi ifite ingano izwi. Ikoti y'amazi ihujwe na burette ya Calibrated ipima ihinduka ryubunini bwamazi imbere yikoti. Silinderi noneho ihindurwamo amazi kugeza igeze kumuvuduko wikizamini. Umuvuduko ufatwa mugihe runaka, mubisanzwe amasegonda 30 cyangwa arenga. Muri iki gihe, silinderi yaguka gato kandi ikuraho amazi ava mu ikoti yerekeza kuri burette. Ubwinshi bwamazi yimuwe yerekana kwaguka kwa silinderi mukibazo. Nyuma yo gufata umwanya, igitutu kirarekurwa kandi silinderi igasezerana mubunini bwumwimerere. Amazi yimuwe asubira mu ikoti avuye kuri burette. Itandukaniro riri hagati yisomwa ryambere kandi ryanyuma rya burette ryerekana kwaguka guhoraho kwa silinderi.
Kwaguka guhoraho ntigomba kurenga 10% yo kwaguka kwose. Niba ikora, bivuze ko silinderi yatakaje bimwe byoroshye kandi ishobora kuba yarateje ibice cyangwa inenge bibangamira ubusugire bwayo. Amashanyarazi nkaya agomba gukurwa muri serivisi agasenywa. Ikizamini cya hydro nacyo kigenzura niba cyatembye harebwa igabanuka ryumuvuduko mugihe cyo gufata cyangwa ibibyimba byose biva kuri silinderi.
Ibisubizo by'ibizamini bya hydro byanditswe kandi bigashyirwaho kashe kuri silinderi hamwe nitariki yo kwipimisha hamwe numero iranga ikigo cyemewe. DOT isaba ko hydrostatic retesting and re-qualification ikorwa nabakozi biyandikishije bemejwe na DOT kandi bahawe nomero iranga Re-testers yemewe (RIN) nubuyobozi bwa DOT nubushakashatsi bwihariye (RSPA). Igeragezwa rya Hydro ryemeza ko silindiri ya gaze itekanye kandi yizewe kubyo igenewe.
