ASTM A179 tuubbada tuubbada birta

Kala soocidda geedi socodka wax soo saarka birta ee birta ah guud ahaan, geedi socodka wax soo saarka ee tuubooyinka birta aan kala go 'lahayn ayaa loo qaybin karaa laba nooc: sawir gacmeed iyo duuban oo kulul. Geedi socodka wax soo saarka ee tuubbooyinka birta ee qulqulaya ee birta-qabow ayaa guud ahaan ka dhib badan marka loo eego duulista kulul. Tuubbooyinka tuubbada tuubada waa in marka hore lagu gudajiro saddex-duub oo is daba joog ah. Ka-soo-kabashada kadib, baaritaanka cabirka waa in la sameeyaa. Haddii aysan jirin wax jawaab celin ah oo dusha sare ah, tuubbada wareega waa in lagu gooyaa mashiin go 'ah oo loo jaro meel ku dhow hal mitir dherer. Ka dib geli geedi socodka dunida. Gargaarku wuxuu u baahan yahay inuu kaxeeyo dareeraha aashitada. Markaad jeexjeexid, fiiro gaar ah u yeelo haddii ay jirto tiro aad u badan oo ka mid ah dusha sare ee dusha sare. Haddii ay jirto xaddi badan oo ka mid ah xumbada, waxay ka dhigan tahay in tayada birta birta aysan buuxin karin heerarka u dhigma. Muuqaal ahaan, tuubooyin bir-bir oo qabow ayaa ka gaaban tuubooyinka birta kulul ee kulul. Furuuruca derbiga ee qulqulka birta-qabow ee birta ee qulqulaya ayaa guud ahaan ka yar tuubooyinka birta kulul ee kulul, laakiin dusha sare waxay umuuqataa mid ka dhalaalaya tuubooyin bir-qaro ah, oo dusha sarena aad uma qaro. Waa wax aad u adag, mana jiraan burbur badan oo dhexroor ah.
