Fakamatala Sivi
Ko e sivi hose rubber ('a e founga sivi paipa māma'a kasa rubber) 'oku 'a'u ai 'a e tokoni sivi fakatu'asino 'a e ZHONGXI Testing ki hono vakai'i 'o e ngaahi paipa māma'a rubber 'oku faka'aonga'i 'i he ngaahi polokalama mīniteni (hydraulic), kasa, vai, kelekele, mo e ngaahi founga fakapapitō, 'o a'u ki hono fai 'o e sivi faka-fisiolo (physical), faka-kemikale (chemical), mo faka-'ea (aging) 'o ha pasipaipa rubber 'i ha fale sivi fakatu'asino.
'Oku 'a e paipa māma'a rubber (rubber hose) ha me'alele lahi 'oku faka'aonga'i 'i he ngaahi palesi fakapapitō, tu'usi kasa, mīniteni mītini, falemotu'a, 'akau fanonganongo, mo e ngaahi ngaue faisinema. Ko e ngāue 'o e sivi hose rubber ko hono fili 'oku 'i ai 'a e paipa 'a hono malu'i 'i he ma'u 'a e mafai 'o pupulu 'i he pēsia (pressure resistance), temipiliū (temperature), kemikale (chemical resistance), mo e faka'ea 'a e taimi (aging resistance), koe'uhi 'oku mahuinga pe ha fa'ahinga paipa 'oku 'ikai sivi 'oku ma'u 'a e fa'ahita'u 'i he ngaahi 'ea mafai. 'Oku faka'aonga'i 'a e ngaahi founga sivi 'o hanga 'a e universal testing machine ki hono vakai'i 'a e tensile strength mo elongation, 'a e aging oven ki hono heat aging, 'a e burst pressure rig ki hono pressure cycling, mo e ngaahi analyzer kemikale ki hono vulcanization characteristics.
'I he 'ū sivi masani, 'oku ma'u ha sampolo paipa rubber mei he kasa 'a e potungāue 'oku ne faka'auli'i, 'oku tātaki 'a e sivi 'aki hono vakai'i 'o e hardness (Shore A), tensile strength, elongation at break, burst pressure, kink resistance, ozone resistance, fluid resistance, mo e adhesion 'i vahega (adhesion between layers).

'Oku 'i 'olunga 'a e ngaahi me'a sivi 'oku 'i ai 'a e tube swell, 'a e volume change after fluid immersion, 'a e compression set, 'a e low-temperature flexibility, mo e electrical conductivity for antistatic hoses. 'Oku ngaohi 'a e sivi kotoa pe 'i he founga 'oku tokoni'i 'e he ngaahi 'inisitiumeni sivi kuo calibrated, 'a ia 'oku mau 'i ai 'a e ngaahi founga 'o hanga 'a e data 'e ma'u 'aki ha taimi tu'u-taha (turnaround) 'oku fai 'i he 'ū 'aho 7–15 'o e nga'aofi.
