Raws li lub ntsiab lus tseem ceeb ntawm kev ntim tshuaj pleev ib ce, qhov zoo thiab kev nyab xeeb ntawm cov hmoov compacts ncaj qha cuam tshuam rau kev ruaj ntseg ntawm cov khoom, lawv cov txiaj ntsig, thiab cov neeg siv khoom noj qab haus huv. Cov kev pabcuam kuaj kev tshaj lij tsom mus rau lub cev thiab cov khoom siv kho tshuab, tshuaj lom neeg kev nyab xeeb, ntsuas microbiological, thiab kev ua haujlwm ntawm cov hmoov ntim cov ntaub ntawv, txhawm rau txheeb xyuas lawv cov kev ua raws li cov cai hauv tebchaws thiab cov qauv kev lag luam. Kev ntsuam xyuas qhov tseem ceeb suav nrog kev txheeb xyuas cov khoom siv, kev tsiv hlau hnyav, kev sib khi, kev ua haujlwm ntev, thiab kev txwv microbial, ua kom cov khoom zoo thiab kev nyab xeeb thaum khaws cia, kev thauj mus los, thiab siv, thiab muab cov chaw tsim khoom nrog lub hom phiaj thiab kev tswj xyuas cov ntaub ntawv zoo.
Cov khoom kuaj
1. Kev soj ntsuam qhov pom thiab qhov ntev: qhov tsis xws ntawm qhov chaw (xws li khawb, npuas, impurities, xim sib txawv), tag nrho qhov ntev, cov khoom haum clearances, luam ntawv zoo (kev sau npe raug, xim, adhesion), thiab lwm yam.
2. Kev Ntsuas Lub Cev thiab Kev Ua Haujlwm: Lub hau qhib thiab kaw qaug zog, lub lens cuam tshuam tsis kam, pob khawm durability, hmoov puff / txhuam kho firmness, zuag qhia tag nrho poob tsis kam, deg hardness, abrasion tsis kam, thiab lwm yam.
3. Chemical Safety Testing: Testing for migratable heavy metals (lead, cadmium, mercury, arsenic, antimony, etc.), phthalate plasticizers, polycyclic aromatic hydrocarbons (PAHs), tshwj xeeb aromatic amines, tag nrho cov volatile organic compounds (TVOCs), formaldehyde tso tawm dawb, thiab .
4. Kev txheeb xyuas cov khoom siv: Kev txheeb xyuas qhov zoo ntawm cov ntaub ntawv yas (piv txwv li, PP, ABS, PMMA), muaj pes tsawg leeg thiab thickness ntawm cov hlau plating, cov khoom siv lens tsom, thiab kev tshuaj ntsuam xyuas cov nplaum.
5. Sealing and Barrier Performance Testing: Test case sealing (kev tiv thaiv cov dej ntws), lens -to- case sealing, thiab tag nrho cov dej tsis kam (rau ya raws- cov hmoov rhiab heev).
6. Microbiological Indicators Test: Tag nrho cov kab mob suav, tag nrho cov pwm thiab cov poov xab suav, thermotolerant coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, thiab lwm yam.
7. Kev Ntsuas Kev Ua Haujlwm: Lens duab pom meej thiab distortion, sib nqus hloov quab yuam thiab tuav lub zog, hmoov compact grid stability, thiab hmoov dispensing yooj yim simulation sim.
8. Kev ntsuam xyuas kev ntseeg ib puag ncig: kev kub siab thiab cov av noo ruaj khov, tsis tshua muaj siab ntev, ntsuas kub caij tsheb kauj vab, ntsuas kev laus lub teeb (ultraviolet, xenon teeb), thiab lwm yam.
