Standardization system rau cov tshuaj iav fwj

Muaj 17 tus qauv rau hom kev tshuaj xyuas thib ob. Cov txheej txheem tshuaj ntsuam xyuas no pib npog ntau yam kev tshuaj ntsuam xyuas xws li kev ua haujlwm thiab kev ntsuas ntawm ntau yam khoom ntawm cov tshuaj iav fwj. Tshwj xeeb, qhov kev ntsuam xyuas ntawm cov iav tshuaj yog hais txog ISO cov qauv thiab ntxiv cov dej tsis kam tshiab. , Kev tshawb pom ntawm alkali thiab acid tsis kam muab ntau dua, ntau dua thiab kev tshawb nrhiav txoj hauv kev rau kev txheeb xyuas cov tshuaj lom neeg ruaj khov kom hloov tau ntau yam khoom ntawm cov tshuaj iav fwj rau cov tshuaj ntawm cov khoom sib txawv thiab ntau npaum li cas. Ua kom ntseeg tau qhov zoo ntawm cov tshuaj iav fwj thiab yog li ua kom cov tshuaj zoo yuav ua lub luag haujlwm tseem ceeb. Tsis tas li ntawd, txoj kev tshawb nrhiav kom pom cov txiaj ntsig ntawm leaching ntawm cov ntsiab lus tsis zoo tau raug ntxiv los ua kom muaj kev nyab xeeb ntawm cov tshuaj hauv cov tshuaj iav fwj. Cov txheej txheem tshuaj xyuas cov iav fwj tshuaj yuav tsum tau muab ntxiv thiab txhim kho. Piv txwv li, txoj kev sim rau alkali- tiv taus tev ntawm ampoules, txoj kev sim rau kev tawg quab yuam thiab txoj kev sim rau kev tiv thaiv kev poob siab, thiab lwm yam. txhua yam muaj kev cuam tshuam tseem ceeb rau kev ua tau zoo thiab kev siv cov tshuaj iav fwj.

The third type of basic standards consists of 3 items. Among them, the "Classification of Pharmaceutical Glass Bottles and Their Test Methods" refer to ISO 12775-1997 "Classification of Glass by Composition and Test Methods for Normal Mass-produced Glass". There is a clear definition of the bottle composition classification and its test method standards, which are formulated to distinguish the classification of glass materials from other industries. The other two basic standards respectively limit the harmful elements of lead, cadmium, arsenic, and antimony in the composition of glass materials to ensure the safety and effectiveness of all kinds of medicines.
