Tsis ntev los no, National Toy Standardization Technical Committee tau teeb tsa cov kws tshaj lij los tshuaj xyuas cov qauv tsim nyog hauv lub tebchaws "Kev Nyab Xeeb Kev Nyab Xeeb rau Twist Tsheb" uas tau tsim los ntawm Lub Tsev Haujlwm Saib Xyuas Khoom Ua Si Hauv Lub Xeev.
Tom qab ua tib zoo tshuaj xyuas, pawg kws tshaj lij tau pom zoo tias tus qauv tsim cov kev xav tau rau lub cev kev nyab xeeb kev ua haujlwm, flammability, cov ntsiab lus ntawm kev tsiv teb tsaws, kev ua haujlwm ruaj ntseg, thiab hluav taws xob kev nyab xeeb ntawm cov khoom siv tsheb sib tw. Cov kev cai lij choj tau mus txog qib siab hauv tsev, thiab daim ntawv thov thiab kev ua haujlwm yog nyob rau hauv txoj kab nrog qhov tseeb ntawm cov khoom siv tsheb sib tw. Nws yog tus sawv cev zoo heev thiab ua haujlwm tau zoo, ua tiav cov ntsiab lus ntawm kev tshawb fawb thiab kev siv tau. Cov qauv ntawm cov qauv no ua rau qhov sib txawv hauv lub tebchaws thiab cov qauv kev lag luam rau cov khoom siv tsheb sib tw, thiab yog qhov tseem ceeb tshaj plaws rau kev ntsuam xyuas cov khoom zoo ntawm cov tsheb twist, standardizing enterprise ntau lawm, thiab xyuas kom meej cov khoom zoo thiab kev nyab xeeb. Tam sim no, tus qauv tseem tab tom tos kev pom zoo thiab xav tias yuav tsum tau ua tiav sai sai.
