1. Izinto ezibonakalayo
- Ukufana kosayizi we-particle: ukuchezuka kufanele kube ngaphansi kuka-5% (njenge-ISO 3310-1 ejwayelekile) ukuze kugwenywe into yokugeleza okufushane;
- Amandla omshini: izinga lokuguga kufanele libe ngaphansi kuka-1% (bheka i-GB/T 17431-2010) ukuze uvimbele ukuphuka ngesikhathi sokusebenza;
- Ukuzivumelanisa nokuminyana: ukuminyana kwesihlungi semidiya ekuhlanzeni amanzi kufanele kube kukhulu kuno-1.0g/cm³ ukuze kuqinisekiswe ukuvela kwenhlabathi.
2. Ukuzinza kwamakhemikhali
- Ukumelana ne-asidi ne-alkali (ibanga lokubekezelela i-pH elingu-2-12), i-antioxidant (njengevelu ye-carbon iodine ecushiwe Enkulu noma elingana no-800mg/g);
- Akukho ukuncibilika (okufana nokuqukethwe kwensimbi enzima kufanele kuthobelane nesilinganiso samanzi okuphuza e-GB 5749-2022).
3. Ezomnotho futhi esimeme
- Impilo yesevisi Inkulu noma ilingana neminyaka engu-5 (ithatha isihlabathi se-quartz njengesibonelo);
- Umjikelezo wokukhiqiza kabusha (ofana nezinga lokushisa le-carbon thermal esebenzayo lidinga ukufinyelela ku-600-800℃).
