Sharaxaad
Farsamooyinka korantada ku shaqeeya ee awoodda sare leh waxaa laga sameeyaa irbad tayo sare leh oo loo yaqaan 'coke coke' oo ah maaddada ceyriinka ugu weyn, waxaana lagu sameeyaa sameynta, dubista, uur yeelashada, garaafaynta iyo farsamaynta farsamada. Waxaa si ballaaran loogu isticmaalaa foornooyinka qaansoleyda korantada ku shaqeeya sida walxaha wax lagu kala qaado.

Faahfaahinta
Tusmooyinka jireed iyo kiimiko ee koronto-wadayaasha awooda sare leh iyo ibta naaska waxaa loola jeedaa YB / T 4090-2015
Tilmaamaha ku saabsan koronto garaafka
1. Korontada waa in lagu keydiyaa meel nadiif ah, qalalan, shoog iyo shilalka shilalka.Waa in la qalajiyaa isticmaalkeeda.
2.Marka aad isku xireyso ibta naaska, ku nadiifi godka hawo cadaadis leh, ka dibna ku dheji ibta naaska si taxadar leh adiga oo aan dhaawaceynin madaxa.
3.Befor caarada korantada hawo ciriiri ah marka labada koronto ay u jiraan 20-30mm.
4.Marka elektaroodyadu ay ku xirmaan qulqulkaha, waa in si buuxda loogu adkeeyo lakabka la caddeeyay in farqiga u dhexeeya labada koronto uu ka yar yahay markaa 0.005mm.
5.Si looga fogaado jajabka korantada, fadlan ka fogow baraha qalabka wax lagu baro.
6. Si aad uga fogaato jajabka korantada, dhig birta anise-ga ah ee qaybta hoose oo dhig dhig yar qaybta sare.
