SA1 - zofanana ndi US SSPC - SP7. Pogwiritsa ntchito burashi wamba yosavuta, njira yopukutira ya Emery, iyi ndi mitundu inayi yaukhondo yotsika mtengo, kuteteza kotentheka ndikokhabwinoko kuposa zopangira. Muyezo waukadaulo wa Sa1 Level: Pamwamba pa ntchitoyo sayenera kukhala mafuta, mafuta, otsalira oxidi, utoto wotsalira ndi dothi lina. SA1 amatchedwanso Shopushing Sulong. (kapena kuyeretsa kalasi)

SA2 mulingo - zofanana ndi US SSPC - SP6 mulingo. Kugwiritsa ntchito njira yotsuka mchenga, yomwe ndi yotsika pamsana, ndiye kuti, zofuna zonse, koma kutetezedwa kwa zokutira kuposa kutsuka kwa bukuli kuti zisinthe. Muyezo waukadaulo wa mankhwala: Malo ogwirira ntchito azikhala opanda mafuta, dothi, dzimbiri, utoto, ndi zinthu zina zakunja (kuphatikiza mithunzi yaying'ono), kuphatikiza mithunzi yochepa; Kuchuluka kocheperako koyambira chifukwa cha chilema kapena dzimbiri; Kusimba khungu la oxide ndi zilema za utoto. Ngati pali dent pamalo oyambilira a ntchito, dzimbiri ndi utoto ndi utoto zimatsalira pansi pa dent. SA2 kalasi imatchedwanso katundu woyeretsa (kapena kalasi ya mafakitale).

SA2.5 - Uwu ndiye mulingo womwe umagwiritsidwa ntchito m'mafakitale ndipo amatha kuvomerezedwa ngati njira yaukadaulo ndi muyezo. SA2.5 imatchedwanso kuyerekeza kuyeretsa (pafupi ndi loyera kapena yoyera). SA2.5 Muyezo: chimodzimodzi ndi gawo loyamba la sa2, koma chilema chimakhala chosaposa 5% ya pamwamba pa mita imodzi, kuphatikizapo mthunzi pang'ono; Kuchuluka kocheperako koyambira chifukwa cha chilema kapena dzimbiri; Kusimba khungu la oxide ndi zilema za utoto.

Kalasi S3 - Yofanana ndi US SSPC - SP5, ndiye gulu lapamwamba kwambiri m'makampaniwo, limadziwikanso kuti ndi gulu loyeretsa loyera (kapena gulu loyera). SA3 Level Processiwer Standard: chimodzimodzi ngati SA2.5 pamlingo wa Sa2.5, koma 5% mthunzi, chilema, dzimbiri ndi izi zimayenera kukhalapo.
