Pane zviyero zviviri zvemumiriri wedzinza: Imwe ndiro "SSPC-" yakagadzwa neUnited States muna 1985; Yechipiri ndiyo "saiti-" yakagadzirirwa neSweden muna 76, iyo yakakamurwa mamakisi mana, Nhoroondo dziri seinotevera:
Sa1 - yakaenzana neUS SSPC - SP7. Uchishandisa iyo general yakareruka bhuku, emery machira ekunakisa nzira, iyi ndiyo marudzi mana ehutsanana akaderera zvine mwero, kuchengetedzwa kwekuchengetera kungori zvishoma zviri nani pane basa rekushanda pasina kugadzirisa. Tekinoroji yemhando yeSA1 Level kurapwa: Iyo pamusoro pebasa rekushanda haigone kuve nemafuta anoonekwa, mafuta, akasara oxide, rust, yakasara pendi uye imwe tsvina. SA1 inonzi zvakare bhuku racho rebrashi kuchenesa. (kana kuchenesa kirasi)
SA2 Level - yakaenzana neUS SSSSC - SP6 Level. Iko kushandiswa kwenzira yekuchenesa sandbos yekuchenesa, iyo iri yepazasi mukurapwa kusingagumi, ndiko kuti, izvo zvinodikanwa, asi kudzivirirwa kwekuchengetera kwebhuku rekuchenesa kuti vavandudze vazhinji. Maitiro ehunyanzvi ekurapwa kweSa2: Chivako chebasa chichava chisina mafuta, tsvina, nzizi, kana kuremara (asi zvikanganiso, asi kunze kwezvinhu zvakaenzana nemamita mativi, kusanganisira zvishoma mimvuri; Hushoma hushoma hwekuderedzwa zvishoma zvinokonzerwa nekuremara kana ngura; Oxide ganda uye pendi urema. Kana paine dent mune yepakutanga pamusoro pebasa rekushanda, zvishoma ngura uye pendi icharamba iri pasi peiyo dent. SA2 giredhi zvakare inonzi zvakare commodity yekuchenesa giredhi (kana giredhi reindasitiri).
Sa2.5 - Iyi ndiyo mwero inowanzo shandiswa muindasitiri uye inogona kugamuchirwa sechinhu chinodiwa chehunyanzvi uye chiyero. Sa2.5 inodawo zvakare pedyo nekuchena chena (pedyo nekuchena kana kubva kuchena). Sa2.5 Technical Standard: Zvakafanana nechikamu chekutanga cheSa2, asi hurema hunopfurwa kusaina kupfuura 5% yemusoro wemamita, kusanganisira zvishoma mumvuri; Hushoma hushoma hwekuderedzwa zvishoma zvinokonzerwa nekuremara kana ngura; Oxide ganda uye pendi urema.
Kirasi sa3 - yakaenzana neUS SSPC - SP5, chikamu chepamusoro chekurapa muindasitiri, chinozivikanwa seyakacheneswa sekirasi yekuchenesa (kana chena class). Sa3 Level Kugadzirisa Technical Standard: Zvakafanana neSa2.5 Chikamu, asi 5% mumvuri, urema, ngura uye zvichingofanira kuvepo.
