ASTM A153 uye ASTM A123 zviyero zviviri zvakasiyana zvakagadziriswa neAmerican Society for Testing and Materials (ASTM International), zvakanyanya zvine chekuita nekutsanangurwa kwesimbi. Zvinotevera ndizvo zvikuru kufanana kwavo uye kusiyana:
Zvakafanana:
Nzvimbo yainangwa: Zvese zvinosanganisira kupisa-dip galvanizing, izvo zvinosanganisira kunyudza zvigadzirwa zvesimbi muzinc yakanyungudutswa kuita chivharo chekudzivirira chezingi.
Misiyano:
Inoshanda scope:
ASTM A153: Inonyanya kukodzera kupisa-dip galvanizing yezvikamu zvidiki, mabhoti, nzungu, screws, nezvimwewo zvinoshandiswa muzvigadzirwa zvakasiyana.
ASTM A123: Inonyanya kushanda kune akakura kana akakosha zvimiro, senge pombi, zvigadziriso, magadhi, zvivakwa zvesimbi, nezvimwe, zvine zvakaomesesa zvinodiwa kune yavo zinc layer.
Coating ukobvu:
ASTM A153: Iko kunowanzo kudiwa kupeta kwakatetepa uye kunowanzo shandiswa kune zvikamu zvine zvakaderera zvinodikanwa zvekudzivirira ngura.
ASTM A123: Zvinodiwa zvekupfekwa kazhinji zvakaomarara, zvinoda hukuru hwekubatisa ukobvu kuti hupe hupenyu hurefu hwekuramba kwekugara.
Nzira yekuona:
ASTM A153: Iyo nzira yekuyedza inoshandiswa iri nyore, kunyanya inosanganisira yekutarisa yekuona uye yekuyeresa ukobvu kuyerwa.
ASTM A123: Yakanyanya kuomarara, kazhinji inosanganisira kuongororwa kwemakemikari, kuongorora kwekuona, kuyerwa kwekuyerwa kwekuyerwa, nezvimwe.
Nzvimbo yekushandisa:
ASTM A153: Inokodzera zvimwe zvidiki zvikamu, mabhaudhi, nzungu, nezvimwe.
ASTM A123: Inokodzera zvivakwa zvakakura uye zvakanyanya kukosha, senge zvivakwa zvekuvaka, mabhiriji, magadhi, nezvimwe.
Pakazere, sarudzo yekuti ndeipi chiyero chekushandisa zvinoenderana nezvinodiwa zvekushandisa. Kana zvimiro zvakakura zvakabatanidzwa kana zvinoda kupikisa kwepamusoro, kupisa-dip galvanizing zvinoenderana neASTM A123 standard inowanzosarudzwa.
