ASTM A193
Baaxadda
Markii hore la ansixiyay 1936, qeexitaankan si weyn ayaa looga faa'iidaystaa batroolka iyo codsiyada dhismaha kiimikada. Heerarka ASTM-ku wuxuu dabooshaa birta daawaha ah iyo qalabka birta ah ee aan la isku dhejin ee loogu talagalay adeegga heerkulka sare. Tilmaamahan waxaa ku jira xirmooyin loogu talagalay in lagu isticmaalo weelasha cadaadiska, valves, flanges, iyo qalabyada. In kasta oo, walxahan inta badan laga heli karo garoonnada dunta (UNC), haddii loo isticmaalo codsiyada dhaqanka, dunta waxaa lagu qeexaa 8 threads halkii inch (tpi) ee dhexroorka ka sarreeya hal inji.
Hoos waxaa ku qoran kooban aasaasiga ah ee dhowr ka mid ah darajooyinka guud. ASTM A193 waxay dabooshaa tiro tilmaamo kale oo heersare ah oo aan lagu sheegin tilmaantan oo ay ku jiraan B5, B6, iyo B16.
