【摘要】:1ThispartofISO12944dealswiththeclassificationoftheprincipalenvironmentstowhichsteelstructuresare,exposed,andthecorrosivityoftheseenvironments.It—definesatmospheric-corrosivitycategories,basedonmassloss(orthicknessloss)bystandardspecimens,anddescribestypicalnaturalatmosphericenvironmentstowhichsteelstructuresareexposed,givingadviceontheestimationofthecorrosivity;—describesdifferentcategoriesofenvironmentforstructuresimmersedinwaterorburiedinsoil;—givesinformationonsomespecialcorrosionstressesthatmaycauseasignificantincreaseincorrosionrateorplacehigherdemandsontheperformanceoftheprotectivepaintsystem.Thecorrosionstressesassociatedwithaparticularenvironmentorcorrosivitycategoryrepresentoneessentialparametergoverningtheselectionofprotectivepaintsystems.2ThispartofISO12944doesnotdealwiththeclassificationofthoseenvironmentsthatconsistofspecialatmospheres(forexamplethoseinandaroundchemicalandmetallurgicalplants).
