1、Designation:D391210(Reapproved 2017)Standard Test Method forChemical Resistance of Coatings and Linings for Use inNuclear Power Plants1This standard is issued under the fixed designation D3912;the number immediately following the designation indicates the year oforiginal adoption or,in the case of r
2、evision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method establishes procedures for the evalua-tion of the chemical resistance of coatings and
3、linings for usein Coating Service Level I and II applications in nuclear powerplants.1.2 This test method is intended to be used as a screeningtest to evaluate coatings and linings on steel and concretesubstrates.1.3 This test method addresses two exposure intervals:(1)Short Term(Typically 5 days):S
4、uch exposures areprimarily applicable for coatings exposed to chemical splash orspill.(2)Long Term(Typically 180 days):Such exposures areprimarily applicable for linings exposed to continuous ornear-continuous chemical immersion.1.4 The values stated in inch-pound units are to be regardedas standard
