1、Designation:NACE TM0169/G3112aStandard Guide forLaboratory Immersion Corrosion Testing of Metals1This standard is issued under the fixed designation NACE TM0169/G31;the number immediately following the designation indicatesthe year of original adoption or,in the case of revision,the year of last rev
2、ision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers and describes the factors that influ-ence laboratory immersion corrosion tests,particularly massloss tests.These
3、factors include apparatus,sampling,testspecimen,testconditions(testsolutioncomposition,temperature,gas sparging,fluid motion,solution volume,method of supporting test specimens,duration of test),methodsof cleaning test specimens,interpretation of results,andcalculation of corrosion rates.This guide
4、also emphasizes theimportance of recording all pertinent data and provides achecklist for reporting test data.1.2 The specific evaluation of localized attack,environmen-tally assisted cracking,and effects of solution flow are notwithin the scope of this guide.1.3 This guide is intended to be used by
5、 those designinglaboratory immersion tests who may not be familiar with all ofthe variables to consider and the pitfalls that could be encoun-tered when designing and conducting this kind of testing.Itshould be used as a reference to ensure that the test will allowgeneration of data relevant to the
6、application with the mini-mum of interferences.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of
7、 the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A262 Practices for Detecting Susceptibility to IntergranularAttack in Austenitic Stainless SteelsD1193 Sp
