Designation: G211 − 14 (Reapproved 2026)Standard Test Method forConducting Elevated Temperature Erosion Tests by SolidParticle Impingement Using Gas Jets 1This standard is issued under the f i xed designation G211; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, 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 is concerned with the determination ofmaterial loss by gas-entrained solid particle impingementerosion with jet nozzle type erosion equipment. This testmethod can be used in the laboratory to measure the solidparticle erosion of different materials and has been used as ascreening test for ranking solid particle erosion rates ofmaterials in simulated service environments. Erosion servicetakes place under conditions where particle sizes, chemistry,microstructure, velocity, attack angles, temperature,environments, etc. vary over a wide range. Hence, any singlelaboratory test may not be sufficient to evaluate expectedservice performance. This test method describes one wellcharacterized procedure for solid particle impingement erosionmeasurement for which interlaboratory test results are avail-able from multiple laboratories.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.
