Title:Grain Size Determination of Steels
Issuing Committee:Metals Test Procedures Committee
Scope: This classification for grain size comprises three sets of comparison charts to be used for determining grain size. These charts are presented in three categories as follows: Plate I--Untwinned grains (flat etch) Plate II--Twinned grains (flat etch) Plate IV--Austenite grains in steel (McQuaid-Ehn test or other test)【英文标准名称】:Uninterruptiblepowersystems(UPS)-Part3:Methodofspecifyingtheperformanceandtestrequirements
