Title:Instrumental Methods of Determining Surface Cleanliness (NONCURRENT Aug 2006)
Issuing Committee:Ams B Finishes Processes And Fluids Committee
Scope:This Aerospace Recommended Practice is intended as a guide toward standard practices for the determination of surface cleanliness that are applicable to field operation. Some of these methods can also be used to determine quality assurance that a surface has been properly prepared and maintained.The instrumental methods are: Wettabaility, Surface Potential Difference (SPD), Ellipsometry, and Optically Stimulated Electron Emission (OSEE). Each instrument is described with respect to measurement techniques, limitations, and advantages and types of available instruments. Elementary theoretical prinicples and examples of the use of each instrument are also given.【英文标准名称】:StandardTestMethodforShortTermCreepPerformanceofCorrugatedFiberboardContainersUnderConstantLoadUsingaCompressionTestMachine
