Abstract：Hydrogen energy，asacrucial componentof thenewenergysystem，playsasignificantrole inreducing greenhouse gas emissions and achieving the goals of carbon peak and carbon neutrality as soon aspossble.Hydrogen embritlementcan happen when metal materialsare exposed to high-pressure hydrogen environments.Therefore，the storageandtransportationofhydrogenhavebecomeacriticallink inthedevelopmentof the hydrogen energy industry chain.This paper studies the standards forhydrogen environment compatibility tests of metallic materials exposed to high-pressure hydrogen at home and abroad.It focuses oncomparingand analyzing the differences in various testing methodsathomeandabroad，andsummarizes theshortcomingsofnational standards interms ofthe basis forevaluating testresults.Thefindingsprovidevaluablereferences forhydrogenenvironmentcompatibilitytestsofmetallic materials exposed to high-pressure hydrogen.
