Qhov tseeb, cov neeg kho tshuab muaj pes tsawg leeg thiab tshuaj lom neeg cov yam ntxwv ntawm cov hlau yog tib yam thiab nws yog tus tsim khoom ntawm tus qauv uas yog qhov sib txawv tseem ceeb. ASTM, American Society for Testing and Materials, tsim cov qauv uas txhais cov kev txwv thiab cov kev txwv ntawm cov khoom lag luam thiab cov txheej txheem ntawm kev sim cov khoom. ASME, American Society of Mechanical Engineers, qhia cov khoom siv los tsim thiab tsim cov khoom tshwj xeeb.
