With　respect　to　the　test　of　pool　boiling　heat　transfer　of　highly　wetted　liquid　a　set　of　effective　test　procedures　was　proposed　and　an　experimental　study　conducted　of　R113　pool　boiling　heat　transfer　in　strict　accordance　with　the　test　procedures.　The　study　focuses　on　the　effect　of　surface　aging　and　liquid　subcooling　on　the　pool　boiling　heat　transfer　curves　and　incipient　boiling　point.　Three　abnormal　phenomena　have　been　observed　during　the　test.　In　conclusion,　from　the　perspective　of　the　boiling　heat　transfer　mechanism　of　highly　wetted　liquid　a　relevant　explanation　was　given　concerning　the　above-cited　phenomenon.
