Amsterdam - Beijing - Philippines

Hi. My parents will be arriving in PEK from Amsterdam (SAS Airline) at 11:55 and have a connecting flight to Philippines with PAL airlines at 12:55, just an hour connection time. Is this enough? I have read some reviews, some say it takes very long time queing in the understaffed immigration and other security inspection, while others say its just ok. I know it depends on the load of passengers in that day. But considering its in the middle of the day..? Does anyone know what terminal does the PAL (Philippine Airlines) is using?
Your words would be a great help. Thank you.
