AB  - The  European  X-ray  Free  Electron  Laser  (XFEL)  is  in  operation  at  DESY.  The superconducting XFEL linac will produce pulsed electron beam at an  energy of 17.5 GeV. The linac   consists   of   768   superconducting   niobium   1.3 GHz   nine   cell cavities and 96 superconducting  magnet  packages  assembled  in  96  cryomodules.  Each  cryomodule  is  12  m  long  and  includes  a  2 K  helium  II  bath  circuit  for  the  cavities and 5/8  and  40/80 K  thermal radiation shields. Before being installed in the  XFEL linac tunnel all cryomodules were tested in the Accelerator Module Test Facility (AMTF ) . In  this  paper  methods  and  results  of  static  and  dynamic  heat  load  measurements  of  all  XFEL cryomodules  are  reported.  A  comparison with  first  integral  heat  load measurements  in  the  XFEL linac  is given
