API 579-1 / ASME FFS-1- 2007 is a standard jointly published by the American

Petroleum Institute          (API) and the American Society for Mechanical
Engineers (ASME). The API          579-1/ASME FFS-1 Standard covers a wide range
of flaw types and damage          mechanisms, including:

                      Corrosion


          > General metal loss

          > Local metal loss

          > Pitting


                      Crack-like flaws

                      Brittle fracture

                      Damage due to hydrogen          embrittlement (HIC and

SOHIC)

                      Weld misalignment and          shell distortion

                      Dents and gouges

                      Creep damage and creep          crack growth

                      Fire damage

A joint API & ASME   standard was being developed circa. 2005 based on papers from ASME PV &   Piping Conference in Denver, that year. I see that ASME now has an E-Book   product titled "FFS-1 - 2007 Fitness for Service". But no hard-bound copy   seems to be available.

  Is "FFS-1 - 2007 Fitness for Service" the outcome of the joint work of   API/ASME and the latest edition of API RP 579? Has "FFS-1 - 2007 Fitness   for Service" taken effect and superseded RP 579 at this time?
