Introduction

• The first edition of API 579 produced by API CRE
  FFS Task Group is issued in 2000 and becomes the
  de facto international Fitness-For-Service (FFS)
  Standard for pressure containing equipment in the
  refining and petrochemical industries
• ASME forms Post Construction Committee (PCC) to
  develop standards for in-service fixed equipment
• FFS effort started under ASME PPC, existing API
  CRE Task Group continues to develop the next
  edition of API 579, many committee members are
  serving on both committees
• In order to streamline development efforts, pool
  resources, and promote widespread regulatory
  acceptance, API and ASME agree to form a joint
  committee to produce a single FFS standard that
  can be used for pressure-containing equipment for
  all industries
