API 11D1/ISO 14310 Effort to create an industry standard began in 1994 with API taking the lead (API/C1/SC11) The work was transferred to ISO in 1995 Richard Sukup chaired a working committee under TC67/WG4 An approved standard, ISO 14310 was issued in 12-01-2001 API adopted the standard as API 11D1 in July 2002



API 11D1/ISO 14310 API adopted ISO 14310 in its entirety in July 2002 as API 11D1 API 11D1 adds an informative Annex B entitled “API Monogram licensing and marketing” Other than the API Monogram, there is no difference between the two standards



API 11D1/ISO 14310 The purpose of these standards is to allow a user/purchaser to obtain packers from any supplier/manufacturer with the assurance that validation testing and quality assurance met the same minimum requirements Supplied a common set of definitions and terms Mandated the minimum information that must be supplied with the packer upon sale to a user/purchaser



API 11D1/ISO 14310 Validation Grades V6: Supplier/manufacturer-defined (Grandfather) V5: Liquid test V4: Liquid test + axial loads V3: Liquid test + axial loads + temperature cycling V2: Gas test + axial loads V1: Gas test + axial loads + temperature cycling V0: Gas test + axial loads + temperature cycling + zero bubble acceptance criterion



API 11D1/ISO 14310 Quality Control Grades Q1: Highest level of quality control – provides revarification of chemistry and mechanical properties plus extensive NDE Q2: Intermediate level of quality control – provides increased levels of NDE Q3: Provides a minimum level of quality control that is generally consistant with the minimum level of quality used by the major manufactures of packers and bridge plugs



API 11D1/ISO 14310 ISO 14310 is currently undergoing a five year review and revision process The five year review and revision process has progressed to the FDIS stage After the revised ISO 14310 has been accepted, API 11D1 will need to begin the adopt back process to maintain the current harmony between the two standards
