The establishment of the ANSI/NACE MR0175/ISO 15156 Maintenance Agency was confirmed by the ISO Technical Management Board in June 2007. A copy of the TMB Vote-Form Number: 34/2007 giving the rules of procedure for the maintenance agency can be obtained from the ISO TMB Secretariat. It is also available from the ANSI/NACE MR0175/ISO 15156 website at www.iso.org/iso15156maintenance .
