5.1.2 Verification is to be based on performance standards which are subject to approval by LR for each critical system/element derived from the risk assessment.

5.1.3 LR will produce a project-specific in-service Verification Plan for each case. This will cover the following key aspects:
  1. Review and approval of critical elements.
  2. Review and approval of performance standards derived from risk assessment.
  3. Review and approval of the Owner/Operator’s Inspection and Maintenance Plan.
  4. Monitoring the execution of the Owner/Operator’s Inspection and Maintenance Plan.
  5. Examination of the installation and records at intervals and frequency commensurate with level of development of Owner/Operator’s Inspection and Maintenance Plan.
  6. Examination of design, construction, installation and commissioning of any modifications.

5.1.4 LR will develop the Verification Plan for in-service activities to suit the Owner/Operator’s methodology for inspection and maintenance. This will detail the examination work associated with each critical system/element.

5.1.5 LR’s review of the Owner/Operator’s Inspection and Maintenance Plan will include:
  1. Management objectives and structure.
  2. Management systems.
  3. Planning/scheduling/reporting.
  4. Data evaluation and determination of inspection intervals.
  5. Methods of inspection/testing/monitoring.
  6. Competency, resourcing and training of personnel used for inspection and testing.
  7. Procurement, calibration and maintenance of maintenance and test equipment.
  8. Software systems for inspection and maintenance planning and recording.
  9. Quality Assurance and Quality Control.

5.1.6 Following review of the Owner/Operator’s Inspection and Maintenance Plan, LR will develop a Verification Plan with an appropriate level and depth of examination to confirm that the elements identified as critical in relation to class continue to meet the approved performance standards. LR verification activities may include review of records, audit of procedures and activities of inspectors acting for the Owner/Operator, sample checks and physical examination of the installation, as appropriate.

5.1.7 Any revision of the Owner/Operator’s Inspection and Maintenance Plan for the critical elements is to be carried out in consultation with LR and is subject to approval by LR.

5.1.8 The Owner/Operator is to co-operate with the requirements of the Verification Plan, and is to provide all necessary information and access for LR to carry out its verification tasks.

5.1.9 Verification activities will take place on a continuous basis as determined in the Verification Plan. Verification status reports will be generated by LR at appropriate intervals (usually annual) to facilitate renewals of any National Administration statutory certificates and maintenance of class.

5.1.10 The Verification Plan will also include a system for reporting and recording of conditions of class that will indicate clearly the timescales for any remedial actions.

5.1.11 Based on the findings of the Verification activities, LR reserves the right to increase or decrease the level and frequency of activities.

5.1.12 Class may be suspended or withdrawn, if deemed necessary, at the discretion of the Classification Committee.
