This Standard specifies the minimum requirements for the inspection, repair and alteration of in-service boilers, pressure vessels, piping, safety equipment, and associated safety controls (hereafter referred to as pressure equipment), and gives guidance in the execution of such activities. Guidance is included for the inspection of ancillary equipment such as structures. This Standard also specifies the requirements for the initial inspection after installation and prior to commissioning. The inspection flow diagram (see Figure 1.1) illustrates the various types of inspection covered by this Standard.This Standard provides information to facilitate grounds for agreement between interested parties, and the establishment of uniform minimum requirements for in-service inspections, including inspection intervals and procedures, to assist in assuring safe and economic operation. Information is provided on mechanisms of deterioration, the assessment of defects, and the assessment of fitness for service of pressure equipment.No rules can be written in sufficient detail to cover all aspects of the inspection of in-service pressure equipment. The owner is responsible for ensuring that the extent and frequency of inspection is appropriate and adequate for the continued safe operation of the pressure equipment. This may require the seeking of expert advice.Duty of Care is now prescribed by Occupational Health and Safety Legislation. This Standard does not supersede such Duty of Care, but is intended to complement and contribute to it.
