Scope

1.1 This document specifies the methodological requirements for eddy current array
testing of pressure equipment. The eddy current array testing conducted in accordance
with the relevant technical requirements of this document constitutes a recordable eddy
current testing.
1.2 This document applies to the eddy current array testing of surface-breaking defects
in metallic materials, components, and welded joints during the manufacture and use of
pressure equipment. The components under testing may be coated or uncoated, and their
surfaces may be flat or curved.
1.3 Eddy current array testing for near-surface defects in metallic materials,
components, and welded joints during the manufacture and use of pressure equipment
may also be conducted in accordance with this document.
1.4 For eddy current array testing of materials, components, and their welded joints
used in pressure equipment - where such testing is not explicitly specified in this
document - this document may be used as a reference, provided that process validation
demonstrates the testing requirements can be met. Eddy current array testing of support
members and structural components associated with pressure equipment may also be
conducted in accordance with this document.
