An imperfection or discontinuity in a material or component that may or may not affect its structural integrity or fitness for service.
A Flaw is a generic engineering term describing an imperfection, discontinuity or anomaly within a material, weld or component. Flaws may originate during manufacturing, fabrication, operation or service and include cracks, inclusions, porosity, laminations and other discontinuities. Not all flaws are defects, as many are acceptable within defined engineering acceptance criteria.
Identifying and evaluating flaws is fundamental to inspection, quality assurance and mechanical integrity programs, enabling informed decisions regarding acceptance, repair or continued service.
Flaws are typically identified using visual inspection, ultrasonic testing, radiographic testing, magnetic particle testing, liquid penetrant testing or other nondestructive examination techniques before being assessed against applicable acceptance criteria.
A Flaw is a general engineering term for an imperfection. Whether it constitutes a Defect depends upon applicable codes, standards or acceptance criteria.
