What is ISO 16826 - Ultrasonic testing for discontinuities perpendicular to the surface about?
ISO 16826 is an international standard that covers ultrasonic testing for discontinuities perpendicular to the surface, ensuring product consistency, durability and longevity in metallic materials.
ISO 16826 specifies defines the principles for tandem- and longitudinal-longitudinal-transverse (LLT) wave examination for the detection of discontinuities perpendicular to the surface. The tandem- or LLT-examination should be used for the detection of planar discontinuities with a distance to the surface greater than 15 mm.
ISO 16826 has been prepared for the examination of metallic materials with a thickness between 40 mm and 500 mm with parallel or concentric surfaces. It can, however, be used for other materials and smaller thicknesses provided special measures are taken.
Who is ISO 16826 - Ultrasonic testing for discontinuities perpendicular to the surface for?
ISO 16826 on Ultrasonic testing for discontinuities perpendicular to the surface applies to:
- Testing houses and labs using ultrasonic equipment
- Non-destructive testing agencies
- Quality assurance services
- Simulation testing services
Why should you use ISO 16826 - Ultrasonic testing for discontinuities perpendicular to the surface?
Ultrasonic testing (UT) is a non-destructive test method for detecting cracks and defects in components and materials using sound waves. It can also be used to measure the thickness of metallic materials, such as a wall thickness of a pipe, sheets, rods and components.
ISO 16826 provides users guidance on tandem examination including, time base adjustment, setting of sensitivity, determination of examination zones, DGS-diagram, corrections of sensitivity and more, enabling the detection of defects and flaws in metallic materials.
ISO 16826 provides users guidance on LLT examination including, time base adjustment and determination of discontinuity depth, setting of sensitivity, determination of examination depth, DGS diagrams for LLT-examination, enabling the detection of discontinuities in metallic materials.
With obedience and compliance to ISO 16826, users can assess discontinuities to determine surface flaws and irregularities to ensure product quality, performance and longevity in industrial testing applications.
