Description

Octagonal Standard Block

The octagonal pattern is used as an aid in determining the direction of magnetic fields for detecting discontinuities in ferrous metals.

Benefits

• It helps in the process of identifying the magnetic field, its intensity and direction.
• It allows for sensitivity analysis of the product being applied in the inspection.
• With the discontinuities facing downwards, there will be simulation of subsurface discontinuities.
• With the discontinuities facing upwards, there will be simulation of surface discontinuities.

Compliance and Standards

• ASME BPVC
• ASTM E709
• ASTM E1444
