The 30 FBH (Flat Bottom Hole) Resolution Block conforming to ASTM E428 standards

A resolution block is typically used in ultrasonic testing to assess the system's ability to detect and resolve small reflectors or discontinuities. The block contains flat-bottom holes of known dimensions and is employed to evaluate the sensitivity and resolution capabilities of the ultrasonic equipment.

ASTM E428 is a standard test method for the examination of ferrous and nonferrous alloys by ultrasonic examination. It covers procedures for detecting and locating discontinuities such as voids, porosity, inclusions, and other structural irregularities in materials using ultrasonic testing.

Advantages 30 FBH (Flat Bottom Hole) Resolution Block

Resolution and Sensitivity Determination: The block allows for the evaluation of resolution and sensitivity capabilities of ultrasonic testing equipment. The flat bottom holes are precisely machined to assess the smallest detectable flaw size, contributing to the instrument's overall accuracy.

Production of Amplitude Plots: The block facilitates the creation of area amplitude and distance amplitude plots. These plots help visualize and analyze the relationship between signal amplitude and distance, providing valuable insights into the performance of ultrasonic transducers.

Standardized Testing: Adhering to ASTM E428 standards ensures standardized testing procedures. This promotes consistency and comparability of results across different testing environments, making it a reliable tool for quality assurance.

Reference Standard: The block serves as a reference standard for calibrating ultrasonic testing equipment, aiding technicians in setting sensitivity levels accurately. This is essential for detecting and characterizing flaws in tested materials.

Versatility: Designed for use with normal beam transducers, the 30 FBH Resolution Block is versatile and can be employed in various applications and testing scenarios where normal beam ultrasonic testing is required.
