Non-destructive testing – Characteristics of focal spots in industrial X-ray systems – Part 2: Edge method with hole or disk type test objects (ISO 32543 2:2026); German version EN ISO 32543 2:2026
Abstract
This document specifies a method for the measurement of effective focal spot dimensions > 0,2 μm of X-ray systems by means of the edge method applied to digital images taken from hole type or disk type test objects if no phase contrast is observed. The imaging quality and the resolution of X-ray images depends highly on the characteristics of the effective focal spot, in particular its size and two-dimensional intensity distribution as seen from the detector plane. This document specifies procedures for determining the effective size (dimensions) of standard, mini and micro focal spots of industrial X-ray tubes for users in applications where the pin hole method according to ISO 32543-1 is not applicable. The method specified in this document is applicable for measurement and long-term monitoring of focal spot sizes without a pin hole camera.
