Scope

GB/T 36589-2018 is the English-translated version of 铸件工业计算机层析成像（CT）检测.

GB/T 36589-2018 covers the inspection of castings by X-ray industrial computed tomography (CT). It sets out terms and definitions, general requirements, equipment requirements, the inspection process, the evaluation of results, test records and reports, and file management.

Defined terms include computed tomography, spatial resolution and density resolution, described as main technical indicators of a CT system.

The standard refers to the national guides and methods for industrial CT, covering system selection, performance testing, image measurement and general requirements, together with radiation protection rules and health requirements for radiation workers.

It applies to detecting defects in castings and to measuring and comparing their structural dimensions. It was issued on 17 September 2018 and has applied since 1 April 2019.

3 Terms and definitions

The following terms and definitions as defined in GB/T 34365 apply to this document.

3.1 Computed tomography (CT)

A detection method for reconstructing a physical feature distribution map of an object from a projection data.

3.2 Spatial resolving power / spatial resolution

A measure of the ability of the CT system to identify and distinguish the geometric details of an object being measured.

Note: Spatial resolving power/spatial resolution is one of the main technical indicators of CT systems. Spatial resolving power is usually in mm, and spatial resolution is usually in lp/mm.

3.3 Density resolving power / density resolution

Under certain conditions, the CT system recognizes the ability of a specified size region to differ from the surrounding region in an object.

Note: Density resolving power/density resolution is one of the main technical indicators of CT systems. Density resolving power is usually in mm. […]
