New Guide for Reference Radiographs and Digital Reference Images

1. Scope

Reference radiographs assist the interpreter by replacing a word specification into a radiograph illustration of real indications in real radiographs. It is often said that one picture is worth a thousand words. This is especially true when trying to describe the appearance of certain types of discontinuities which are so often seen in radiography. There are many sets of reference radiographs. They can be grouped into 5 categories: castings, weldments, demonstration, film digitization, and visual acuity. This Guide explains the categories and how reference radiographs are used. The history of development of reference radiographs will also be included.

Reference Radiographs and Digital Reference Images are used throughout industry to create acceptance specifications. E07.02 fields many questions about the interpretation of these standards. This Guide will answer the most common questions and provide an overview to reference radiographs and their use.

The title and scope are in draft form and are under development within this ASTM Committee.
