ASTM E747

ASTM E747 is a technical standard that addresses the design, manufacture, and material grouping classification of wire image quality indicators (IQI) used for radiography. It helps define how these indicators are made and organized so radiographic inspections can use consistent reference tools for image quality evaluation. For teams involved in inspection, procurement, or quality control, the standard matters because it supports uniformity, comparability, and more reliable radiographic practice.

ASTM E747 standard overview

The ASTM E747 standard provides guidance for wire image quality indicators used in radiography, with attention to their design, manufacturing, and material grouping classification. Its purpose is to support consistent indicator construction and clear grouping practices so users can select appropriate IQIs for radiographic testing applications. As an ASTM standard, it serves as a technical reference for aligning indicator characteristics with inspection expectations and quality requirements in radiographic work.

Where is ASTM E747 used?

ASTM E747 is commonly used in radiographic inspection workflows where wire IQIs are selected as part of image quality verification. It is relevant to laboratories, inspection providers, manufacturers, and quality assurance teams that rely on radiography to evaluate materials or components. The standard is especially useful when comparing indicator types, confirming material grouping, or specifying IQIs for a controlled testing program. It supports consistent use across inspection setups and reporting practices.

Practical importance of ASTM E747

In practice, ASTM E747 helps reduce variation in how wire IQIs are designed, produced, and classified. That consistency supports better compliance with inspection requirements, easier procurement decisions, and more dependable radiographic evaluation. When organizations follow a recognized standard for IQI selection and grouping, they can improve quality control, limit ambiguity in specifications, and strengthen confidence in inspection results. For many users, ASTM E747 is a practical reference for repeatable radiography support.
