About This Item
ASTM E1114 is the standard test method for determining the size of Iridium-192, Cobalt-60, and Selenium-75 industrial radiographic sources. It provides a technical basis for measuring source size in radiographic equipment, which matters because source dimensions can affect image quality, inspection consistency, and compliance checks. For organizations that use sealed radioactive sources in industrial radiography, this ASTM standard supports more reliable evaluation and procurement decisions.
ASTM E1114 standard overview
The ASTM E1114 standard addresses how to determine the size of specific industrial radiographic sources: Iridium-192, Cobalt-60, and Selenium-75. Its role is to give users a consistent test method for evaluating source dimensions in a controlled and repeatable way. That makes it a useful technical reference when comparing sources, verifying product characteristics, or supporting quality control activities. As an ASTM standard, it is intended to improve consistency across testing and documentation practices.
Where is ASTM E1114 used?
ASTM E1114 is commonly used in industrial radiography settings where Iridium-192, Cobalt-60, or Selenium-75 sources are part of inspection workflows. It is relevant to source manufacturers, radiography service providers, and quality teams that need a dependable way to measure or verify source size. The standard may also support incoming inspection, supplier evaluation, and documentation for radiographic source specifications. In practice, it helps align testing methods across facilities and equipment users.
Practical importance of ASTM E1114
The practical value of ASTM E1114 is consistency. When source size is measured using a recognized ASTM method, teams can compare results more confidently and reduce ambiguity in technical records. That is important for procurement, acceptance testing, and internal quality control, especially when source characteristics affect radiographic performance. Using ASTM E1114 can also support compliance efforts by giving organizations a clear reference for source-size determination and related documentation.
