Overview
ASTM E1254-13(2023), Standard Guide for Storage of Radiographs and Unexposed Industrial Radiographic Films, provides comprehensive recommendations for the proper storage of industrial radiographs and unexposed films. Developed by ASTM International, this guide is designed to help organizations maintain the quality and longevity of radiographic images and films used in non-destructive testing (NDT) and industrial radiography. By following this standard, users can minimize image degradation, prevent physical damage, and reduce the risk of chemical instability over time.
Key Topics
-
Storage Conditions
The guide outlines optimal storage temperatures (40°F–75°F / 4.4°C–24°C) and recommends maintaining relative humidity between 30% and 60% to prevent fogging, emulsion damage, and static charges. It covers considerations for both unopened and opened film containers.
-
Residual Thiosulfate Control
Residual chemicals, especially thiosulfate left after processing, can cause permanent stains on radiographs. The guide references visual and chemical spot tests, and recommends compliance with ISO 18917 methods for thorough assessment and mitigation.
-
Enclosure Materials
Proper enclosure materials, such as chemically stable boxes and interleaving paper, are critical for protecting films from dirt, physical damage, and chemical contamination. ISO 18902 guidance is cited for enclosure selection and testing.
-
Archival Storage and Durability
Recommendations are provided for both short-term and archival storage practices, ensuring radiographs can be preserved for over 100 years when processed and stored correctly. The guide discusses strategies to minimize environmental impacts and mechanical wear over time.
-
Contaminant and Hazard Prevention
The document addresses risks from airborne particles, gases (such as sulfur compounds and acetic acid), and environmental irregularities, recommending regular monitoring and control to prevent deterioration and maintain image readability.
-
Fire Resistance
Radiographs can withstand high temperatures (up to 150°C) without loss of image quality if free of residual chemicals, but may become distorted if exposed to fire or extreme humidity.
Applications
This standard is practical and invaluable for:
- Industrial Non-destructive Testing Laboratories
Ensures preservation of critical inspection records and data integrity in radiographic testing.
- Film Archives and Records Management
Supports long-term archival of radiographic films in industrial, aviation, and manufacturing sectors.
- Quality Assurance in Manufacturing
Assists organizations in maintaining documentation required for audits, certifications, and regulatory compliance.
- Film Suppliers and Storage Facility Designers
Guides manufacturers and facility managers in designing storage spaces that comply with industrial best practices.
By applying ASTM E1254-13(2023), organizations enhance the reliability of their radiographic film storage, reduce scrap, preserve key inspection evidence, and mitigate risk of data loss or film degradation due to improper storage environments.
