Overview

EN IEC 62976:2019/A1:2022 - Industrial non-destructive testing equipment - Electron linear accelerator - is the CENELEC-endorsed amendment to IEC 62976 that sets requirements for electron linear accelerators used in industrial non-destructive testing (NDT). The amendment was approved in 2022 and updates the original 2019/2017 text to clarify naming, technical requirements, test methods, inspection, signage, packaging, transportation, storage and accompanying documentation for NDT LINAC equipment.

Keywords: EN IEC 62976:2019/A1:2022, electron linear accelerator, industrial non-destructive testing, NDT, dosimeter, air kerma rate, signage, supplier’s declaration of conformity.

Key topics and technical requirements

• Scope and terminology
  • Defines rules of naming and classification for electron linear accelerators intended for industrial NDT.
• Technical requirements and test methods
  • Includes procedures for beam characterization and performance verification relevant to industrial X‑ray production from LINACs.
  • Example procedural detail from the amendment: place dosimeter probes in front of and 1 m from the target at the center of the X‑ray beam axis; set dosimeter to “dose”; measure three sets of time and dose during the beam test; average the results and apply the dosimeter calibration factor and air density correction factor to calculate the X‑ray beam air kerma rate.
• Inspection and documentation
  • Specifies inspection steps and required accompanying documents to support safe operation and traceability.
• Signage, packaging, transportation and storage
  • Clause titles updated: “Marking” is replaced by “Signage”, and the standard sets expectations for packaging, transport and storage of accelerators to preserve safety and condition.
• Conformity and declarations
  • “Product certification” language replaced by “Supplier’s declaration of conformity”, requiring supplier statements that include implemented product standards, inspection results, product number, production date and inspector signature.

Applications and users

• Who uses this standard:
  • Manufacturers of electron linear accelerators for industrial NDT.
  • NDT service providers using LINAC-based X‑ray systems for weld, casting and component inspection.
  • Radiation protection professionals and test laboratories performing beam calibration and dosimetry (air kerma rate measurement).
  • National standards bodies, certification and conformity assessment organizations.
• Practical value:
  • Ensures consistent naming, testing and documentation across products and markets.
  • Provides repeatable dosimetry/test procedures for verifying X‑ray beam output and radiation protection compliance.
  • Facilitates regulatory compliance, supplier declarations and safe transportation/storage practices.

Related standards and governance

• Amendment A1 is drawn from IEC 62976:2017/AMD1:2021 and was adopted as EN IEC 62976:2019/A1:2022 by CENELEC. The document was prepared by IEC/SC 45B (Radiation protection instrumentation) under IEC/TC 45 (Nuclear instrumentation). For national implementation and bibliographic references consult CENELEC/CEN member bodies.
