Overview

ISO 18119:2018/Amd 1:2021 is an important amendment to the international standard for gas cylinders made of seamless steel and seamless aluminium-alloy. This document focuses on the periodic inspection and testing of these cylinders and tubes to ensure their integrity, safety, and compliance with industry requirements. Published by ISO (International Organization for Standardization), this amendment updates inspection protocols, testing procedures, and criteria for evaluating cylinder defects, enhancing safe use and maintenance of gas storage containers.

Key Topics

  • Inspection Criteria Update
    The amendment introduces refined inspection attention on cylinders containing flammable, oxidizing, corrosive, or toxic gases to mitigate risks at the internal inspection stage.

  • Definition of Flaw Depth Ratio (a/t)
    A new term-flaw depth ratio (a/t) in percentage-is added for precise evaluation of defects relating to the cylinder wall thickness.

  • Defect and Flaw Limits
    The document specifies maximum allowable imperfection sizes for seamless steel and aluminium-alloy cylinders. It allows for certain deviations in wall thickness when defects are within acceptable severity, evaluated by ultrasonic testing techniques.

  • Corrosiveness Clarification
    Corrosiveness references human tissue rather than cylinder materials, redirecting users to ISO 13338 for related toxicological data and providing a list of gases corrosive to steel in Annex C.

  • Updated Figures and Tables
    Figures B.6 and B.7, which illustrate the maximum permissible flaw sizes in steel and aluminium-alloy cylinders, have been revised. Table A.1 footnote clarifications enhance understanding of corrosiveness distinctions.

Applications

  • Gas Cylinder Maintenance and Safety Compliance
    Industrial sectors that utilize gas cylinders-such as healthcare, manufacturing, chemical processing, and energy-rely on periodic inspection standards like ISO 18119:2018/Amd 1:2021 to maintain operational safety and meet regulatory requirements.

  • Quality Control in Production and Overhaul
    Manufacturers and inspection bodies adopt this standard to ensure gas cylinders meet durability and safety criteria before release or recertification.

  • Risk Management for Hazardous Gases
    Facilities that handle hazardous gases benefit from improved risk mitigation by applying enhanced internal inspection measures and criteria for acceptable flaw sizes.

  • Certification and Regulatory Alignment
    This amendment supports compliance with international safety regulations and harmonizes inspection methodologies between ISO and European standards organizations (CEN).

Related Standards

  • ISO/TR 22694 – Provides guidance on the evaluation of imperfection sizes and safety factors in gas cylinders.
  • ISO 13338 – Details corrosiveness related to human tissue exposure rather than materials, informing the toxicological considerations referenced in ISO 18119.
  • ISO/IEC Directives, Part 1 and Part 2 – Outlines editorial and procedural requirements for developing and maintaining ISO standards.

By adhering to ISO 18119:2018/Amd 1:2021, stakeholders involved with seamless steel and aluminium-alloy gas cylinders ensure thorough and updated inspection practices that promote safety, reliability, and regulatory compliance in gas cylinder handling and use. This standard amendment is essential for professionals aiming to maintain the highest standards in gas storage safety and operational integrity.
