Overview
EN ISO 11117:2019/prA1 is an important amendment to the international standard ISO 11117:2019, which covers the design, construction, and testing of valve protection caps and guards for gas cylinders. Published by CEN and developed under ISO/TC 58/SC 2, this amendment provides updated guidance and requirements to ensure the safety, reliability, and compatibility of protective components used on high-pressure gas cylinders. Valve protection caps and guards are critical for safeguarding valves against mechanical damage during handling, transport, and storage, which directly impacts operational safety across various industries.
Key Topics
The amendment introduces several key updates and clarifications relevant to manufacturers, safety engineers, and inspection bodies in the gas cylinder sector:
- Updated Dimensional Requirements: Revised figures and tables set out the dimensions and tolerances for typical North American thread profiles, ensuring compatibility and standardization for cylinder neck rings and valve guards.
- Clarified Design Envelope: Enhanced language specifies required external dimensions and schematic arrangements for valve guards, facilitating accurate technical drawings and mitigating risk of assembly errors.
- Revised Testing Requirements: Clear criteria for when drop tests (impact resistance tests) must be repeated, particularly in cases where modifications are made to the physical features of protected valves.
- Evaluation of Design Changes: Distinguishes between changes that require further testing (such as modification of valve features) and those that do not (like changes to handwheel, material, or connections).
- Editorial and Structural Improvements: Refinement of list structures, terminology, and references throughout the document to improve clarity and usability.
Applications
This amendment to ISO 11117:2019 is widely applicable to organizations involved in the design, production, maintenance, and inspection of gas cylinders, specifically those using or supplying valve protection devices. Key areas of application include:
- Manufacturers of Gas Cylinder Accessories: Ensures valve protection caps and guards are designed and tested to meet updated international requirements, supporting global trade and regulatory compliance.
- Gas Distribution and Logistics: Provides standards for equipment compatibility and safety during the transport and storage of high-pressure gas cylinders.
- Industrial Gas Suppliers: Facilitates the safe supply and use of industrial, medical, and specialty gases by minimizing risks of valve damage.
- Inspection and Certification Bodies: Offers clear criteria for conformity assessment, enabling consistent inspection and certification practices in line with updated international standards.
Adhering to the latest requirements of EN ISO 11117:2019/prA1 improves operational safety, aids in regulatory compliance, and reduces liability by ensuring robust protection of gas cylinder valves under various real-world conditions.
Related Standards
The following standards are closely related to EN ISO 11117:2019/prA1 and may be relevant for organizations working in the compressed gas and pressure equipment sectors:
- ISO 11117:2019: Gas cylinders - Valve protection caps and guards - Design, construction and tests (parent standard)

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters
