Overview
SIST EN ISO 11117:2020/kFprA1:2026 specifies the requirements for the design, construction, and testing of valve protection caps and guards for gas cylinders. This Amendment 1 to ISO 11117:2019 focuses on updates to thread dimensions, tolerances, and specific test protocols related to valve caps and guards, improving international harmonization and safety for gas cylinder fittings.
Complying with this standard is essential for manufacturers, suppliers, and inspection authorities involved in the production or maintenance of gas cylinders, particularly in ensuring the safe transport, handling, and storage of pressurized gases.
Key Topics
Valve Protection Caps and Guards
The standard details requirements for the protective covers and guards used on gas cylinder valves to prevent mechanical damage.Design Updates
Amendment 1 introduces revised technical drawings and dimensional updates for North American threads, ensuring compatibility and interchangeability in global markets.Testing Requirements
The document clarifies when drop tests are required following changes to valve guard physical configurations, ensuring protection effectiveness.Tolerance Specifications
Updated tables specify the required tolerances for threaded components, helping manufacturers and inspectors achieve a consistent and safe product.Documentation Changes
The amendment modifies specific terminology and reporting requirements for the documentation of valve guard designs.
Applications
Industrial Gas Supply
Used in manufacturing, healthcare, and research sectors, gas cylinders require robust valve protection to prevent accidents during transport and storage.Cylinder Inspection and Recertification
Inspection agencies reference this standard to assess compliance of cap and guard fittings, especially when component modifications are made.Global Supply Chain Compliance
Manufacturers exporting or importing gas cylinders rely on this standard to ensure their products meet safety and dimensional requirements recognized internationally.Product Design and Development
Engineers and technical teams consult the standard’s dimensional tolerances and thread profiles to design components fully compatible across regions.

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
