ISO 23802:2026

Overview

ISO 23802:2026 sets out the requirements and recommendations for the periodic inspection and testing of gas cylinders-specifically seamless tubes, composite tubes, and large tubes that are permanently mounted in a frame. This standard is essential for ensuring the safety and continued serviceability of gas tube modules and assemblies used in the storage and transport of compressed gases. The scope includes composite tubes with either metallic or non-load-sharing liners, seamless steel tubes, associated mounting frames, and equipment installed in battery vehicles, Multiple Element Gas Containers (MEGCs), and large tube modules.

Routine inspection per ISO 23802:2026 helps identify material degradations, mechanical wear, operational damage, and equipment non-conformities that may compromise safe operation. The standard is applicable to owners, manufacturers, inspection bodies, and maintenance providers operating within the compressed gas industry.

Key Topics

• Inspection Preparation: Comprehensive guidance for preparing tubes and assemblies for inspection. This includes requirements for safe depressurization, proper identification of all elements, and the gathering of conformity documents.
• Inspection Procedures: Detailed processes for inspecting both modular assemblies with or without disassembly, covering frames, fixation of elements, saddles, mounts, panels, and fire protection systems.
• Testing Methods: Endorses non-destructive testing (NDT) methods, such as ultrasonic testing and acoustic emission testing, aligning with referenced ISO standards for both Type I (seamless) and Type II-IV (composite) tubes.
• Equipment Inspection: Covers inspection and maintenance for valves, manifolds, piping, fasteners, and associated safety and emergency devices. Includes leak checks, corrosion assessment, and operational checks for all critical components.
• Repair and Replacement Protocols: Offers requirements for the repair and replacement of components, ensuring compatibility with original design and specification, as well as the documentation requirements for any modifications.
• Inspection Reporting and Recordkeeping: Mandates detailed inspection reports and records for traceability, including all pertinent inspection data, maintenance actions, and component history.

Applications

ISO 23802:2026 is used in a variety of practical settings within the compressed and liquefied gas industry, including:

• Battery Vehicles and MEGCs: Ensuring periodic safety inspections of permanently mounted gas tube assemblies in vehicles designed for bulk gas transport.
• Large Gas Tube Modules: Facilitates regular inspection and maintenance of containers with high-capacity tubes-critical for industrial gas supply, energy storage, and distribution networks.
• Manufacturing and Assembly: Assists manufacturers and assemblers in complying with regulatory requirements for gas container modules.
• Authorized Inspection Facilities: Provides inspection bodies with standardized protocols for conformity assessment, defect documentation, and safe operational approval.
• Asset Owners and Operators: Guides owners of gas tube modules in fulfilling legal obligations for periodic inspection and recordkeeping, helping to maximize asset life and ensure regulatory compliance.

By applying ISO 23802:2026, stakeholders enhance the safety, reliability, and traceability of gas transport modules, reduce the risk of accidents, and support regulatory compliance at national and international levels.
