Overview
ISO 16148:2016/Amd 1:2020 is an important amendment to the international standard addressing refillable seamless steel gas cylinders and tubes. It focuses specifically on the use of acoustic emission testing (AT) combined with follow-up ultrasonic examination (UT) for the periodic inspection and testing of these gas vessels. This amendment enhances previous methodologies and references in line with the latest safety and technical requirements.
Developed by ISO Technical Committee ISO/TC 58 and Subcommittee SC 4 in cooperation with the European standards organization CEN, this amendment aims to provide updated protocols to ensure the structural integrity and operational safety of gas cylinders used across various industries globally.
Key Topics
Scope of Testing Methods
- Utilization of acoustic emission (AE) testing as an early detection method for flaws and cracks in seamless steel gas cylinders and tubes.
- Application of ultrasonic testing (UT) as a complementary examination following AE results to precisely locate and characterize detected discontinuities.
Amendments to Reference Standards
- Replaces references of ISO 6406 with ISO 18119 regarding periodic controls and testing of gas cylinders, aligning procedures with current practices for steel and aluminum alloy gas bottles and tubes.
Inspection and Rejection Criteria
- Detailed guidelines on signal amplitude thresholds for defect detection in ultrasonic testing.
- Procedures for evaluating discontinuity length by adjusting gain and scanning directions, ensuring accurate defect characterization.
- Clear instructions on the removal from service of cylinders exhibiting critical defects, including making them unusable or conducting further examination per ISO 18119.
Technical Updates
- Revised depth ratios for notch testing to standardize defect simulation in testing protocols.
- Removal of certain previous test elements (e.g., list items e), f), and g)) to streamline inspection processes.
Applications
This amendment provides practical value to industries and stakeholders involved with gas cylinder manufacture, maintenance, and quality assurance, including:
Cylinder Manufacturers
Allowing improved in-house quality control using standardized acoustic and ultrasonic inspection methods.Inspection Agencies and Certifiers
Enabling consistent periodic testing to certify cylinders meet safety requirements before reuse or continued service.Gas Suppliers and Distributors
Ensuring their gas storage containers comply with international safety norms, reducing the risk of leaks or catastrophic failure.Regulatory Authorities
Providing updated international guidelines to harmonize inspection standards and promote safety across borders.
The combined use of AE and UT techniques as specified helps detect early-stage flaws that might otherwise go unnoticed, ensuring timely corrective action. This serves to extend the service life of cylinders while maintaining the highest levels of safety in gas storage and transportation.
Related Standards
ISO 18119 – Gas cylinders – Non-destructive periodic testing of seamless steel and aluminum alloy cylinders and tubes
This standard supersedes the older ISO 6406 and aligns directly with the testing procedures referenced in ISO 16148:2016/Amd 1:2020.ISO 11623 – Gas cylinders – Periodic inspection and testing of seamless steel gas cylinders
Provides complementary inspection guidelines relevant to gas cylinder lifecycle management.ISO 19297 – Gas cylinders – Acoustic emission inspection of seamless steel cylinders during hydraulic testing
Offers additional acoustic emission testing protocols to support safety inspections.
By adhering to these interconnected standards, organizations ensure comprehensive compliance and risk mitigation in gas cylinder inspection programs.
