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
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.
