Updated Certification Standards for Hydrogen and Gas Tanks/ Cylinders in Korea
30. January 2025The Ministry of Trade, Industry, and Energy (MOTIE) in Korea has implemented new standards for high-pressure gas storage and related equipment under the Korean Gas Safety Corporation (KGS) codes. Effective January 2025, the revisions aim to enhance safety, clarify compliance protocols, and align with international regulations. Products categorized under KGS AC113, AC417, and AC211 require KGS factory registration for approval to be imported and sold in Korea.
The updated KGS AC113 standard, applicable to tanks mounted on vehicles, introduces expanded material options by permitting austenitic stainless steel for pressure-bearing parts. Testing protocols now include inspections for safety valve retention time, while improved insulation and pressure monitoring designs bolster transport safety. Under KGS AC417, standards for hydrogen cylinders used in fuel cell vehicles now synchronize with international criteria, refining inspection, labeling, and terminology for “hoop-wrapped cylinders.” The KGS AC211 code corrects clause references, clarifies testing methods, and incorporates ISO standards for welded gas cylinders. These updates provide clearer safety guidelines and ensure compliance with both local and global standards.
