The amendment to KGS AC116\u2014covering storage tanks and pressure vessels for high-pressure gas\u2014establishes acoustic emission testing and other NDT techniques as mandatory for identifying internal defects in Type-1 pressure vessels used in compressed gas facilities. In alignment with the Enforcement Regulations of the High Pressure Gas Safety Management Act, the revised definition now includes pressure vessels employed at hydrogen fueling sites and for storing compressed gases from treatment systems. Additionally, re-inspection items will now explicitly reference inspection criteria outlined in KS B 6755 and the application of non-destructive testing limited to Type-1 vessels. Pressure vessels usually require <a href=\"https:\/\/www.korea-certification.com\/en\/kgs-factory-registration\/\"><strong>KGS factory registration<\/strong><\/a> in order to be approved for import and sale in Korea.<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.korea-certification.com\/wp-content\/uploads\/Pressure-Vessel-4-1.jpg\" alt=\"\" class=\"wp-image-24647\" style=\"width:300px\" srcset=\"https:\/\/www.korea-certification.com\/wp-content\/uploads\/Pressure-Vessel-4-1.jpg 1024w, https:\/\/www.korea-certification.com\/wp-content\/uploads\/Pressure-Vessel-4-1-300x300.jpg 300w, https:\/\/www.korea-certification.com\/wp-content\/uploads\/Pressure-Vessel-4-1-150x150.jpg 150w, https:\/\/www.korea-certification.com\/wp-content\/uploads\/Pressure-Vessel-4-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<p>The proposed acoustic emission test must be conducted three times to assess suitability.
