It mandates new insulation performance tests to measure hydrogen loss over 24 hours and requires manufacturers to conduct helium leakage and vacuum tests, including room-temperature and cryogenic vacuum inspections. Thermal treatment for pressure-bearing components made of 304L stainless steel must now comply with ASME Sec. VIII Div.1 standards. Design enhancements include mandatory vacuum measurement ports and filters in insulation spaces. Exemptions have also been introduced for storage tanks located in specific regulatory zones.<\/p>\n\n\n\n<p>Feel free to contact us any time if you need assistance or have any questions regarding Korean certifications like <a href=\"https:\/\/www.korea-certification.com\/en\/kc\/what-is-kc-certification\/\"><strong>KC<\/strong><\/a>, <a href=\"https:\/\/www.korea-certification.com\/en\/kc-emc\/kc-emc-certification\/\"><strong>KC EMC<\/strong><\/a>, <a href=\"https:\/\/www.korea-certification.com\/en\/kcs\/kcs-mark\/\"><strong>KCs<\/strong><\/a>, <a href=\"https:\/\/www.korea-certification.com\/en\/kcs-ex-certification-for-explosion-proof-components\/\"><strong>KCs for explosion safety products<\/strong><\/a> or <a href=\"https:\/\/www.korea-certification.com\/en\/kgs-factory-registration\/\"><strong>KGS factory registration<\/strong><\/a>.<\/p>\n\n\n\n<p>Tel.
