1. Simplification of Requirements for Automatic Shut-Off Valves:<\/strong><\/p>\n\n\n\n

The committee has introduced substantial changes to the durability performance test for automatic shut-off valves, aimed at elevating industry standards and fortifying safety protocols. A new safety standard, grounded in product characteristics, replaces the previous practice of overly applying durability performance confirmation through cycling repetitions (250,000 times). Importantly, valves deemed unlikely to cause hazardous situations during malfunction or impaired function are now exempt from the durability test. This represents a departure from the previous requirement, allowing for a more nuanced evaluation based on valve characteristics.<\/p>\n\n\n\n

2. Relaxation of Hydrogen Quality Standards for Electrolysis Facilities:<\/strong><\/p>\n\n\n\n

Considering South Korea’s recent 10-year average lowest temperature of -11.6\u00b0C and the operational pressure in current commercial water electrolysis equipment, the committee has proposed a relaxation of restrictions on moisture concentration. Water electrolysis facilities with a rated hydrogen production pressure of 5 MPa or less are now permitted to relax the water limit to 50 \u03bcg\/g (50 ppm). This adjustment accounts for real-world operational dynamics and ensures a balanced approach to hydrogen quality standards.<\/p>\n\n\n\n

3. Clarification of Corrosion Performance Testing of Metallic Materials:<\/strong><\/p>\n\n\n\n

The committee aims to streamline standards for the exemption of corrosion resistance testing when utilizing corrosion-resistant materials. This involves a reflection of omitted conditions and acceptance criteria from specific corrosion resistance tests, including spray time with saline solution. The proposed changes seek to provide greater clarity in assessing the corrosion performance of metallic materials.<\/p>\n\n\n\n

The changes are relevant for KGS Certification<\/a><\/strong> for South Korea.<\/p>\n\n\n\n
