ISO publishes China-led standard on commissioning and testing ship ballast water systems
En breve
The International Organization for Standardization (ISO) has recently published ISO 23817:2026, a China-led standard setting commissioning and testing procedures for electrolytic ballast water management systems on ships, Chinese outlets reported on October 9. Experts from the United States, Germany, Canada, Switzerland, Norway, Denmark and other countries took part in drafting it. The standard requires systems to run for at least 60 minutes and a discharge sample volume of at least 1 cubic metre.

The International Organization for Standardization (ISO) has recently published an international standard on commissioning and testing procedures for electrolytic ballast water management systems (BWMS), Chinese outlets reported on October 9. China News Service, citing the website of the State Administration for Market Regulation, gave the standard's number as ISO 23817:2026. The standard was led by China, with experts from the United States, Germany, Canada, Switzerland, Norway, Denmark and other countries taking part in drafting it. [ 1 , 2 , 4 , 5 ]
According to the reports, the standard sets technical requirements for commissioning and testing electrolytic ballast water management systems. It requires systems to run for no less than 60 minutes and a discharge sampling volume of no less than 1 cubic metre, and calls for compliance verification for two classes of organisms: those 50 micrometres and larger, and those between 10 and 50 micrometres. The reports said this is meant to ensure systems meet the discharge standards of international conventions, and that the standard gives shipowners, shipyards, equipment manufacturers and industry regulators worldwide a unified, scientific commissioning and testing procedure and basis for acceptance. [ 1 , 4 , 5 ]
The reports said alien organisms carried in ships' ballast water are one of the main pathways of marine biological invasion and pose a serious threat to marine ecological security. Ballast water management systems are the key equipment for killing these organisms, and their effectiveness depends both on the design performance of the product and on the level of on-site commissioning after installation, according to the reports. [ 1 , 4 , 5 ]
China has so far led the drafting of three international standards related to ballast water management systems, covering key stages including system design and commissioning, the reports said. They said these standards play an important role in curbing the spread of harmful aquatic organisms across sea areas through ballast water and support global marine environmental protection. [ 1 , 4 , 5 ]
CLS and IT Home attributed their reports to CCTV News, and 36Kr carried a short summary citing CCTV News. Yicai published only the headline. [ 1 , 2 , 3 , 5 ]
