新版强制国标发布，将提升车用压缩天然气产品质量_我的网站

一 |     China will step up efforts to strengthen ecological conservation during the 2026-2030 period as it continues to pursue green modernization, according to a recently issued development plan.
The plan, jointly issued by the Ministry of Ecology and Environment, the Ministry of Natural Resources and other departments, said China aims to steadily improve the quality of its ecosystems, enhance ecosystem diversity, stability and resilience, and better safeguard the country's ecological security.
The plan also sets specific targets for the period, including keeping the proportion of land area covered by protected areas at no less than 18 percent of the country's total land area and raising the Ecological Quality Index (EQI) to 86.5. It also calls for increasing the soil and water conservation rate to above 74 percent and raising the forest coverage rate to 25.8 percent.
It also outlines tasks to further optimize the ecological spatial configuration, advance ecosystem protection and restoration, and comprehensively strengthen biodiversity conservation.
China has continued to strengthen ecological conservation and environmental protection. The country's landmark Ecological and Environmental Code, set to take effect this Saturday, marks another major step in these efforts, providing stronger legal support for sustainable and environmentally friendly development.
。    市场监管总局（国家标准委）近日批准发布《车用压缩天然气》强制性国家标准，将自2027年8月1日起实施。本次标准修订旨在提升产品质量、保障使用安全、促进贸易公平。一是技术指标持续健全，新增甲烷值和互换性要求，明确车用压缩天然气的甲烷值应不小于65，与欧洲标准的要求保持一致，当甲烷值小于70时，加气站须在经营场所显著位置向社会公示具体数值。同一地区的车用压缩天然气应能互换使用，确保不同气源的天然气在切换使用时不影响发动机性能和安全性。二是试验方法全面升级，新增或调整了高位发热量、总硫、硫化氢、二氧化碳、氧气、水露点、水含量等项目的检测方法，其中甲烷值计算方法新增丙烷爆震指数法（PKI-MN法）作为仲裁试验方法，与国际标准接轨。三是取样与判定规则不断完善，新增“取样”独立章节，取样点设在车用压缩天然气交接点。判定规则明确检验结果达到全部质量要求视为合格，不符合时应复测。该标准的发布实施将有效规范我国压缩天然气产品质量管控，促进车用压缩天然气行业高质量发展，保障天然气汽车正常运行，持续提升人民群众出行安全水平。（央视新闻）。
