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 |     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。

二 |     Variety discount store Family Dollar recently initiated multiple recalls on products ranging from over-the-counter drugs to toothpaste sold at regional chains in nearly two dozen states.The company first issued an announcement Oct. 5, which was published Oct. 10 by the U.S. Food and Drug Administration, alerting Family Dollar shoppers of a voluntary recall on "over-the-counter drugs and medical devices" that had been "stored outside of labeled temperature requirements by Family Dollar and inadvertently shipped" to some of its stores from June 1 through Sept. 21, 2023.The wide range of recalled items includes cold medicine, pain relievers, mouthwash, moisturizer, vitamins and more. Affected products were sold in 23 states from June 1 through Oct. 4, 2023."To date, Family Dollar has not received any consumer complaints or reports of illness related to this voluntary recall," the company statement read. "This recall is being conducted out of an abundance of caution."Family Dollar did not immediately respond to ABC News' request for comment.Click here to see the full list of products included in the recall and SKU information."Family Dollar has notified its affected stores asking them to check their stock immediately and to quarantine and discontinue the sale of any affected product," the company statement continued.Customers who purchased any of the recalled items are able to return them to the purchase location without a receipt for a refund.A full list of recalled items, as well as the states impacted, can be found on the FDA's website.Family Dollar experienced a similar issue earlier this spring when it voluntarily recalled seven Advil products that it said were also stored at the wrong temperature.。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。

三 | 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）。
