  1. That is: [The Ministry of Construction’s announcement on the release of industry product standards “Town Gas Force” announcement is now approved by the “Urban Gas Effects” as a product standard for urban construction industry. The number is CJ/T259-2007. It will be implemented from 1st. This standard is published by the Ministry of Construction Standards Institute of Standards for the Ministry of Construction.
    The Ministry of Construction of the People’s Republic of China
    The August 21, 2007

    The standards of use of di metareteta to achieve a certain content can be used as gas, but liquefaction There is no specific standard for qi and di methal ether. You can refer to
    The local standards for “LPG Petroleum Gas ether composite fuels” in Chongqing City
    Local Standards
    Release time: 2010-2-25

    On December 1, 2009, the local standards of the “LNG Displaid Effect Curse” released by the Chongqing Municipal Quality and Technical Supervision Bureau were officially implemented. This standard specifies the technical requirements, test methods, testing rules, packaging, transportation, signs, labels, safety technical instructions, storage, filling, etc. for liquefied petroleum gas gas gas gases, etc. The security application and market specifications of fuel provide policy support.
    In recent years, with the encouragement and promotion of the national replacement of the energy industry policy, the production of di methal ether in China has made rapid progress in China, and a large number of outputs are bound to seek downstream applications. In order to meet the needs of security applications and regulating market demand in order to meet the needs of security applications and regulatory market demand, Chongqing’s liquefied petroleum ether composite fuel has introduced local standards. The local standard preparation instructions in Chongqing pointed out that after the liquefied petroleum gas mixing mixed metethyl ether, it not only conforms to the national industrial policy of the country’s replacement energy, and plays a certain energy -saving role. The affinity effect can boil the universal reorganization of liquefied petroleum gas, which can fundamentally solve the hidden dangers of accidents (carbon five) that are often dumped by users after use. The air quality after liquefied petroleum gas mixing mixed di methar ether is lower than that of the harmful gas indexes than pure liquefied petroleum gas, which has a positive role in strengthening urban environmental protection, reducing harmful gas emissions, and promoting human health and economic development.
    This is the support of relevant national policies. The technology of liquefied petroleum gas preparation of di methar ether is more mature, and the application of liquefied petroleum gas di methal ether composite fuel has been formulated under the conditions of theoretical foundation and technical achievements. Essence This standard is a technical standard for the product technology standards of liquefied petroleum gas di methar ether composite fuels within the administrative area of ​​Chongqing. It has a positive reference for the promotion and application of liquefied petroleum gas di methal ether composite fuels in the country.
