商品的自由流通是建立单一市场的基石，实现商品自由流通的机制就是CE标志，这个机制建立在欧盟各国之间避免产生新的贸易壁垒、相互认可和技术标准协调之上。为了使指令里规定的产品基本要求更具有可操作性，由各成员国负责将本国的标准与之协调一致。并且协调标准是否符合指令精神的讨论机制和标准修改机制也随之建立起来。由于指令里规定的要求是各国都要遵守的要求，所以这些要求应该是公认的防范安全隐患或其他危害的最低纲领。为了在实践中得到贯彻，欧盟进规定产品是否符合指令规定的基本要求的可靠的评估方式，即人们俗称的CE认证。

●欧盟的法律、法规和协调标准不仅数量多，而且内容十分复杂，因此取得欧盟指定机构帮助是一个既省时、省力，又可减少风险的明智之举;
●获得由欧盟指定机构的CE认证证书，可以最大程度地获取消费者和市场监督机构的信任;
●能有效地预防那些不负责任的指控情况的出现;
●在面临诉讼的情况下，欧盟指定机构的CE认证证书，将成为具有法律效力的技术证据;
●一旦遭到欧盟国家的处罚，认证机构将与企业共同承担风险，因此降低了企业的风险。

燃气具指令90/396/EEC
一个产品在投入欧盟市场销售或投入使用之前，产品标记CE标志，往往涉及多个欧盟指令的要求，燃气具产品也不例外。比如，燃气烧烤炉和燃气灶具必须满足燃气具指令（GAD）的要求；使用市电的电子控制燃气烤箱必须满足燃气具指令（GAD）、低电压指令（LVD）和电磁兼容性指令（EMC）的要求；使用市电的电子控制燃气热水器和电子控制燃气锅炉必须满足燃气具指令（GAD）、低电压指令（LVD）、电磁兼容性指令（EMC）和锅炉能效指令（BED）。
所以，一款燃器具产品的CE认证要考察以下三个问题：
1. 产品适用哪个或哪几个欧盟指令？
2. 这些欧盟指令规定的产品评估模块和由评估模块组成的产品评估程序是怎样的？
3. 产品需要分别符合哪些欧盟协调标准才可以当然地认为分别满足了这些欧盟指令的要求？
