Chinese EPC Contractor for power plant would from the time of tendering of the project, determine its intention to use Chinese Codes and Standards, considering the costs involved. Normally Chinese contractor acknowledged from early in the project a requirement to adopt the specified US codes and standards for all Key Equipment. But the Chinese codes and standards would be adopted for the Non Key Equipment. This will set out as early as in Draft Project Execution Plan。

一般承接国际电站项目的中国承包商会从投标阶段确定是否在项目上使用中国规范，尤其是考虑到对其成本的影响。一般情况下，中国承包商在项目早期会在项目执行方案草稿中列明所有关键设备采用特定的美国标准，而非关键设备则允许使用中国标准规范。

Key Equipment refers to all high temperature/ high pressure equipment (eg high pressure pipework for both the boiler and turbine, the furnace and firing equipment, the boiler feed pump/s etc.), major equipment that is critical in the delivery of power (eg Turbine, Generator etc) and equipment that is critical in the protection of personnel safety (eg fire protection systems)。

关键设备指的是所有的高温/高压设备(例如锅炉和汽机的高压管道，炉膛和点火涉恶被，锅炉给水泵等)，发电中关键的主要设备(例如汽机、发电机等)以及保护人员安全设备中的关键设备(例如消防系统)。

Non-Key Equipment is normally the connecting systems (eg pipework and electrical cabling), duplicated systems where there is redundancy design into the system (eg water treatment systems where there might be 2 water treatment trains capable of treating water separately etc) and other supporting systems such as sewage treatment plant, lighting etc。

非关键设备一般指的是链接系统(例如管道和电缆)，系统中冗余设计的双重系统(例如水处理系统肯呢过有两道水处理装置能够单独进行水处理等)以及其他的支持系统例如废水处理系统、照明等。

Although the Chinese vendors selected for the project are, to a large extent, capable of producing the equipment and materials using US and internationally recognised codes and standards, doing so for non-Key Equipment would increase the costs of fabrication as it would require the vendors to change their existing production lines and technologies to be able to fabricate using non-Chinese codes and standards. This is because their existing production lines for the volume of work they carry out for projects within China are based on Chinese codes and standards。

尽管为项目选择的中国卖方在很大程度上能够使用美国和国际认可规范和标准制造设备和材料，在非关键设备使用这些标准将增加制造成本。因为满足这些标准，需要卖方更改其现存的生产线和技术，才能使用非中国规范和标准制造。这是因为，其现存的生产线是为中国境内的项目制定的工作量，是基于中国规范和标准。

In general, the equipment made in Chinese standard is much cheaper than American-Standard or international standard, such as:

一般情况下，中国标准的设备要比美标或国际标准更便宜，例如:

“Piping in China that does not meet U.S. or international codes is significantly cheaper that piping material that meets U.S. or international codes.”

“不满足美标或国际标准的中国管道比满足美标或国际标准的管道材料便宜很多。”
