The standard of material selection for the main components of household solar energy has a more obvious feature, which refers to a number of relevant national standards when making specific provisions for the main components. Appliance "reporter rough statistics in accordance with the specification of national standard draft that referenced 40 items. There are many codes in the selection standard of solar energy main components, which can effectively guide enterprises to produce according to the existing standards and restrict business behavior. Zheng Ruicheng, chief engineer of the national solar water heater quality supervision and Inspection Center (Beijing) said.

之所以引用这么多的国家规范，与标准涉及到主要部件类别较多有关，这也大大增加了规范制定的难度。张立峰表示，最初对主要部件进行的分类要比审定稿中的详细，对于要不要进行这样详细的分类也是制定过程中争论的焦点。据《电器》记者了解，家用太阳能主要部件选材标准》最初是依照集热部件、水箱内胆、保温水箱隔热体、不锈钢保温水箱外壳、支架、水箱密封件、辅助电加热、管材管件、保温管路和紧固件等进行分类，审定时已经简化为集热器、贮水箱、支架和管路4个部分，而且在起草过程中该分类也曾经进行过多次调整。一位知情人士透露：规范规定得越详细，行业门槛往往也就越高，底规定到何种难度应该符合现在行业发展的现状，能够给行业留出发展的余地，所以企业都很关注这一点。

The citation of so many national norms is related to the standard involving more major components, which also greatly increases the difficulty of standard setting. Zhang Lifeng said that the initial classification of the main components was more detailed than the finalization, and the focus of the debate was to make such a detailed classification. According to the "electrical" reporter, the standard for selecting the main components of the household solar energy is first classified according to the classification of the collector parts, the tank inside the tank, the insulation of the thermal insulation tank, the shell of the stainless steel insulation tank, the support, the seal of the water tank, the auxiliary electric heating, the pipe fittings, the insulation pipe and the fastener. The collector, storage tank, support and pipeline are 4 parts, and in the process of drafting, the classification has also been adjusted many times. The more detailed the specification is, the more the industry threshold is, the more difficult it should be to meet the current industry development, and to give the industry room for development, so enterprises are very concerned about this.

希望《家用太阳能主要部件选材标准》能够起到指引的作用，首先告知企业基本的规范有哪些。张立峰表示，目前太阳能热水器不锈钢水箱厂家数量多、素质高低不一，有些小企业甚至连需要遵循的规范都找不全。

It is hoped that the selection standard of household solar energy main components can play a guiding role. First, inform the basic norms of enterprises. Zhang Lifeng said that the current solar water heater stainless steel tank manufacturers are many, the quality is different, some small enterprises even even need to follow the standard can not be found.

当然，除了引用已有标准外，家用太阳能主要部件选材标准》也有一些具有太阳能热水系统特色的规定。20%~30%内容是只有太阳能热水系统才会涉及的张立峰说。比方，对于密封胶圈的规定，就很好地弥补了目前太阳能热水系统国家标准的空白。但是由于密封胶圈国家标准正在制定中，待制定完成并实施后，家用太阳能主要部件选材标准》关于密封胶圈的规定将参考密封胶圈国家标准进行修订。

Of course, in addition to citing existing standards, there are also some regulations on solar energy hot water system with criteria for selecting solar energy main components. 20%~30% content is only related to solar hot water system, Zhang Lifeng said. For example, the regulations for sealing aprons make up for the gaps in the current national standards of solar water heating systems. However, as the national standard of sealing apron is being formulated, after completion and implementation, the standard for the material selection of the main components of the household solar energy will be revised according to the national standard of sealed aprons.

针对企业指导性强

Strong guidance for enterprises

电器》记者了解到家用太阳能主要部件选材标准》GB/T19141-2003家用太阳热水系统技术条件》国家规范的配套规范，对GB/T19141-2003家用太阳热水系统技术条件》扩展。GB/T19141-2003家用太阳热水系统技术条件》太阳能热水系统国家规范体系中最为重要的规范，对家用太阳能热水系统做出较为全面的规定。虽然行业规范体系中不乏这样全面的国家规范，但是一直未能出台一部对家用太阳能热水系统主要零部件的选材做出统一规范的国家规范。张立峰说，现行规范中，对性能做出规定的规范比拟多，家用太阳能主要部件选材标准》则更多地对安全性和寿命进行要求。而水箱内胆的卫生平安性和内腐蚀性、支架的机械强度和耐候性都成为《家用太阳能主要部件选材标准》关注的焦点。

The reporter understands the standard of material selection for the main components of household solar energy, GB/T19141-2003 domestic solar hot water system technical conditions of the national standard of the supporting standard, GB/T19141-2003 domestic solar hot water system technical conditions for expansion. GB/T19141-2003 domestic solar hot water system technical conditions "the most important standard in the national standard system of solar water hot water system, making a more comprehensive provision for household solar hot water system. Although there is no lack of such a comprehensive national standard in the industry standard system, a national standard for the selection of the main components of the household solar hot water system has not been issued. Zhang Lifeng said that in the current norms, more specifications for performance are compared, and the selection criteria for the main components of the household solar energy are more required for safety and life. The health safety and internal corrosion of the tank, the mechanical strength and weatherability of the stent have become the focus of the standard for the selection of the main components of the household solar energy.

作为审定该标准的行业专家之一，郑瑞澄表示，家用太阳能主要部件选材标准》规定比拟全面，其中对于平安性的规定十分重要，企业应当加以重视。同时，还表示，这一规范对企业生产太阳能热水系统所用零部件资料提出具体要求，其中的检验规则主要针对推销件，对于企业检测外购材料具有较强的指导意义，但是对于检验机构来讲，规范的可操作性并不强。

As one of the industry experts to determine the standard, Zheng Ruicheng said that the standard of material selection for the main components of the household solar energy is more comprehensive, which is very important to the safety regulations, and the enterprises should pay attention to it. At the same time, it also indicates that this specification puts forward specific requirements for the materials used in the production of solar water hot water system. The inspection rules are mainly aimed at the selling parts. It has a strong guiding significance for the enterprises to test the external purchase materials, but the specification is not strong for the inspection agencies.

随着太阳能产业规模日益扩大，行业的分工正向专业化和精细化发展。一位业内人士对《电器》记者表示，目前，几乎每一家太阳能热水系统生产企业都需要外购零部件，但是太阳能热水系统主要零部件供应商素质良莠不齐，市场运行机制不规范，零部件质量不过关已经成为制约太阳能产业规范发展的一大问题。

With the expansion of the scale of solar energy industry, the division of labor is developing professionally and meticulous. At present, almost every solar hot water system production enterprise needs spare parts, but the quality of the main component suppliers of the solar hot water system is uneven, the market operation mechanism is not standard, the quality of the parts has become a restriction on the solar industry standard. A big problem of development.

据介绍，该规范对家用太阳能热水系统主要部件的选材原则、技术要求、试验方法和标识包装均做出较为详细的规定。可以预见，家用太阳能主要部件选材标准》获得有关部门批准并正式实施后，必将对规范太阳能热水系统零部件选材，提高太阳能热水系统的使用寿命、可靠性和稳定性发挥积极的引导作用。

According to the introduction, the specifications of the main components of the household solar hot water system, technical requirements, test methods and logo packaging are made more detailed provisions. It is foreseeable that the material selection standard for the main components of the household solar energy is approved and implemented by the relevant departments. It will play a positive role in guiding the selection of the components of the solar hot water system components and improving the service life, reliability and stability of the solar hot water system.

另外，家用太阳能主要部件选材标准》主要推荐的常用的使用幼稚的资料，对于新型资料采取相对谨慎的态度。比方，对于水箱内胆的选材，仅规定行业内已经得到广泛使用的不锈钢和搪瓷，并未涉及近年来出现的工程塑料等新型材料。

In addition, the commonly used naive materials recommended by the standard for selection of main components of household solar energy are relatively cautious for new materials. For example, the material selection of the tank tank only stipulates the stainless steel and enamel, which has been widely used in the industry, and does not involve new materials such as engineering plastics, which have appeared in recent years.
