   The type of the product can be clearly distinguished from the picture above. One of the drafters of the standard, Director Luo Huaiping of Guangzhou Weikai Testing Technology Research Institute, said in an interview that such products currently used in people's daily life are basically universal. jack products.
 Luo Huaiping said that although products that did not meet the new national standards are theoretically defined as substandard products since June last year, most companies are still continuing to produce them. According to the plan, the large-scale universal products can be used up in about half a year, but because the company has not stopped production, the large-scale universal products still account for the majority in the market.
     Wen Xiaojuan, product manager of Huntkey power converters, said that the fundamental reason why most products on the market have not been improved in accordance with relevant requirements is that most small companies are worried about the implementation of the new national standards, so companies are watching each other. The implementation depends on the quality supervision of the products by the state agencies and the leading role of the industry leaders."

       Wen Xiaojuan revealed that if the quality inspection department cannot increase the inspection and punishment, many companies will continue to produce products that do not meet the new standards, because although the regular supermarket channels are difficult to enter, the supervision of county-level supermarkets and hardware wholesale markets is not strong. Therefore, the products of the old standard will probably continue to be sold in this channel, and the authority of the national mandatory standard will be challenged.
      A relevant person from China Wujinjiaodian Chemical Business Association said that the previous products had potential safety hazards such as fire. The new national standard power converter plug and socket have a larger contact area and closer contact, which can effectively prevent heat generation and have better anti-electric shock performance. This will greatly improve the safety performance of socket products. In addition, the person in charge of the relevant enterprises said that the price of the product will not be raised by this.
