On April 26, 2013, the industry standard “Wall-flow Honeycomb Ceramics for Diesel Particulate Filters” drafted by the Shanghai Institute of Silicon Science of Chinese Academy of Sciences, Jiangsu Yixing Non-Metal Chemical Machinery Co., Ltd. and etc., was held in the conference room of our company. During the meeting, relevant experts from the National Industrial Ceramics Standardization Technical Committee attended the seminar. After discussing and communications, experts proposed to amend the revision, and agreed that these standards should be revised and improved as soon as possible.
