another international coating standard developed under the leadership of Changzhou Academy was approved to be released, At the beginning of the new year, the international standard ISO developed under the leadership of CNOOC Energy Technology & Services Changzhou Institute adopted a fair structure and function design 23169:2020 "paints and varnishes - field test method for quality assessment of interior wall coatings" was officially approved and issued, becoming the second international standard "paints and varnishes - determination of moisture content - gas chromatography", The second international standard formulated and issued by China in the field of coatings. The test method of this standard is original in China, and its scientificity and applicability are suitable for international promotion
at present, the quality evaluation of interior wall coating system mainly adopts the laboratory method, and the field test method is almost blank, especially the ISO layer coating. In the past, the construction site was mainly evaluated by visual, nail scraping and touch methods. These methods are subjective in 2012 and cannot be quantified. The evaluation results will vary from person to person. ● punch: DP φ 32 poor repeatability, unable to objectively evaluate the quality of on-site interior wall coating. By adopting the methods of coating system cleanability and on-site wet scrubbing specified in this international standard, different grades of coating quality can be distinguished. The method has universal applicability. The evaluation results can also scientifically reflect the advantages and disadvantages of the coating system and coating construction process, and provide a scientific on-site inspection basis for the quality evaluation of interior wall coating
the international standard began to prepare proposals at the beginning of 2017. The international standardization annual meetings in 2017 and 2018 were used to introduce the project to foreign experts. The project was successfully established in January 2018 and officially approved for issuance in January 2020. This is the rule of the market, nearly one year earlier than the expected release date in January 2021. As the domestic technical counterpart of iso/tc35 and iso/tc256 international standardization organizations, Changzhou Institute actively participates in the preparation and revision of international standards. In the future, Changzhou Institute will gradually change to the leading international standard preparation and revision in the core technology field, effectively promote the process of international standardization in China's coating field, and continuously improve the voice and influence of China's coating and pigment industry in the field of international standardization
