Author/Source: Henan Jinkai; Date: November 24, 2021; Page views: 25. Recently, the results of the CABR-2021-PT61 proficiency testing program, which lasted for 8 months, were released. The test results submitted by the Quality Management Department’s laboratory of the group regarding urea content, density, biuret, and aldehydes were all satisfactory. This proficiency testing program is an effective external quality assurance activity; it complements internal quality control techniques and serves as recognition of the Group Company’s capability in “chemical analysis of urea aqueous solution for automotive use”. To enhance the market competitiveness of its urea products for use in vehicles, the group company has currently introduced urea aqueous solutions of types 32, 55, and 70. The laboratory of the company’s quality management department, following the chemical analysis methods for determining the total nitrogen content in urea, organized technical staff to simplify the testing conditions and optimize the testing procedures. As a result, the corporate standard Q/HJK 017-2021 \"Urea Concentrate for Use in Vehicles\" was developed and implemented, providing technical support for the quality control of the company’s urea aqueous solutions. It is reported that, in accordance with the \"Measures for the Implementation of Laboratory Proficiency Testing\" issued by the **Commission for Certification and Accreditation Supervision and Management (Announcement No. 9 of 2006)** and the \"Proficiency Testing Rules\" of the China National Accreditation Service for Conformity Assessment (CNAS-RL02:2018), organizations that achieve satisfactory results in proficiency testing programs can use these results as an important technical basis for applying for or maintaining CMA accreditation as well as CNAS competence recognition. They can also serve as a valuable technical reference for streamlining the process of verifying the competence of relevant testing methods. http://img.yf116.cn/image/img/20211124/949533539357.jpg
