Recently, Big Dragon's PVC flooring manufacturer has been granted a new visa. After several months of rigorous on-site auditing, product sampling testing and data review, the PVC composite flooring and homogeneous and transparent PVC flooring of Dajulong Group have successfully passed the evaluation of the American Science Certification System (SCS) and obtained the FloorScore Certification Certificate.

?    FloorScore certification is the world's leading independent certification. The third-party certification, which combines the American Scientific Certification System (SCS) and the Flexible Floor Covering Institute (RFCI), has been strictly tested and certified to make the indoor air quality meet the requirements of health emission standards for surface flooring. Evaluating volatile organic compounds (VOCs) must conform to the strictest measurement and health-based specifications.
 
  The acquisition of FloorScore certificate has very strict requirements. Dajulong Group assures consumers that certified PVC floors meet California Standard 01350V1.2, the LEED building requirements of the American Green Building Association, and meet the indoor air quality emission standards of many environmental health building projects, such as the High Energy Efficiency School Cooperative Alliance (CHPS) and the Green Guidelines for Medical Buildings of the United States.

     In the FloorScore certification requirement, the manufacturer must submit a written quality control plan, including strict requirements for supply chain management. By developing or purchasing raw materials with target low concentration (VOCs), the manufactured products are up to standard and certified. Floor Score can be said to be a more comprehensive certification, and is the world's most stringent indoor air quality standards.
 
The acquisition of the US International Certification Certificate and the "Green Pass" for Big Dragon to the world will greatly promote the internationalization process of Big Dragon Group.
