T/BIAS 3-2019 Active

Main technical content: Practical experience of assembly-type concrete construction projects shows that for a wide variety of precast concrete component products with inconsistent numbering rules, adopting a scientific product identification method is necessary and effective for the technical management and product research and development of various enterprises; at the same time, it actively guides and promotes the coordinated development of standardized technology for precast concrete components. During the preparation of this standard, we summarized the practical experience of precast concrete component product identification in recent years, fully adopted the identification systems that have been applied in engineering practice, and, on the basis of extensively soliciting opinions from relevant units such as design, production, and installation and construction, conducted repeated discussions and modifications, and finally reviewed and finalized the standard. The main contents of this standard include: 1. General provisions; 2. Terminology; 3. Basic provisions.
