Basic Information
Scope
Scope: This standard specifies the terms and definitions, product classification, evaluation requirements, and evaluation methods for polyurethane shoe materials. This standard applies to the evaluation of high-quality green development and excellent products of polyurethane shoe materials. Main technical content: The content of this standard combines theoretical research and practical experience, featuring both rationality and practicality. The main content includes: (1) Scope: Clarifies the scope of application of the standard. (2) Normative reference documents: Details the normative documents involved in the use of this standard. (3) Terms and definitions: Standardizes the terms and definitions of polyurethane shoe materials. (4) Product classification: Classifies polyurethane shoe materials according to their target users, shoe material structures, material properties, and molding processes. (5) Evaluation requirements: Divides the evaluation requirements for products into basic requirements and key indicators. Basic requirements mainly refer to the compliance evaluation requirements for production enterprises and products. Key indicator requirements consist of first-level indicators and second-level indicators. First-level indicators include safety attributes, quality attributes, and green attributes, while second-level indicators are specific evaluation items for three categories of attributes, including indicator names, benchmark values, and determination criteria. (6) Evaluation methods: Specifies the conditions that polyurethane shoe materials must meet to be considered high-quality green development and excellent products.
