T/CPCIF 0291-2023 Green Design Product Evaluation Technical Specification for Polytetrafluoroethylene

Scope

Scope: This document specifies the evaluation principles and methods, evaluation requirements, and preparation methods for life cycle assessment reports of green design products made from polytetrafluoroethylene (PTFE). This document applies to the evaluation of green design products made from PTFE produced by the suspension or dispersion method; Main technical content: 4. Evaluation principles and methods 4.1 Evaluation principles 4.1.1 The principle of combining life cycle assessment with indicator evaluation According to the life cycle assessment method, considering the entire life cycle of PTFE, in-depth analysis of resource consumption, ecological environment, and human health factors at various stages, and selecting evaluable indicators at different stages to form an evaluation indicator system. 4.1.2 The principle of optimally selecting environmental impact types According to the characteristics of PTFE, select environmental impact types with significant impact, high social attention, and clear requirements in national laws or policies, such as human toxicity impact and product attributes. 4.2 Evaluation methods and processes 4.2.1 Evaluation methods PTFE that meets the following conditions can be called a green design product: a) Meet the basic requirements (see 5.1) and evaluation indicator requirements (see 5.2); b) Provide a life cycle assessment report for the PTFE product. 4.2.2 Evaluation process According to the characteristics of PTFE, clarify the evaluation scope, collect relevant data based on the indicators of the evaluation indicator system and the life cycle assessment method, analyze the data, and evaluate the PTFE against the basic requirements and evaluation indicator requirements. If the PTFE meets the basic requirements and evaluation indicator requirements, it can be determined that the PTFE meets the evaluation requirements for green design products; The PTFE production enterprises that meet the requireme
