The standard T/YNIA 013-2023 for Geosynthetic Nonwovens was published on February 2, 2023, and came into effect on March 2, 2023. This standard is aimed at providing guidelines and technical specifications for the production, testing, and application of nonwoven fabrics used in geotechnical engineering projects in China. It covers a wide range of requirements including raw material selection, product performance indicators, quality control measures, and environmental protection considerations to ensure that nonwovens meet the necessary standards for various geosynthetic applications.
The development of this standard was led by the Yunnan Nonferrous Metals Industry Association (YNIA) in collaboration with experts from research institutions, universities, and industry practitioners. It aims to promote the advancement and international competitiveness of China's nonwoven fabric industry through innovation and compliance with rigorous quality standards.
This document outlines specific test methods for assessing properties such as tensile strength, tear resistance, hydraulic conductivity, and filtration efficiency. Additionally, it provides guidance on proper installation techniques and maintenance practices to maximize the longevity and effectiveness of geosynthetic nonwovens in their intended applications.
