EN 14411对应的国家标准（英文）
Introduction
EN 14411 is an internationally recognized classification system for ceramic tiles. It categorizes tiles based on various physical and technical properties. In this article, we will explore the corresponding national standard for EN 14411 in China.
1. Background
China, as one of the leading producers of ceramic tiles, has established its own national standard to ensure the quality and consistency of products. This standard, known as GB/T 4100, provides specifications and testing methods that align with the requirements of EN 14411.
2. Scope
GB/T 4100 covers ceramic tiles for both wall and floor applications. It includes tiles made from various materials such as porcelain, stoneware, and earthenware. The standard defines the technical characteristics, dimensions, and tolerances of these tiles.
3. Classification
Similar to EN 14411, GB/T 4100 classifies ceramic tiles into different groups based on their water absorption capacity and physical features. The classification helps users to select the appropriate tiles for specific applications, taking into account factors such as durability and resistance to wear.
4. Physical Properties
GB/T 4100 specifies the physical properties of ceramic tiles, including dimensions, surface flatness, and water absorption rate. It defines the requirements for the tolerances of tile size, ensuring consistency during manufacturing and installation.

5. Performance Testing
The national standard also provides guidelines for testing the performance of ceramic tiles. It covers various aspects such as flexural strength, abrasion resistance, and resistance to chemical attack. These tests help determine the durability and suitability of tiles for specific environments.
6. Marking and Packaging
GB/T 4100 requires ceramic tiles to be marked with essential information such as the manufacturer's name, product designation, and the standard number. This ensures traceability and facilitates quality control. Packaging requirements are also specified, ensuring the safe transportation and storage of tiles.
7. Compliance and Certification
To ensure compliance with GB/T 4100, ceramic tile manufacturers in China are required to conduct regular testing and inspection. Third-party certification bodies also play a crucial role in verifying product quality and compliance with the standard. Certification marks, such as the China Compulsory Certification (CCC) mark, provide assurance to consumers.
8. Harmonization with International Standards
While GB/T 4100 is specific to China, efforts have been made to align it with international standards such as EN 14411. This harmonization facilitates trade and exchange of ceramic tiles between China and other countries, as products can be compared based on standardized criteria.
9. Conclusion
The corresponding national standard for EN 14411 in China is GB/T 4100. It provides comprehensive guidelines for the classification, physical properties, performance testing, and marking of ceramic tiles. Adherence to this standard ensures the quality and consistency of ceramic tiles manufactured and sold in China. By aligning with international standards, China aims to enhance its competitiveness in the global market and promote harmonized trade in ceramic tiles.
