Situation analysis of evaluation standard for measuring shielding effectiveness of anti-electromagnetic radiation textiles

Effective testing and evaluation for anti-electromagnetic radiation textiles is the key of products, development and application. This paper introduced the electromagnetic shielding principle of anti-electromagnetic radiation textiles and the development status of evaluation methods for measuring shielding effectiveness. It analyzed the test method of anti-electromagnetic radiation textiles standards. The problems of current standards and test methods of civil electromagnetic shielding textiles were discussed. The author pointed that professionals should improve the standards of electromagnetic shielding textiles. Besides, professionals should make clear the requirement of shielding effectiveness for civil anti-electromagnetic radiation clothing. In addition, comprehensive evaluation method of anti-electromagnetic radiation performance should be established based on the features of clothing structure. These will provide reasonable testing and evaluation basis for anti-electromagnetic radiation textiles,production guidance and market supervision.
