In some fast-developing industries related to precision technology, biotechnology, food, hygiene, etc., clothing is required to block air dust and pollution. At the same time, the wearer usually hopes that the clothing will not stick to the skin or produce uncomfortable electric shocks. Many national and international standards, including ISO and IEC, have standards for electrostatic performance evaluation, which are used to guide clothing design. To avoid problems caused by static electricity. However, the relationship between the measured electrostatic performance and the end-use performance is more complicated and may require Use different methods for testing according to the actual situation of the application. This document is one of the testing methods for the electrostatic properties of textiles. This document does not give clear performance requirements, only in the informative Appendix A The reference for the evaluation of the results is given in the performance evaluation table. The performance evaluation table is based on the prevention of adhesion, electrostatic discharge discomfort and particulate pollutants in the industry. Adsorption and other related experiences are set for reference only. It is recommended that users of this document check their applicability according to their own application conditions. Textile electrostatic performance test method Part 1.Corona charging method1 ScopeThis document describes a test method for measuring the attenuation and decay time of the peak voltage of the fabric using the corona charging method. This document applies to textile fabrics. This document does not apply to the evaluation of clothing and clothing materials related to personal safety and protection of electrostatic discharge sensitive devices.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text.
