Foreword
Appendix A of this standard is a normative appendix.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard by the People's Republic of China Wuxi Entry-Exit Inspection and Quarantine Bureau, Xi'an Polytechnic University, Jiangsu Provincial Fiber Inspection is responsible for drafting.
The main drafters of this standard. Xusheng Jiang, Sun Runjun, Yanxiang Gang, Ma Junling, Shi Qing, Tianlin Hui to Kan, Li Wei, Li Hui.
This standard is the first entry-exit inspection and quarantine develop industry standards.
Textile anti-microwave performance test methods
Waveguide method
Warning. When tested according to the standard anti-microwave properties of textiles, the implementation of this standard should be familiar with the operation, to prevent microwave test
Give way.
1 Scope
This standard specifies the test method for determining the performance of the textile anti-microwave using waveguide method.
This standard applies to all types of textiles and textile products, also applies to film or plate material products of a certain thickness.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard. However, according to research encourages the parties to the agreement

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
A frequency of an electromagnetic wave, an electromagnetic wave through the transmit power accounted textiles through source power percentage.
3.2
A certain frequency of electromagnetic waves, electromagnetic waves reflected through textiles percentage of transmit power source power.
3.3
A frequency of an electromagnetic wave, electromagnetic wave absorption through textiles accounted transmit power source power percentage.
3.4
Electromagnetic radiation on the number of reciprocal transmittance.
Principle 4
The textile sample is placed in a waveguide can transmit electromagnetic waves while testing certain frequency, the power of certain electromagnetic waves (microwaves) after spinning
Through and reflected power, and calculates the corresponding frequency electromagnetic wave transmittance, reflectance, absorbance and shielding effectiveness when fabric. Transmissive
, Reflectance, absorbance and shielding efficiency of the four indicators used to characterize anti-microwave performance textiles.
5 Instruments
5.1 Test equipment should have the simultaneous detection of the sample is calculated reflectance, transmittance, shielding effectiveness, absorption rate index, the basic components of the instrument see
Appendix A.
