Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Rubber and Rubber Products Standardization Technical Committee (SAC/TC35). This standard was drafted. Zhongce Rubber Group Co., Ltd., Qingdao University of Science and Technology, Qingdao Keda New Rubber Technology Service Co., Ltd., Zhejiang Yufu High-tech Fiber Co., Ltd., Qingdao New Material Technology Industrial Park Development Co., Ltd., Qingdao Yuke Materials Co., Ltd., Qingdao Ruirui Da Magnetic Materials Co., Ltd. The main drafters of this standard. He Huiying, Liu Xiao, Liu Li, Song Minggen, Kangle, Zhang Baogang, Feng Xiaomeng. Dipping cord creep performance test method

1 Scope

This standard specifies the test method for the creep properties of dipped cords under set conditions. This standard applies to the test of creep properties of dipped cords made of chemical fibers, and can also be used for dipping yarns and dipping of chemical fiber. Test of creep properties of dipped skeleton materials such as rubber cords.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document.

3 Terms and definitions

The following terms and definitions as defined in GB/T 32110 apply to this document. 3.1 Creep creep The process in which the length of the sample increases with time under a constant load. 3.2 Creep load creepload The load applied by the creep test. 3.3 Creep time creeptime The duration of time the specimen is subjected to creep loading. 3.4 Creep elongation creepextension The difference in length of the sample before and after creep.

4 Test principle

The creep of the dipped cord means that the length of the dipped cord sample increases with time under the action of a certain temperature and constant tensile stress. The process of increasing. During the test, one end of the cord sample is fixed, and the other end is pre-tensioned to measure the length of the sample; then the sample is applied After a certain load and placed in a set temperature environment for a certain period of time, the length of the sample is measured again. Creep front and rear cord samples The ratio of the difference in length to the length of the pre-creep cord sample is the creep rate of the dipped cord sample. ......
