Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee dipped rubber reinforcing materials and rubber Technical Committee (SAC/TC35 / SC13) centralized. This standard is mainly drafted by. Yantai Taihe new material Co., Ltd., Dah Sing Qingdao Branch Rubber Technology Service Co., Ltd. Qingdao Branch University of Technology, Co., Ltd. Qingdao day state line. The main drafters of this standard. Ma Qianli, Bing Xin, Liu Li, Jiang Hua, Shao Zhengli. Dipped aramid yarns, cords and cords of tensile properties experiment method

1 Scope

This standard specifies the use of rubber products dipped aramid yarn, rope and cord breaking strength, breaking elongation, constant elongation load, constant load Standard Test Method for Performance of elongation, breaking strength coefficient of variation coefficient of variation of elongation at break, tensile modulus of elasticity. This standard applies to dipped aramid yarn, cord and the cord stretched detection performance.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 6529 Textiles Standard conditioning and testing atmosphere GB/T 8170 repair value expressed about the rules and limit values \u200b\u200band judgment

3 Test principle

Under specified test conditions, the balance after dipping aramid yarn, rope and cord samples, held in a fixed constant elongation (CRE) The type tensile testing machine at a constant rate tensile force pulling the sample until the sample breaks. Read directly from the tensile testing machine or calculated Obtain samples for tensile strength, elongation at a given load, constant load elongation, elongation, breaking strength coefficient of variation, variation in elongation at break Coefficient, elastic modulus tensile properties data.

4 equipment and instruments

4.1 tensile testing machine Use constant elongation (CRE) type tensile testing machine, the test machine should be configured with a self-recording logger or can automatically calculate and display the Badge Quasi-data needed, and should meet the following requirements. a) to record breaking strength and elongation values \u200b\u200band draw strength - elongation curve; Test error b) strength values \u200b\u200b≤1%; c) test error elongation value ≤0.1mm; d) error holding gauge length value ≤1mm; e) holding the specimen holder should be stable, and to ensure that during the test, the sample lower clamp clip inside slip does not occur, and the clip Holding force will not produce damage to the specimen; f) tensile testing machine should be equipped with extensometer. 4.2 tensile testing machine fixture 4.2.1 This standard specifies test should be used in arc jig, the sample was wound between the clip plane, then to partially (corners) around Wire wrapped around the clip groove on the other end of the sample in the same manner on the other winding fixture; jig clamped sample should not slip or the sample Fracture damage. 4.2.2 holder holding mode using pneumatic or hydraulic way. ......
