Foreword

This standard is equivalent to international standards ISO 1922.2001 "rigid foam shear strength" in the technical content and standards Quasi-structure and ISO 1922.2001 is identical, as only a few editorial changes. This standard replaces GB/T 10007-1988 "rigid foam shear strength." This standard 10007-1988 major changes compared to GB/T as follows. --- Increased Chapter 2, "Normative references"; --- An increase of 5.2 "sample request"; --- Increased Chapter 10, "precision and bias"; --- Increasing the test report part (anisotropic material in the application direction of the force, test date); --- Added Appendix A. Appendix A of this standard is a normative appendix. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee of plastic products. This standard is drafted by. Beijing Technology and Business University, Jiangsu Provincial Institute of Chemical Industry Co., Ltd., Jiangsu Province, polyurethane products quality supervision and inspection ST. The main drafters of this standard. Zhou Nan skullcap, Chen Qian, Wu Hao, Wang Xiangdong. This standard replaces the standards previously issued as follows. --- GB/T 10007-1988.

4.1 Testing Machine Testing machine (see Figure 1) requirements are as follows. a) Preparation of the samples are in Chapter 5 of the vertical fixed between two metal support frame, a connecting bracket of metal fixture fixed, another Movable, stress transfer along the longitudinal axis direction of the sample; b) movable grippers able to (1 ± 0.5) mm/min along the longitudinal direction of the moving speed of the specimen; c) the maximum force indication error logger recorded 1%, the maximum distance between two supporting frames indication error of 0.01mm. 4.2 metal support frame Metal stents rectangular carbon steel, machined side. A thickness of (16 ± 1) mm, a width of 50 + 1 0 mm. Kim connection The thickness of the connector bracket and fixture should belong to the same sample thickness. Connections with metal stents chuck shown in Figure 1. 4.3 Adhesives The shear strength and modulus of the sample is bonded to the metal bracket adhesives should be higher than the sample, in order to ensure that the final destruction of the test is to test The adhesive layer of the sample. Suitable adhesives and methods of use in Appendix A. GB/T 10007-2008/ISO 1922.2001 ......
