Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 14615-2006 "Determination of the rheological properties of the physical properties of wheat flour dough, tensile test method", and The main technical changes compared with GB/T 14615-2006 are as follows. --- Revised scope (see Chapter 1, Chapter 1 of the.2006 edition); --- Revised the normative reference document (see Chapter 2, Chapter 2 of the.2006 edition); --- Added "stretching curve", "energy", "extensibility", "constant deformation tensile resistance", "maximum tensile resistance" and "R/E ratio" Language and definition (see Chapter 3); ---Modified the description of "stretcher" and "powder meter" (see 6.1 and 6.2,.2006 and 6.1 and 6.2); --- Revised the recommended standards in the "sample" (see Chapter 7, Chapter 7 of the.2006 edition); --- Revised the standard in the "Measurement of moisture content of wheat flour" (see 8.1, 8.1 of.2006 edition); --- Modified the process of "preparing the instrument" (see 8.2, 8.2 of the.2006 edition); --- Modified the process of "preparing dough" (see 8.4, 8.4 edition of.2006); --- Modified the "measurement" operation process, the operation of the mechanical tensile tester is listed in Appendix B (see 8.5 and Appendix B,.2006 edition) 8.5); --- Revised the "result representation" (see Chapter 9, Chapter 9 of the.2006 edition); --- Added "precision" (see Chapter 10); ---Modified "Description of Stretcher" (see Appendix A, Appendix A of the.2006 edition); --- Removed "Interlaboratory Test Results" (see Appendix B of the.2006 edition); --- Added detailed interlaboratory precision verification results (see Appendix C). This standard refers to ISO 5530-2.2012 "Physical properties of wheat flour dough - Part 2. Determination of rheological properties. Preparation of the Law. This standard was proposed by the National Grain and Material Reserve Bureau. This standard is under the jurisdiction of the National Grain and Oil Standardization Technical Committee (SAC/TC270).
