Foreword

GB/T 14457 is divided into two parts. --- GB/T 14457.2 Determination of boiling range of spices; --- GB/T 14457.3 spices melting point assay. This section GB/T Part of 214,457. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 14457.2-1993 "Isolate and synthetic fragrances Boiling Range assay." And GB/T 14457.2-1993 phase Ratio, the main changes are as follows. --- Standard name from "Isolate and synthetic fragrances Boiling Range Determination" to "spice boiling range determination"; --- By the standard pressure units "hPa" read "kPa" (see 21, 1993 edition Chapter 2; see 5.2.1 and Table 1, Table 2, 1993 Version 5.2.1 and Table 1, Table 2; see Appendix A, 1993 edition Appendix A); --- Increasing the content of the test report (see Chapter 6). This part is proposed by the China National Light Industry Council. This part of the National Fragrance Flavor and Cosmetic Standardization Technical Committee (SAC/TC257) centralized. This section is drafted. Shanghai Spice Institute, Tianjin Product Quality Supervision and Testing Technology Research Institute. The main drafters of this section. Cao Yi, Wang Ping, Xu Yi, Zhao Fusheng. This section was first released in June 1993, this is the first revision. Determination of boiling range of spices
