Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 16553-2010 "jewelery identification." This standard compared with GB/T 16553-2010, the main changes are as follows. --- Modify the scope of the standard (see Chapter 1). --- Added a reference to terms and definitions in GB/T 16552, deleted "special optical effects" "heat treatment" "proliferation treatment" and so on Duplicate terms and definitions; Removed terms and definitions of "Color" "Immersion Oil" "Baptist wax"; Modified "Fluorescent" "Phosphorescent" technique Language and definition; Added terms and definitions of "inclusions". (See Chapter 3) --- The conventional identification method and special identification method for the identification method; the identification method of "UV fluorescence" to "fluorescence concept Observation "; the" absorption spectrum "in the identification method is incorporated into" UV-Visible spectroscopy "(see 4.1) --- Modify the infrared spectroscopy, laser Raman spectroscopy and other methods of identification methods and the scope of application; the infrared spectroscopy Analysis, UV-visible spectrum analysis, laser Raman spectroscopy and other identification methods in the operating steps, instead of jade jewelry identification Application; Added luminescence spectroscopy. (See 4.1) --- Identification project will be "UV fluorescence" to "fluorescence observation", delete the absorption spectrum, increase the infrared spectrum, UV-visible spectrum, Raman Spectrum and other projects; modified the selection principle of identification items. (See 4.2) --- Increased the identification of the various jade jade varieties infrared spectroscopy. (See Chapter 5) --- Increase blue Fang Shi, sphalerite, Balin Shi, Chang fossil, conch beads, mammoths and other species and subspecies identification characteristics; Turquoise identification characteristics. (See Chapter 5) --- Increase and modify the diamond, emerald, spinel, turquoise, Su-stone, amber and other major types of jewelry jade optimization processing Type and identification features; standardize the various jade jade species material properties and dyeing, filling, laminating and other processing methods identified characteristics of the description Description. (See Chapter 5) --- Reference GB/T 16552 jewelry jade name standards for the revised content of the corresponding additions and deletions revision. This standard proposed by the Ministry of Land and Resources. This standard by the National Gems Standardization Technical Committee (SAC/TC298) centralized. This standard was drafted unit. National jewelery quality supervision and inspection center.
