All technical contents of this standard are mandatory. Foreword
This standard is a revision of the provision for gold coatings in Q13. Compared with QB113I·1991, the main changes of this standard are as follows: QB11312005 adopts 1S010713:1992 (B) Decorative gold alloy coating (English version): For the convenience of comparison, the comparison table of the characteristics of this standard and the international standard is listed in Appendix 4: The second normative reference document and the internal rate of the inspection method are added; for the purpose of more detailed use, this standard also makes the following editorial changes: a) "International standard" is changed to "Technical standard"; b) "" is used instead of "" as the decimal point; e) The foreword of the international standard is excluded.
Appendix A and Appendix B of this standard are informative appendices. This international standard is issued by China Light Industry Federation.
This standard is issued by the National Standardization Technology Committee (SACTC256) II, and the originating unit of this standard is the National Jewelry Quality Supervision and Inspection Center. The main drafters of this standard are: Fan Jifang, Li Sanou, Li Xingken, and Li Wu. This standard was first issued in June 1991, and this is the first revision. Since the implementation of this standard, the light industry standard QB1131-11 issued by the Ministry of Light Industry has specified the thickness of the gold coating layer of jewelry. This standard specifies the terms and definitions, requirements, inspection methods and requirements for the gold coating of jewelry products! This standard is applicable to non-metal products. 2 Normative references E1131-2005 t||The following clauses in the documents become clauses of this standard after they have been used. From the date of reference: the referenced documents shall be noted. Any subsequent sample list (excluding the content of errors) or revisions shall not be applicable to the following standard. However, the original clauses of the documents shall be used as the basis for the research and development of this standard. For any document without a date, the latest version shall apply to this standard. (QB/T117722 Method for measuring the thickness of gold coating by microscopy QB/T1133 Method for determining the thickness of gold coating on jewelry by chemical method QB/T1135 Method for determining the thickness of gold and silver coating on jewelry by X-ray diffraction method 3 Terms and definitions
The following terms and definitions apply to this standard. If the standard is screened according to the table 1, the first The requirements for the alloy content of the decoration can be determined according to the values ​​specified in the table.
Note: The requirements for the two layers are also related to the selection of the gold content of the product. This method of determining the gold content is again expressed in "m eme (thousandth value") in the setting number. In this case, for the actual measurement of the covering layer, the sample station is not the maximum amount, the maximum surface and the rate of cross-sampling. This value is expressed in points. However, to change the meaning of this material with the international standard, the maximum value must be expressed in the table. 3.1
Gold-plated oxygen capping layer rolled gold
The gold layer obtained by mechanical folding method on the decoration body is called gold-plated summer layer. 3.2
Gold-plated thin capping layer gilded The gold covering layer obtained by chemical plating or chemical plating is called gold-plated covering. QH 1131-2005 specifies the following: new engineering methods: six-technique heat method, common method, classification, processing and requirements, purity (minimum: 58556a). The gold covering layer is composed of gold, which is pure gold. The following points will be used to measure the purity of the gold coating: tt||5754 gold-23.m
8 life 1.2uT
667 will be 4 life m
more than the accurate limit of the gold distribution, so: the United States letter, the government of my pure film: the method of reporting this proposal 4 requirements
4.1 purity of the gold coating
1 gold recommended layer should contain the concept of 35% lower, the gold content in the compensation should not be less than 85%. 4.2 Thickness of gold cover layer
4.2.1 Gold cover screen
Wet cover thickness is not less than 0.5m.
4.27 Gold-plated cover thickness is not less than -t0.sun1.
4.2.3 Full layer thickness gold layer
Gold thickness u.5m
5 Inspection method
5.1 Basic method Destruction method:
But or grid center adopt chemical analysis method. According to the quality, the average thickness of the gold residue should be calculated before the machine table. For detailed description of chemical analysis method, please refer to QBT53, 5.2 Second method Non-destructive inspection training method)
Q1131-2005
Exchange, production, business! The buyer can use the carbon fiber optical method, the frequency scanning method, the electron microscope method, the signature method, the 11135 or GB/T17722.
If the method can be proved to be accurate, it can also be used. 6 Marking
6.1 The product auction table 1 requires and selects the following double-chuan certification 6.1.1 I am the name of the LA
Example: 1-HAu. Applicable gold limit five layers: this layer of tiger m, the minimum is?% 6.1.2 Adjustment gold fee original specification: PA
: -AA, suitable code + lock gold method: US will S: small customer gold S6.? If there is any other certification, the internal price of the producer will be more than the mark of the product 6.3 Debt house: gold products are not allowed to be marked or! 6.4 Production time. The upper part does not need to be marked with a gold chain. It is a provincial mark QB1131-2005
