Foreword
Instead of the standard YS/T 564-2006 "iridium crucibles."
Compared with this standard YS/T 564-2006, the main changes are as follows.
--- Deleted Table 1 "diameter × height";
--- Remove the 4.1 "iridium raw material analysis by GB/T 1422 Appendix A of the method."
This standard by the National Standardization Technical Committee of non-ferrous metals and centralized.
This standard was drafted. Your research Platinum Ltd., China Nonferrous Metals Industry Standards and Metrology Institute for Quality.
The main drafters of this standard. Xu Kun, He Dongjiang to Lei, Zhang Xin, Li Jinghua, Zhang Yong, Tang Min.
This standard replaces the standards previously issued as follows.
--- GB/T 1597-1979;
--- GB/T 1597-2004;
--- YS/T 564-2006.
Iridium crucibles
1 Scope
This standard specifies the technical requirements for iridium crucibles, test methods, inspection rules and signs, packaging, transportation, storage, and purchase order (or contract)
Content.
This standard applies to the growth of laser crystals and special-purpose casting and production of plate welded iridium iridium crucibles.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 1422 iridium powder
GB/T 1423 precious metals and their alloys density test methods
3 Requirements
3.1 Product Classification and Labeling
3.1.1 iridium crucibles according to the manufacturing method of casting into iridium crucibles, iridium plate welded iridium crucibles.
3.1.2 iridium crucibles by casting iridium crucibles, iridium plate welded iridium crucibles labeled C (cast), W (welding) specifications to h (height), (straight
Diameter), d (wall thickness), R (bottom radius) mark.
Example 1. No. 1, a height H, diameter , wall thickness d, a bottom radius R of the casting iridium crucibles, labeled.
C010h × × d × R
3.2 Chemical composition
Iridium iridium crucible purity of raw materials should not be less than GB/T 1422 in SM-Ir99.95 grade requirements.
3.3 the crucible-shaped
Crucible shape Tagging should meet the requirements of Figure 1.
--- diameter; O --- R of the center;
