Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 397-2007 "zirconium sponge." Compared to major changes "zirconium sponge" This standard YS/T 397-2007 as follows. --- The atomic level to the nuclear level, increasing the level of firearms; --- Adjust grades, specifically "nuclear grade. HZr-01, HZr-02; Industrial. HZr-1, HZr-2; Firearms Grade. HQZr-1"; --- Adjustment impurity elements in Table 1 and the effective numerical digits and increase Na, P, U three elements content requirements; --- By 26 Alphabetical Rearrange Tables 1 and Table 2 in the order of impurity elements; --- Modify Batch definitions, namely, "by the same production batch cycle, consisting of the same brands of products"; --- Perfect Cl, Mg, Na element sampling sample preparation methods; --- The "net weight does not exceed 20kg" deleted, the new version no longer a requirement.
