Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard is GB/T 19590-2004 "ultra-fine calcium carbonate," the amendment.
The main difference compared with the standard GB/T 19590-2004 as follows.
--- Describes the product type crystal morphology (Chapter 4 of this edition).
--- Request prominent nanometer core indicators, lists of recommended indicators for special purposes (Chapter 5 edition) in the corresponding appendix.
--- Further improve the test method (s edition Chapter 6).
This standard replaces GB/T 19590-2004 "ultra-fine calcium carbonate."
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee chemical inorganic chemicals Club (SAC/TC63/SC1) and the National Standardization Technical nanotechnology
