Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 19281-2003 "calcium analysis methods," compared with the GB/T 19281-2003, in addition to editorial changes outside The main technical changes are as follows. --- Increasing the aluminum content, the wear rate, the content of cadmium, lead content, nickel content, hexavalent chromium and mercury content determination method (see 3.27 ~ 3.32); --- After the determination of the content of alkali metal and magnesium sulfate was added to the firing temperature was adjusted (see 354, 2003 edition of 3.6.3.); --- The determination of manganese content in heating boiling time has been adjusted (see 3841, 2003, edition of 3.9.4.1...); --- On the determination of loss on ignition temperature has been adjusted (see 3142, 2003 version 3.15.2.); --- The measurement time oil absorption values \u200b\u200bwere adjusted (see 3203, 2003 version 3.21.3.); --- Measure the particle size increases the laser particle size analyzer method (see 3.26 2, 2003 version 3.27). 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) centralized. This standard was drafted.
