Foreword
Chapters 1, 4 and 6 of this standard are mandatory; the rest are
recommended.
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 22549-2008 “Feed additive - Dicalcium
phosphate”.
As compared with GB/T 22549-2008, the main technical changes except
editorial modification are as follows.
- MODIFY arsenic index parameters from 0.003% to 20 mg/kg (SEE 4.2; 5.2
of 2008 version);
- DELETE dithizone spectrophotometric method in the determination of lead
content (6.11.2 of 2008 version);
- ADD the chromium content index parameters and test methods (SEE 4.2,
5.13);
- ADD free water index parameters and test methods (SEE 4.2, 5.15).
This standard was proposed and shall be under the jurisdiction of the National
Feed Industry Standardization Technical Committee (SAC/TC 76).
