Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard is a revision of GB/T 10288-2003 "Test method for down and
feather".
Compared with GB/T 10288-2003, the main changes of this standard are as
follows.
- MODIFY the "Terms and definitions";
- Standard atmospheric environmental conditions are implemented in
accordance with the GB/T 6529-2008 standard; MODIFY the tolerance
range of relative humidity from ±2.0% to ±4.0%;
- ADJUST the "sampling quantity" and the number of specimens, which are
required for some inspection items;
- In the component analysis, ADD the inspection of "quill feather";
- In the type identification of goose and duck down, ADD a secondary
classification rule for the down and feather that cannot be distinguished;
- CHANGE the pre-treatment method for filling power test into "steam
reduction method". The filling power test adopts the filling power tester,
which is specified by the test rules of International Down and Feather
Bureau (IDFB). ADD an inverting barrel, as the down filling device;
- ADJUST the inspection of "turbidity", which is divided into method A (visual
inspection method) and method B (special turbidity detector method);
- In the inspection of "fat and oil content", MODIFY the requirement for the
number of refluxes; CANCEL the use of the rotary evaporator;
- ADD the requirements for inspectors in the "odor" inspection; MODIFY the
result judgment;
- ADD the inspection of "acidity (pH value)";
- In the inspection of "moisture content", ADD the calculation formula of
"moisture regain"; CLARIFY the requirements for packaging containers;
- Except for "turbidity", all test results are kept to one decimal place;
- ADD the content of the test report;
- DELETE the contents of Appendix A (microbiological testing methods);
This standard was proposed by the China National Light Industry Council.
This standard shall be under the jurisdiction of the National Leather Industry
Standardization Technical Committee (SAC/TC 252).
