This document has been modified to adopt ISO 6497.2002 "Animal Feed Sampling".
Compared with ISO 6497.2002, this document has many structural adjustments. Comparison list of structure number changes between the two files
See Appendix A.
The technical differences between this document and ISO 6497.2002 and their reasons are as follows.
---Changed the scope (see Chapter 1, Chapter 1 of ISO 6497.2002), clarified the feed types, and harmonized with domestic feed standards
Adjustment makes it easier for document users to understand and apply;
---Changed the requirements for sampling personnel (see 6.1, Chapter 4 of ISO 6497.2002), in line with the actual situation of my country's feed industry;
--- Added requirements for product identification before sampling and that the packaging should be intact during the inspection process (see 6.3), in line with the actual situation of my country's feed industry
actual situation;
---The classification of solid feed has been deleted [see 8.2a) and 8.2b) of ISO 6497.2002], which is in line with the actual situation of my country's feed industry;
---Changed some product examples in the sampling of powdered products (see 7.2.1, 8.5.1 of ISO 6497.2002), in line with my country's feed laws
Consistent regulations;
--- Changed the requirements for the minimum number of samples for stacking, silage cellars, products in silage piles and product bales (see 7.3.5.3,
7.3.5.4, 8.6.5.3, 8.6.5.4 of ISO 6497.2002), consistent with the context;
--- Added requirements for the minimum number of samples for product sampling during handling (see 7.3.5.5), consistent with the context;
---Changed some requirements for the preparation of laboratory samples (see 7.3.6, 8.6.5.6 of ISO 6497.2002), in line with my country's feed industry
The actual situation of the industry;

Feed sampling
1 Scope
This document describes methods for sampling feed during quality control activities for commercial, technical and legal purposes.
This document applies to compound feeds, concentrated feeds, concentrate supplements, additive premixed feeds, feed additives and feed raw materials.
sampling.
This document does not apply to pet food, nor does it apply to sampling for microbiological testing purposes.
This document stipulates different sampling conditions and requirements for feeds with different physical properties, which contain non-uniformly distributed toxic and harmful substances.
See Appendix B for the sampling of feed containing toxic substances (mycotoxins, castor seed shells or toxic seeds, etc.).
Note. For the sampling of certain types of feeds that have been stipulated in international standards or national standards, see GB/T 5524, GB/T 10360, ISO 707.2008, ISO 7002.

batch lot
batch

Note. The consistency of characteristics mostly comes from products provided by a single manufacturer, and the manufacturer always uses the same production process, production is stable, and individual characteristics comply with
Follows a normal distribution or is approximately a normal distribution (please note that special circumstances may cause distribution details to change). Therefore, the word "batch" in this document
Refers to the "inspection batch", that is, a certain amount of deliverables from which samples are taken and used for inspection, which may be different from the concept of "batch" in the transportation link.
3.3
Sample increment
A sample taken from a certain point in the same batch of products.
3.4
total sample bulksample
A sample obtained by combining and mixing all samples taken from the same batch of products.
Note. A collection of samples that are collected for separate investigation and have obviously (identifiable) different sub-samples is expressed as "total sample".
3.5
