This standard applies only to products are fairly similar.
this standard Used in the following situations: sure
A) --, feel the difference (2-3 inspection test difference);
- no feeling difference (2-3 inspection test similar), for example when ingredients, process, packaging, processing or storage when there is a change.
B) used for selection, training and testing evaluation member
this standard method of two forms:
- a constant reference technology, used for evaluation Familiar with a product (e.g., samples from fixed line);
