e. Attribute. A characteristic or property which is appraised in terms of whether
it does or does not exist (for example, go or no-go, pass or fail) with respect to a given
requirement.
f. Defect. Any nonconforming unit of product with specified requirements or
any state or condition of nonconformance to requirements.
g. Defective. A unit of product which contains one or more defects.
h. Defects per Hundred Units. Defects per hundred units (DHU or DPHU)
expresses nonconformance based on the number of defects in the sample. The
number of defects per hundred units of any given quantity of units of product is one
hundred times the number of defects contained therein (one or more defects being
possible in any unit of product) divided by the total number of units of product, that is:
Number of Defect x 100
Number of Units
i. Grand Lots. Grand lots is an administrative procedure where two or more
lots from one contractor/assembler are grouped into one grand lot. Products are not
normally moved for inspection purposes. However, the samples are selected
proportionally from and representative of each contractor's/assembler's lot.
j. Grand Lotting. Collecting or grouping two or more lots presumed equal in
quality in order to decrease the cost of surveillance inspections by reducing the number
of samples.
k. Major A Defect. This classification should be used for defects that are likely
to cause hazardous or unsafe conditions for individuals using, maintaining, or
dependent upon the product. The words 'are likely to' are important. They do not mean
'could possibly' since it is always possible to develop grand scenarios that transform
trivial happenings into major catastrophes. Therefore, the use of this classification
requires experience, prudence, and sound judgment.
l. Major B Defect. This classification should be used for defects that are not
hazardous or unsafe. However, they may restrict the use of the product or make its
consumption unlikely under the conditions for which the rations were designed
originally. Examples of such conditions are extreme color (darkening), extreme odor
(rancidity), or extreme flavor (bitterness) changes in primary components of a ration that
make them unlikely to be consumed under normal field conditions where resupply or
