3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 Item
Item is a basic unit divided for the demand of carrying out sampling inspection.
[GB/T 2829-2002, Definition 3.1.1]
Example: a single product, a pair of products, a group of products, a component, or a part of a
certain length, a certain area, a certain volume and a certain weight.
3.2 Lot
Requirement refers to a demand or expectation that is explicitly expressed, usually implied, or
must be fulfilled.
[GB/T 19000-2008, Definition 3.1.2]
NOTE 1: “usually implied” refers to the routine or general practice of an organization, customer
and other interested parties where the demands or expectations under consideration are
self-evident.
NOTE 2: specific requirements may be expressed with modifying words, such as: product
requirements, quality management requirements and customer requirements.
NOTE 3: specified requirements are explicitly expressed requirements.
NOTE 4: requirements may be proposed by different interested parties.
3.9 Quality Characteristic
Quality characteristic refers to an inherent characteristic of a product, process or system related
to a requirement.
[GB/T 19000-2008, Definition 3.5.2]
NOTE 1: “inherent” refers to something inherent in some object, especially a permanent character.
NOTE 2: the characteristics (such as: the price of a product and the owner of a product) endowed
to a product, process or system are not its quality characteristics.
3.10 Conformity
Conformity refers to the satisfaction of a requirement.
[GB/T 19000-2008, Definition 3.6.1]
3.11 Nonconformity
Nonconformity refers to the failure to satisfy a requirement.
[GB/T 19000-2008, Definition 3.6.2]
NOTE: nonconformity is classified in accordance with the importance of quality indicated by
quality characteristic, or the severity of nonconformity of quality characteristic. Generally,
nonconformity is divided into nonconformity type A, nonconformity type B and
nonconformity type C.
3.12 Nonconformity Type A
Nonconformity type A means that an extremely important quality characteristic of an item fails
to satisfy a requirement, or the quality characteristic of an item extremely severely fails to
satisfy a requirement.
NOTE: GB/T 2829-2002, Definition 3.1.8 is modified.
3.13 Nonconformity Type B
Nonconformity type B means that an important quality characteristic of an item fails to satisfy
a requirement, or the quality characteristic of an item severely fails to satisfy a requirement.
NOTE: GB/T 2829-2002, Definition 3.1.9 is modified.
3.14 Nonconformity Type C
Nonconformity type C means that a general quality characteristic of an item fails to satisfy a
requirement, or the quality characteristic of an item slightly fails to satisfy a requirement.
NOTE: GB/T 2829-2002, Definition 3.1.10 is modified.
3.15 Nonconforming Item
Nonconforming item refers to an item with one or more nonconformities.
NOTE 1: in accordance with the severity of nonconformity, nonconforming item is usually divided
into nonconforming item type A, nonconforming item type B and nonconforming item
type C.
NOTE 2: GB/T 2828.1-2003, Definition 3.1.7 is modified.
3.16 Nonconforming Item Type A
Nonconforming item type A refers to an item with one or more nonconformities type A, and

[GB/T 2829-2002, Definition 3.1.12]
3.17 Nonconforming Item Type B
Nonconforming item type B refers to an item with one or more nonconformities type B, and

[GB/T 2829-2002, Definition 3.1.13]
3.18 Nonconforming Item Type C
Nonconforming item type C refers to an item with one or more nonconformities type C, but no
nonconformity type A or nonconformity type B.
