Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
 an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the
members of the parent committee casting a vote;
 an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS
is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into
an International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 21849 was prepared by Air Transport Association of America, Inc. (as Chapter 9 of ATA SPEC2000,
Revision 2001.1) and was adopted (without modification except those stated in Clause 2 of this document)
by Technical Committee ISO/TC 20, Aircraft and space vehicles.

ISO/TS 21849:2003(E)
Chapter 9. Bar Coding
9-1. Introduction

Accuracy of information exchanged within the airline industry can be improved by using methods other than manual

keying. An alternative is machine-readable code as exemplified by bar code.

Bar code technology provides an accurate, easy, and inexpensive method of data storage and data entry for

computerized information management systems.

Establishment of a common set of specifications provides the base on which to build specific requirements for the

exchange of supply information.

1. Policy

The airline industry designates specific bar code symbologies which are detailed in the respective sections of this

chapter. Use of bar codes should be a cooperative effort by trading partners within the industry to achieve improved

data accuracy and productivity while reducing cost.

2. Purpose

To define the applications for bar code technology within the material management activities in the airline industry.


3. Guidelines

The bar code symbologies used in this specification should be in accordance with Automatic Identification
Man ufacturers (AIM) Uniform Symbology specifications. The print quality should be in accordance with the American
National Standards Institute (ANSI) Bar Code Print Quality - Guideline [ANSI X3.182-1990 (R1995)] with a minimum

Grade C print quality. An ANSI print quality grade of 'C' is the minimum acceptable standard.

When using the Data Matrix symbology, both the square and rectangular formats are acceptable. The Data Matrix Error
Correction Code200 (ECC200) specified by AIM is the only acceptable version. Direct Part Mark (DPM) quality

ratings are still in development at this time.

Only valid character, defined as part of the bar code character set and the ATA Common Support Data Dictionary

(CSDD) should be used.

4. Data Text

All bar codes shall have the data printed in text above, below, or adjacent to the printed bar code symbols.

The interpretation of the pertinent encoded bar code data shall be presented in a human-readable font. The data text of
the bar code shall represent the encoded data. The data text is intended to be used only for human recognition and is not

intended to be machine readable.

9-4 Permanent Bar Code Parts Identification

1. Command Code

Not Applicable




1.1. Purpose

In order that automated processes may be used in parts handling, and to facilitate "cradle-to-grave" tracking of serialized

parts, an industry task force has defined a Permanent Bar Code specification that uses Code 39, Code 128 or Data
Matrix symbology. Code 128 is the preferred linear symbology for Permanent Parts Identification.


Traditionally, aircraft parts manufacturers have used Part Number and Serial Number in combination to uniquely
identify a part. However, where a modification affecting form, fit, or function is applied to the part, the airworthiness

authorities require a new part number to be assigned. This process breaks the Part/Serial Number relationship used to
track the part, thereby presenting problems for the owners, users, and repairers of the part. This specification defines the

data format for a universal serial number that provides a ‘social security number’ concept to uniquely identify the part
throughout its life.

This specification defines standard data and formats for the identification of both new and in-service parts:

A Part Serial Number (SER) or Unique Component Identification Number (UCN), along with a code identifying the

party assigning it, will uniquely identify the part throughout its life, whether or not the Part Number changes. The
combination of the CAGE Code plus the unique SER/UCN number creates a ‘social security number’ for the part. Parts

already in service may be labeled using the owner/user's CAGE Code instead of the manufacturer's. However, this does
not preclude a manufacturer's code being used where the permanent bar code identity is retroactively applied by the

manufacturer, the manufacturer's agent, or the owner when in receipt of the manufacturer's authority. When the original
Serial Number for an in-service part is not unique to the manufacturer, the manufacturer should assign a separate UCN.

To maximize consistency, the MFR, or SPL should always be the first data element in the bar code.

From a data perspective, the MFR and SPL represent the same type of data, specifically, a company’s five character

CAGE Code (outside North America it is called the NATO Manufacturers Supplier Code). From a labeling perspective,
the MFR or SPL are used to represent whether the manufacturer or someone else had the responsibility for marking the

parts and insuring that the Serial Number (or UCN) is unique. Similarly, the SER and UCN are also the same type of
data. Typically, the MFR would have the numbering authority to insure that the SER is unique within their CAGE Code

when the part is new. Any other company marking an In-Service part with the SPEC2000 data format would use the

SPL/UCN combination.

The bar coded information will consist of a Text Element Identifier (TEI) and the corresponding data. The text of the
data will be printed adjacent to the bar code to allow part identification without bar code reader equipment. As a goal,

all parts should be identified by bar code unless technically impractical. For some parts (e.g., jet engine parts) the
technology may not yet exist to label/mark the parts.

Serialized parts require different identification than non-serialized parts.

The bar code shall be on the part itself or on one or more data plates/labels, depending on shape and technical

constraints.

There are two categories of parts: Serialized and Non-Serialized, each having different data requirements. See
following outline:
