Full title and description

ISO 8843:2005/Amd 1:2012 — Aircraft — Crimp-removable contacts for electrical connectors — Identification system (Amendment 1). This one-page amendment (published September 3, 2012) modifies and clarifies aspects of the identification system for crimp-removable contacts defined in ISO 8843:2005.

Abstract

ISO 8843:2005 establishes a colour-band identification system for crimp-removable contacts used in aircraft electrical connectors. The system normally uses two colour bands on the external diameter of the crimp barrel and, for thermocouple or high-temperature contacts, additional letters or a colour point; further means (for example to indicate cable size or material) may also be used. Amendment 1 (2012) applies changes to the 2005 edition.

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 01.070 (Colour coding); 49.060 (Aerospace electric equipment and systems).

• Number of pages: 1 (amendment document).

Scope

This amendment applies to ISO 8843:2005 and addresses the identification system for crimp-removable contacts for electrical connectors used in aircraft and aerospace applications. The underlying standard defines the two-colour-band marking method and supplementary markings (letters or colour points) for thermocouple/high-temperature contacts; the amendment provides corrections/clarifications to that system.

Key topics and requirements

• Colour-band identification: two colour bands around the external diameter of the crimp barrel to identify contact types and characteristics.
• Thermocouple / high-temperature marking: use of additional letters or a coloured point to distinguish thermocouple contacts.
• Applicability: system applies to ISO standard contacts and is recommended for both preferred and non-preferred contact types.
• Allowance for additional identification: the standard permits supplementary identification means to convey parameters such as cable size or material.
• Editorial/technical updates: Amendment 1 (2012) provides the formal updates to the 2005 edition (minor technical or editorial changes captured in a one-page amendment).

Typical use and users

Used by aerospace manufacturers, electrical connector and contact designers, connector suppliers, maintenance/repair organisations, procurement and quality engineers responsible for component identification and interchangeability in aircraft electrical systems. The standard is maintained by ISO/TC 20/SC 1 (aerospace electrical requirements).

Related standards

Relevant or complementary documents include standards on colour coding and thermocouple connector/cable identification (for example IEC/ISO documents addressing thermocouples and colour codes and other aerospace connector specifications). Users often consult ISO 3864 (safety colours / signs), IEC/ISO thermocouple standards (colour coding) and other aerospace connector/product standards when implementing marking schemes.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2012) to ISO 8843:2005, which updates the identification system for crimp-removable contacts used in aircraft electrical connectors.

Q: What does it cover?

A: The underlying standard specifies a colour-band marking system (two bands on the crimp barrel) and supplementary markings (letters or colour points) for thermocouple or high-temperature contacts; the amendment provides clarifications or minor changes to that system.

Q: Who typically uses it?

A: Aerospace manufacturers, connector and contact suppliers, design and quality engineers, and maintenance organisations that need unambiguous identification of interchangeable crimp contacts.

Q: Is it current or superseded?

A: ISO 8843:2005 with Amendment 1 (2012) is recorded as published in the ISO catalogue; no later full revision of ISO 8843 is listed in the ISO entries consulted (i.e., the 2005 edition plus the 2012 amendment remain the published documents). Users should check the ISO catalogue or their national standards body for any subsequent revisions or national adoptions.

Q: Is it part of a series?

A: It is a standalone identification-system standard for crimp-removable contacts within the ISO/TC 20/SC 1 aerospace electrical requirements portfolio; related aerospace connector and colour-coding standards exist and are often used alongside ISO 8843.

Q: What are the key keywords?

A: Crimp-removable contact, identification system, colour band, thermocouple marking, aerospace connectors, ISO 8843, amendment 2012.
