Full title and description

ISO 8056-2:1988/Amd 1:2016 — Aircraft — Nickel-chromium and nickel‑aluminium thermocouple extension cables — Part 2: Terminations — General requirements and tests — Amendment 1. This amendment updates and clarifies requirements and test conditions that apply to the crimped, non‑insulated terminations used with nickel‑chromium and nickel‑aluminium thermocouple extension conductors for aerospace applications.

Abstract

This document is Amendment 1 (published July 2016) to ISO 8056‑2:1988. It supplies limited, targeted changes to the Part 2 requirements and test methods for terminations of Ni–Cr and Ni–Al thermocouple extension cables (for example clarifications of test conditions, terminology and mechanical test limits) without replacing or reissuing the base standard text. The amendment itself is a short, one‑page technical change.

Scope

This amendment applies to ISO 8056‑2:1988 (Part 2 — Terminations). The base Part 2 standard defines design requirements and tests for crimping non‑insulated Ni–Cr and Ni–Al terminations to the flexible conductors of thermocouple extension cables so that thermoelectric integrity and resistance stability remain within specified limits; the amendment provides clarifications and technical adjustments to those termination requirements and test procedures. The base series (Part 1 and Part 2) covers conductors and terminations used in aircraft temperature measurement and control systems.

Key topics and requirements

• Applies specifically to terminations (crimped, non‑insulated) for nickel‑chromium and nickel‑aluminium thermocouple extension conductors used in aircraft systems.
• Clarifies test conditions and environmental parameters for reproducible testing (examples in amendment summaries include standard laboratory temperature and pressure constraints for tests).
• Updates or confirms mechanical test requirements (for example pull‑off load minima and related mechanical integrity checks) and refines relevant test procedures to ensure thermoelectric continuity is maintained after termination.
• Terminology and normative reference alignment so the Part 2 termination tests are consistent with aerospace electrical requirements under ISO/TC 20/SC 1.

Typical use and users

Used by aerospace OEMs and subcontractors, thermocouple and cable manufacturers, test laboratories, maintenance/repair organizations and procurement/specification engineers who need to produce, test or specify Ni–Cr / Ni–Al thermocouple extension cables and their terminations for aircraft applications. The amendment is consulted when precise test procedures or clarified termination requirements are needed.

Related standards

Primary related documents and equivalents include the base standard ISO 8056‑2:1988 (Part 2: Terminations) and ISO 8056‑1:1985 (Part 1: Conductors). Normative cross‑references for crimped joints used in aircraft electrical cables (for example ISO 1966) are typically cited in the Part 2 text. National/adopted equivalents and related standards (for example BS equivalents) exist and have been updated to reflect the amendment where applicable.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2016) to ISO 8056‑2:1988, the Part 2 specification for terminations of nickel‑chromium and nickel‑aluminium thermocouple extension cables used in aircraft. The amendment provides targeted changes and clarifications to the original 1988 Part 2 text.

Q: What does it cover?

A: It covers requirements and tests for crimped, non‑insulated terminations on Ni–Cr and Ni–Al thermocouple extension conductors — specifically ensuring mechanical integrity and the preservation of thermoelectric characteristics of the thermocouple circuit; the amendment refines and clarifies those test conditions and requirements.

Q: Who typically uses it?

A: Aerospace manufacturers, cable and termination component suppliers, test laboratories, maintenance and repair organizations, and specification/procurement engineers for aircraft temperature measurement systems.

Q: Is it current or superseded?

A: The document is an amendment published in July 2016 and is published as part of the ISO record for ISO 8056‑2:1988; the base Part 2 standard remains published (the amendment does not by itself supersede the base text but modifies it). Check national standards bodies or ISO for any later revisions or confirmations.

Q: Is it part of a series?

A: Yes — ISO 8056 is a small series covering thermocouple extension cables: Part 1 (Conductors — ISO 8056‑1:1985) and Part 2 (Terminations — ISO 8056‑2:1988), with this document being Amendment 1 to Part 2.

Q: What are the key keywords?

A: thermocouple extension cable; nickel‑chromium; nickel‑aluminium; termination; crimp; aerospace; test methods; thermoelectric integrity.
