Full title and description

STB BS 3SP 170-171:2002 — Braided rubber cord assemblies for aerospace use. This standard specifies requirements for braided rubber cord assemblies intended for aircraft and aerospace applications, covering four defined types (heavy and light duty, cotton- and aramid‑covered) with associated ferrules and assembly wires manufactured from stainless or cadmium‑plated steel.

Abstract

This publication (BS 3SP 170-171:2002) defines dimensional, material and assembly requirements for braided rubber cord assemblies used in aerospace installations. It identifies two parts (170 and 171) that distinguish heavy‑duty and light‑duty types and specifies compatible ferrules and assembly wire construction and finish to ensure reliable service in aircraft environments.

Scope

The standard applies to braided rubber cord assemblies intended for aerospace use and covers four types: heavy‑duty cotton covered and heavy‑duty aramid fibre covered cords (BS 3SP 170) and light‑duty cotton covered and light‑duty aramid fibre covered cords (BS 3SP 171). It specifies acceptable cord constructions (referencing BS F 70 / F 70A and BS F 71 / F 71A), compatible ferrules and assembly wires (referencing BS SP 168‑169), and the permitted materials and finishes for metallic components (stainless steel or cadmium‑plated steel). The scope is limited to requirements for assemblies rather than broader material or manufacturing methods except where explicitly referenced.

Key topics and requirements

• Definition of four braided rubber cord assembly types: heavy‑duty cotton, heavy‑duty aramid, light‑duty cotton, light‑duty aramid.
• Reference to cord construction standards: BS F 70, BS F 70/A, BS F 71, BS F 71/A.
• Specification of ferrules and assembly wire to BS SP 168‑169 and acceptable metallic finishes (stainless steel or cadmium plated steel).
• Performance and interchangeability requirements appropriate for aerospace installations (dimensions, assembly integrity and material compatibility).
• Application‑level focus: ensures assemblies meet aerospace safety and serviceability expectations rather than providing broader material specifications.

Typical use and users

Typical users include aircraft manufacturers (OEMs), aerospace suppliers and component manufacturers, maintenance/repair/overhaul (MRO) organizations, procurement and quality assurance engineers, and design engineers specifying cable restraint, securing and elastic assemblies on aircraft. The standard supports selection, procurement and inspection of braided rubber cord assemblies used in aircraft systems.

FAQ

Q: What is this standard?

A: BS 3SP 170‑171:2002 is a British Standard that specifies requirements for braided rubber cord assemblies intended for aerospace use (two parts covering heavy and light duty variants).

Q: What does it cover?

A: It covers the types of braided rubber cords (cotton‑covered and aramid‑covered, heavy and light duty), required ferrules and assembly wire characteristics, and acceptable metallic materials/finishes for those assemblies, referencing related BS documents for cord and ferrule construction.

Q: Who typically uses it?

A: Aerospace OEMs, parts suppliers, MRO organizations, design and procurement engineers, and quality/inspection teams involved with aircraft component selection and acceptance.

Q: Is it current or superseded?

A: The document is listed as a published British Standard (status: standard / active) from 2002. Users should verify current status with BSI or an official standards distributor for the latest confirmation before procurement or normative referencing (this summary is based on available catalogue records).

Q: Is it part of a series?

A: Yes — the numbering indicates a two‑part designation (3SP 170 and 3SP 171) addressing heavy and light duty types respectively; it also cross‑references related BS documents for cord and ferrule specifications.

Q: What are the key keywords?
