DIN 3090 1989-08 PDF

Full title and description

STB DIN 3090:1989-08 — Wire rope steel thimbles (German: Kauschen - Formstahlkauschen für Drahtseile). The document specifies dimensional, material and marking provisions for steel thimbles used to protect and retain the eye/loop of steel wire ropes.

Abstract

Specifies requirements for thimbles for use with wire ropes, including nominal sizes, basic dimensions, material and surface finish guidance; intended to ensure correct fit and protection of wire‑rope eyes used in lifting, mooring and general rigging applications.

General information

• Status: Superseded / withdrawn (cancelled and no longer current).
• Publication date: 1989-08-01 (edition referenced as 1989-08).
• Publisher: Deutsches Institut für Normung (DIN).
• ICS / categories: Accessories for lifting equipment — ICS 53.020.30 (relevant classification for rope accessories and lifting fittings).
• Edition / version: 1989-08 (single short edition).
• Number of pages: 2 pages (short technical specification).

Scope

Applies to steel thimbles intended for use with steel wire ropes to protect the rope eye from abrasion and deformation and to hold the correct bending radius at terminations. The standard covers nominal sizes, essential dimensions and general material/finish guidance needed to produce thimbles that mate correctly with specified rope diameters. It does not cover special thimbles for non‑steel (fibre) ropes or solid/reeving thimbles outside the stated nominal range.

Key topics and requirements

• Definition of nominal sizes and corresponding basic dimensions (groove width, outer width/length and clearances) for each rope diameter.
• Material specification: steel thimbles (forged or formed steel) with commonly required surface finishes (electro‑galvanized or hot‑dip galvanized) to resist corrosion.
• Marking and identification requirements (size marking to permit correct matching with rope).
• Tolerances and dimensional acceptance criteria to ensure interchangeability and fit with specified rope diameters.
• Notes on intended use: protection of rope eyes in lifting, mooring, rigging and general engineering applications (compatibility with associated fittings and safe assembly practice).

Typical use and users

Used by rigging and lifting equipment manufacturers, wire‑rope and sling fabricators, marine and offshore suppliers, inspection and maintenance personnel, and procurement teams requiring standardized thimbles for safety‑critical terminations and splices. Product engineers and safety officers consult the specification to verify correct thimble sizing and material/finish for specific rope applications.

Related standards

DIN 3090 has been superseded in practice by later European and international standards for wire‑rope terminations and thimbles; the EN/DIN EN 13411 series (particularly EN 13411‑1 covering thimbles) and ISO 2262 (general‑purpose thimbles) are the primary related documents to consult for current requirements and harmonized dimensions. Some national catalogues also show later replacements or national variants.

FAQ

Q: What is this standard?

A: DIN 3090:1989-08 is a short German standard that defined requirements for steel wire‑rope thimbles (protective fittings for rope eyes). It is a 2‑page technical specification published by DIN in August 1989.

Q: What does it cover?

A: It covers nominal sizes, basic dimensions, material and surface finish guidance, marking and dimensional tolerances for steel thimbles intended for use with steel wire ropes — in other words, the aspects needed to ensure correct fit and protection of rope terminations.

Q: Who typically uses it?

A: Manufacturers of thimbles and rigging hardware, wire rope and sling fabricators, lifting equipment suppliers, safety inspectors and engineers concerned with correct termination and protection of wire‑rope eyes.

Q: Is it current or superseded?

A: It is superseded/withdrawn and is no longer the current state of the art; EN/DIN EN 13411‑1 (and the EN 13411 series) and related national technical documents have effectively replaced DIN 3090 for modern, harmonized practice. Catalog and standards vendors list DIN 3090 as cancelled/replaced.

Q: Is it part of a series?

A: DIN 3090 itself was a standalone short specification for thimbles, but its subject matter is now covered within the EN 13411 series (terminations for steel wire ropes) and is related to international documents such as ISO 2262 for rope thimbles. For comprehensive current requirements, consult the EN 13411 parts and ISO 2262.

Q: What are the key keywords?
