Overview

SIST EN 22340:1996 - Clevis Pins Without Head (ISO 2340:1986) is a European standard developed by CEN that specifies the properties and dimensional characteristics of clevis pins without a head. This standard covers products both without split pin holes (Type A) and with split pin holes (Type B) in metric sizes. Applicable nominal diameters range from 3 mm up to and including 100 mm, supporting versatility in various mechanical and engineering applications. SIST EN 22340:1996 references and aligns with International Standard ISO 2340:1986, ensuring international compatibility and uniformity.

Key Topics

• Product Types: Details two types of clevis pins:

  • Type A - Without split pin holes
  • Type B - With split pin holes

• Metric Dimensions: Specifies nominal diameters from 3 mm to 100 mm, facilitating diverse mechanical uses.

• Standardized Terminology: Provides clear designations and examples for each pin type and size to minimize ambiguity in supply chains.

• Reference to International Standards: Harmonized with ISO 2340:1986 for global compatibility, supporting cross-border manufacturing and sourcing needs.

Applications

Clevis pins without head, as defined by SIST EN 22340:1996, play a fundamental role across multiple industries due to their simplicity, strength, and standardization. Typical applications include:

• Machinery and Equipment: Used as pivot, hinge, or linkage pins in agricultural, construction, and industrial equipment.
• Automotive Sector: Integral in assembling and linking mechanical components where quick assembly and disassembly are required.
• Aerospace and Rail: Suitable for control systems and mechanical linkages, benefiting from standardized sizing and interchangeable parts.
• General Engineering: Preferred for assembling mechanical joints and temporary structural connections, owing to their reliability and ease of replacement.

The use of clevis pins standardized under SIST EN 22340:1996 ensures high levels of interchangeability, efficient maintenance, and compatibility between manufacturers and suppliers globally.

Related Standards

For broader perspective and integration, the following international and European standards are relevant to SIST EN 22340:1996:

• ISO 2340:1986 - Clevis pins without head, the international counterpart forming the technical basis for SIST EN 22340:1996.
• EN 22341 - Covers clevis pins with heads, offering a complementary specification.
• ISO 2341 - Specifies split pins suitable for use with Type B clevis pins.
• EN ISO 8752 - Relates to spring-type straight pins for secure fastening in similar applications.

Adopting SIST EN 22340:1996 facilitates harmonized procurement, production, and maintenance practices, ensuring compliance with European and international quality standards for clevis pins without head.
