Railway transport equipment. Clevis and tenon joints. Fixed pins type FS.

This document outlines technical specifications for connecting components used in railway rolling stock. It focuses specifically on fork-type joints and mortise joints designed to accommodate fixed pin types designated as FS. The standard establishes precise geometric dimensions, material requirements, and performance criteria to ensure the structural integrity and safe operation of these critical interface points within rail transport systems. By defining standardized procedures for manufacturing and inspection, it facilitates interoperability between different manufacturers and ensures consistency across the railway network. Adherence to these guidelines helps maintain the reliability of mechanical connections under various operational conditions, contributing to the overall safety and efficiency of rail transit. The document serves as a reference for engineers and technicians involved in the design, production, and maintenance of railway equipment, providing clear criteria that must be met during the development and testing phases of relevant components.
