SIST EN 818-3:2001/oprA1:2006

Short link chain for lifting purposes - Safety - Part 3: Medium tolerance chain for chain slings - Grade 4

This Part of EN 818 specifies the requirements related to safety for short link lifting chains, Grade 4, of medium tolerance for use in chain slings and for general lifting purposes. The standard is applicable to electrically welded round steel short link chains, conforming to EN 818-1, which are intended for lifting objects, materials or goods.  The range of nominal sizes of chain covered by this Part of EN 818 is from 7 mm to 45 mm.  The hazards covered by this Part of EN 818 are identified in clause 4.  Annex A contains the bases for calculation of tabulated values for dimensions, working load limits and mechanical properties.  Annex B gives information on the mass/metre of chain.  Annex C gives an example of a designation system for chains of grade 4.  Annex ZA gives the relationship with EU-Directives

Overview

EN 818-3:1999/prA1 - Short link chain for lifting purposes – Safety – Part 3 defines safety requirements for medium tolerance short link chains (Grade 4) used in chain slings and general lifting. Published by CEN, this Part applies to electrically welded round steel short link chains (conforming to EN 818-1) intended to lift objects, materials or goods. The standard covers nominal chain sizes from 7 mm to 45 mm and includes normative/ informative annexes for calculation, mass per metre and designation. Annex ZA links the standard to relevant EU Directives.

Key topics and requirements

• Scope and applicability: Medium tolerance short link chains, Grade 4, for lifting and sling applications; nominal sizes 7–45 mm.
• Materials & heat treatment: Two material routes are allowed:
  • Steel meeting clauses 5.3.1 with heat treatment per 5.3.2; or
  • Austenitic stainless steel per EN 10088-3 (when used, chain must be solution annealed prior to manufacturing proof force and meet the specified mechanical properties).
• Mechanical properties & working load limits: Bases for calculation of dimensions, Working Load Limits (WLL) and mechanical properties are provided in Annex A.
• Mass/data: Annex B supplies mass-per-metre information to support design and procurement.
• Designation: Annex C shows an example designation system for Grade 4 chains.
• Safety & hazards: Hazards addressed by the Part are identified in clause 4 (see standard for details).
• Instructions/Information: Clause 9 provides user information (title revised from “Instructions” to “Information” in the amendment).
• Standards coordination: References updated (e.g., EN 292 replaced by EN ISO 12100-1/2 in the amendment).

Practical applications

• Use for designing, manufacturing, testing and specifying chain slings and lifting assemblies where medium tolerance Grade 4 short link chain is required.
• Applicable across industries performing heavy lifting: construction, manufacturing, warehousing, maritime and port operations, plant maintenance and material handling.
• Useful for preparing technical data sheets, compliance documentation and procurement specifications that reference EU safety requirements.

Who should use this standard

• Chain manufacturers and heat-treatment facilities
• Lifting equipment designers and engineers
• Safety managers, inspectors and test laboratories
• Procurement and quality assurance teams specifying lifting components
• Regulatory and compliance professionals ensuring conformity with EU Directives

Related standards

• EN 818-1 (general requirements for short link chains)
• EN ISO 12100-1 / EN ISO 12100-2 (machine safety - risk assessment and reduction)
• EN 10088-3 (stainless steel specifications)

For exact test procedures, hazard listings and numerical WLL tables refer directly to EN 818-3:1999/prA1 and its annexes.
