Overview
EN 1677-4:2000+A1:2008 is a CEN harmonized safety standard for components for slings – Part 4: Links, Grade 8. It specifies requirements for forged or welded steel master links, intermediate master links, master link assemblies and lower terminal links of Grade 8 with working load limits (WLL) up to 132 t. The standard is intended mainly for use in chain slings (EN 818-4), steel wire rope slings and textile slings (EN 1492‑1 / EN 1492‑2). It excludes hand‑forged links and aligns with EU Machinery Directive requirements via Annexes ZA/ZB.
Key Topics
- Scope and components covered: Grade 8 master links, intermediate links, assemblies and lower terminals up to 132 t WLL.
- Design and dimensions: Dimensional rules and articulation requirements (internal length/width) are specified so links fit and load is transmitted correctly; separate provisions exist for parallel‑sided and pear‑shaped links.
- Materials and metallurgy:
- Steel must be produced by electric or oxygen processes and fully killed.
- Aluminium content and grain size requirements to avoid strain‑age embrittlement (Al ≥ 0.025% and ISO 643 grain size).
- Chemical limits for sulfur and phosphorus are defined (tight cast/check limits).
- Minimum alloying element levels (e.g., Ni, Cr, Mo) are required to achieve mechanical and low‑temperature ductility across −40 °C to +400 °C.
- Heat treatment and mechanical properties: Hardened and tempered links must meet specified tensile, proof and elongation requirements.
- Manufacturing control and testing:
- Type tests, manufacturing proof tests and destructive tests (breaking force) are defined.
- Non‑destructive inspections referenced (EN 10228 series) and sample regimes for lots.
- Competent personnel and traceability code/lot marking requirements.
- Safety hazards and mitigation: Addresses load release, incorrect fitting, sharp edges, wear/corrosion and other risks identified in clause 4.
- Marking and documentation: Mandatory marking, manufacturer’s certificate and instructions for use are required.
Applications and Users
- Practical uses: design, manufacture, procurement and inspection of sling links for lifting operations in construction, shipping, heavy industry, manufacturing and logistics.
- Primary users: sling manufacturers, lifting equipment designers, PPE/lifting safety engineers, third‑party inspectors, and safety compliance officers ensuring conformance to CEN and EU Machinery Directive requirements.

4 Hazards Accidental release of a load or, release of a load due to failure of a link puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. In order to provide the necessary strength and durability of links, this Part of EN 1677 gives requirements for the design, manufacture and testing to ensure that specified levels of performance are met. Since failure can be caused by the incorrect choice of grade and specification of link, this Part of EN 1677 also gives requirements for marking and the manufacturer’s certificate. Errors in fitting can also lead to failure and this Part of EN 1677 contains dimensional requirements to allow correct fit. Risk of injury due to sharp edges, sharp angles or rough surfaces when handling is also covered by this standard. Those aspects of safe use associated with good practice are given in prEN 818-6:1999. Table 1 contains those hazards which require action to reduce risk identified by risk assessment as being specific and significant for links of grade 8.

Parts of integral joining devices, such as pins and their securing elements, shall be so designed and manufactured that, after assembly, no unintended displacement can occur. NOTE The effects of wear, corrosion of securing elements or rough usage should be considered. 5.2 Dimensions The internal dimensions of links covered by this part of EN 1677 shall be such as to ensure articulation so that the force imposed is transmitted in the intended direction. The cross-section of links shall be so as to conform to 5.5. NOTE This requirement permits a varying shape and area of cross-section. The internal length and internal width of parallel sided master links shall be as in table 2.
