What is BS EN 13001‑3‑5 about?  
BS EN 13001‑3‑5 is to be used together with EN 13001-1 and EN 13001-2 and, as such, they specify general conditions, requirements, and methods to prevent by design and theoretical verification, mechanical hazards in crane hooks. Principles of BS EN 13001‑3‑5 can be applied to machined shanks of hooks in general.
BS EN 13001‑3‑5 is applicable to cranes, which are manufactured after the date of approval of BS EN 13001‑3‑5 by CEN, and serves as a reference base for product standards of particular.
BS EN 13001‑3‑5 covers the following parts of hooks and types of hooks:
- Bodies of any type of hooks made of steel forgings or steel castings, including stainless steel
- Machined shanks of hooks with a thread/nut suspension
Note 1: Plate hooks, which are those, assembled of one or several parallel parts of rolled steel plates, are not covered in BS EN 13001‑3‑5.
Note 2: This part of EN 13001 deals only with the limit state method in accordance with EN 13001–1
Who is BS EN 13001‑3‑5? 
BS EN 13001‑3‑5 on the competence of forged and cast hooks on cranes is applicable to: 
- Crane designers
- Crane manufacturers
- Crane operators 
- Safety regulatory bodies  
- End Users and consumers  
- Maintenance workers of crane 
Why should you use BS EN 13001‑3‑5?  
Cranes are large, powerful pieces of equipment that pose potential risks due to the fact that both the cranes and the weight they transport might inflict injury if not managed appropriately. As a result, critical safety rules must be followed in accordance with regulatory authorities.
BS EN 13001‑3‑5 provides a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse.
Hence, crucial safety guidelines in BS EN 13001‑3‑5 need to be followed which will reduce or eliminate the risks associated with the following hazards.
By adopting BS EN 13001‑3‑5 the manufacturers and designers can demonstrate the safety and effectiveness of forged and cast hooks. Adopting BS EN 13001‑3‑5 can reduce or eliminate the risks associated with the following hazards:
- Exceeding the limits of yield strength, ultimate strength, fatigue strength, brittle fracture
- Exceeding temperature limits of material
What’s changed since the last update? 
BS EN 13001‑3‑5:2016+A1:2021 supersedes BS EN 13001‑3‑5:2016, which is withdrawn.
The major changes in BS EN 13001‑3‑5:2016+A1:2021 compared to EN 13001-3-5:2016 are the inclusion of limit fatigue design stress, the basic fatigue strength of materials, and permanent marking of hook body to extend the scope of the standard to “cast hooks
