Making ‘fit-for-purpose’ a reality
Functional and operational requirements and intended use provide relevant input for the design, manufacturing, testing and use of slings in ‘engineered’ lifting operations. So, it is not only about reaching a certain initial strength and/or proof load value.
This ‘fit-for-purpose’ approach, challenges the traditional ‘design factor’ method and implies more than just verifying the minimum breaking strength and/or the proof loading characteristics. This is far too often the only ‘verification’ used in the market today prior to handing over slings to the user.
NOTE: A ‘verification’ is not the same as ‘certification’, even though documents issued by certification authorities describing this verification is called a ‘Certificate’. Verification is solely focused on products’ properties based on engineering, manufacturing and integration of components prior to handing-over to the user. Certification focuses on these aspects as well as the application, operation and maintenance in the usage phase. So, certification is ‘service life’ focused. There is not just one way to certify a solution!
