This document specifies the minimum requirements for solid thimbles made of steel or cast iron for terminations of stranded steel wire ropes. This document is applicable to ferrule-secured terminations with solid thimbles in combination with ferrules according to EN 13411-3, that have an efficiency factor KT of at least 0,9, and to spliced terminations with solid thimbles according to EN 13411-2, that have an efficiency factor KT of at least 0,8, which are used as accessories for steel wire ropes, such as slings or wire rope assemblies, having a lifting, lowering or load-bearing effect in hoisting equipment. Examples of designs of solid thimbles are given in informative Annex B and C. Round thimbles are not subject to this document. This document is applicable to ferrule-secured terminations that are manufactured after the date of publication of this document. Hazards that are dealt with in this document are listed in Clause 4.

This document specifies the method for the verification of models for the determination of the property data of steels and the validation of the modelling process. It is applicable where modelling of mechanical or physical properties is used to substitute conventional testing for specific inspection. Models can be based on statistical data, thermo-physical data or indirect measurement (e.g. measurement of magnetic or ultrasonic data), or a combination of these methods.

This document applies only for providing the properties of rolled and/or heat-treated products such as plates, sheets, strip, sections and bars.

This document is used to demonstrate the ability of the model to supply property data which is equivalent to data, measured by conventional testing.

Any self-learning system is excluded from the scope.

NOTE A self-learning model is a model which changes its internal parameters by itself.

This document specifies the requirements for hot-rolled twin-roll cast steel sheet of commercial quality.

The product is intended for many applications where the presence of oxide or scale or normal surface imperfections disclosed after removal of oxide or scale, are not objectionable. It is not suitable for applications where the surface is of prime importance.

NOTE This document does not cover steel sheet that is to be subjected to subsequent rolling.
