SIRTEF has got inside personnel qualified by the CICPND and certified at the 2nd level to make Non-Destructive Controls on steel wire ropes, slings and lifting accessories with the following methods:
Penetrating Liquids
This kind of control is carried out to highlight defects on surfaces of any kind of material (castings, welding, pipes, etc.). The non-destructive test method with penetrating liquids is based on visual examination of the surface after the application, in sequence, of a penetrating product and a detector one.
The method makes all discontinuities visible on the surface as they normally are not visible or are hardly visible to the naked eye instead. Here below technical details:
- Controllable surfaces:
Actually, all non-porous surfaces, areas without grooves or areas able to absorb penetrating liquids. - Detectable Defects:
Surface defects such as cracks, porosity, folds and incisions - Functionality:
Easy to use – applicable on site – sensitive to even apparently un-significant defects - Application:
Surface controls on non-porous materials

Magneto-scope Control
This kind of control is based on the deviation the magnetic field lines, as being induced in a ferromagnetic material, undergo at the presence of some discontinuity.
It is used in the control of welding, castings, etc.
- Detectable Features:
Magnetic flow dispersed due to superficial or sub-superficial discontinuities such as: cracks, cavities and inclusions - Functionality:
Sensitive to both surface and sub-surface defects - Application:
Surface and sub-surface controls on all ferromagnetic materials
