Which size of radiographic film should I select?
In this article:
- Radiographic Film Sizes Follow ISO 5565 Standards: The article outlines how industrial radiographic film sizes are largely standardized under ISO 5565, ensuring compatibility and consistency across inspection applications
- Standard and Custom Film Sizes Are Available: While standard sizes are widely used, non-standard and custom-cut films can be supplied for specific inspection needs, such as unique weld lengths or vessel circumferences
- Vacuum-Packed Film Reduces Fault Risk: Films and metal screens can be vacuum-packed together to minimize the risk of film faults caused by environmental exposure or handling
- Rollpac Strip Film Offers Flexibility for Weld Inspections: For large-scale weld inspections, Rollpac film—available on rolls with integrated lead screens—can be pre-cut to match specific project dimensions
- Film Size Selection Depends on Application Scope: Choosing the right film size depends on the geometry of the object being inspected, the required image resolution, and the inspection environment
Which size of radiographic film should I select?
Film sizes in industrial radiography are to a large extent standardised according to ISO 5565. Non-standard sizes are possible. Standard film sizes and metal screens are supplied separately, but can also be supplied vacuum-packed so that the risk of film faults is considerably reduced. For weld inspection there is so-called Rollpac film strip on the market which is available on a roll together with the lead screen.
For very large projects the strip film can even be pre-cut to suit a particular weld length or pipe/vessel circumference.
