Film Class Requirements

Is anyone aware if any of the ASME or ANSI codes specify what class of film is required to be used when radiographing welds. (ie; Kodak T class 1 whereas Kodak AA is class 2).

In my opinion as long as the film can meet the required sensitivity then the film is ok to use regardless of the class.

I know some customers request Class 1 film be used in many cases because its written in the client spec. but if it is not specified can you use Class 2 if it meets sensitivity requirements?

Any thoughts!

Re: Film Class Requirements
ASME Article 2 states that any class is acceptable, but the film must be classed in accordance with Article 22, SE-1815. I think the defining factor is the ability to meet the required sensitivity per Section 2. Other code sections and other codes may have differing requirements.

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
