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.
