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.

...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
