PRODUCT DESCRIPTION

COMPUTED RADIOGRAPHY IMAGING SYSTEM

1.0 SCOPE. This Product Description (PD) provides the minimum requirements for a Computed Radiography (CR) digital radiographic imaging system suitable for Nondestructive Inspection of a variety of metallic and non-metallic products used in military aircraft maintenance environments, which may be located at fixed military bases or deployed to austere forward operating locations. These imaging systems shall directly digitize and process radiographic images recorded on both hard and flexible Imaging Plates (IPs). The method of performing radiography shall be by using a storage phosphor system on both hard and flexible IPs. This PD provides for production evaluation as described herein.

2.0 CLASSIFICATION. The system described in this PD is classified as a complete CR system, employing state of the art photostimulable phosphor IPs as the collection media for radiographic data in the same manner as chemically-processed x-ray film used for the purpose of nondestructive inspection/testing/evaluation, except that these IPs shall be capable of being erased and re-used. An automated, programmable method of extracting the data and subsequently erasing the IP; and a method for displaying and storing the images shall be provided.

2.1 This PD contains system specifications necessary to meet Department of Defense (DoD) requirements for radiographic detection of foreign objects, water entrapment, and alignment (i.e., general purpose use) at 2.5 line pairs per millimeter (lp/mm), fatigue crack detection at 6.0 lp/mm, and welder certification at 8.0 lp/mm, in both the scanning and transverse directions using the process control devices described in paragraph 5.6.

2.2 The CR system shall be a table-top, portable CR system with Integral Eraser capable of processing industry standard flexible IPs from 5” x 7” to 14” x 17”, as well as custom sized flexible IPs as small as 2” x 4” and Original Equipment Manufacturer (OEM)-specific hard cassettes. Metric equivalent IP sizes are acceptable.

In the free beam area, the exposure shall result in 80-90% of the maximum achievable mean linear PV. Erase the IP. Scan the IP after erasure. Document the orientation of the IP during exposure and processing on the technique. Ensure the same orientation is maintained for subsequent tests. Erasure shall be calculated by the PV difference method. Erasure shall be calculated from the image taken as a result of scanning the erased IP. Determine the PV difference between the mean linear PV of the free exposed area and the mean linear PV of the area covered by the absorber. The ROI for each area should cover as large a region as possible within each area. The PV difference divided by the maximum achievable PV shall be ≤ 2%. Perform this test a total of 10 times. Upon completion of the test, any residual image with a PV difference divided by the maximum achievable PV above the allowed 2% shall be re-evaluated by repeating the tests with another IP.

Any residual image with a PV difference divided by the maximum achievable PV above the allowed 2% on the second IP is cause for rejection.

5.9.4 Successful completion of TO 1B-52H-36, Wing Trailing Edge Flaptrack Inspection.

Failure to visualize the 2-2T hole in the image quality indicator is cause for rejection.

5.9.5 Successful completion of TO 1C-130A-36, Aft Fuselage Side Structure from FS 770 to 968 (Tube Attach Fittings). Failure to visualize the 2-2T hole in the image quality indicator is cause for rejection.

5.9.6 Successful completion of TO 1F-15A-36, Tip closure rib (P/N 68A115105, without straps) for cracks, L/R first ramp rib support (P/N 68A327122), and L/R horizontal stabilator inboard leading edge rib (P/N 68A210130) for cracks. Failure to visualize the 2-2T hole in the image quality indicator is cause for rejection.

5.9.7 Successful radiographic inspection of a government owned welder certification tube butt joint weld specimen that contains porosity weld defects using existing T.O. 00-25-252 procedures. Failure to visualize defects, equivalent to film radiograph provided by the government, is cause for rejection.
