Anotace

Previously only available as film reference radiographs (ASTM RRE0272) these images are now available in a digitized format. Standard Digital Reference Images for High-Strength Copper-Base and Nickel-Copper Alloy Castings includes one DVD which contains an installer application that will install the binary data files and image processing application to generate the digital reference images. The image processing application can generate 16-bit TIFF or DICONDE image files in either negative (film-like) or positive pixel value normalization. Each data file generates one image that is analogous to a category page in the related film Reference Radiograph adjunct (see Scope section of related standard). The “category page” image combines the various severity level images (digital radiographs) into a single progress set with a solid black framing background that separates the individual digital radiographs. There is embedded annotation at the top of the single image in the black framing that includes embedded text annotations documenting the details of the image (such as ASTM standard number and pixel spacing selected during generation). The pixel values of the digital radiographs have been normalized so that the nominal background pixel value is around 32,000. The individual radiographs are generated from digitization data of the related film Reference Radiographs; the film Reference Radiographs were scanned at 5µm pixel spacing for high resolution. The radiographs represent 5 by 7-in. (127 by 178-mm) nominal size reproductions (twenty made for 1-in. (25.4-mm) plate castings exposed with low voltage X-rays for thicknesses up to and including 2 in.) and twenty-five made from 3-in. (76-mm) plate castings exposed with 2 MV X-rays or Cobalt 60 isotope for thicknesses greater than 2 in. up to and including 6 in. A copy of the current ASTM standard is included with the purchase of this product. System Requirements: PC Windows 7 or later 7-19 GB Hard Drive available 2 GB Memory (RAM + Virtual Memory) available.
