1.1 这些数字参考图像阐明了铝合金铸件中可能找到的不连续的种类和程度。所阐明的铸件厚度为1/4 in.(6.35 mm)和3/4 in.(19.1 mm)。
1.2 本标准的所有领域对审理工程组织和供应商之间的协议,或对来自审理工程组织的特定方向,是开放的。这些条款应在购买订单或合同中得到解决。
1.3 英制单位规定的数值被视为标准值。圆括号中给出的数值为数学转换后的国际单位,仅作为信息提供,而不被认为是标准值。
1.4 在进行射线照相时,这些数字参考图像的目的并非是阐明铝合金铸件中找到的不连续的种类和程度。如果铝合金铸件进行射线照相,参看参考照片E155。
1.5 本标准未能详细列明所有与其用途相关的安全问题(如有)。本标准的使用者在使用前有责任确立合适的安全健康规程,并确定法规限制的适用性。
1.6 仅获得许可的软件和图像副本可用于产品检验。为了审计的目的,ASTM/用户许可协议的副本应存档。
注1:一套数字参考图像由13个数字文件,用于加载需要格式的软件和加载过程中的具体说明组成。这13个参考图像阐明了八个等级的严重程度,并含有一张阶跃式光楔和两个线对计量器的图像。可从ASTM国际总部获得,订单号:RRE02422。对于线对计量器的细节,参看规程E2002。
注2:适用于厚度高达1 in.(25 mm)的铝和镁压铸件的参考照片被包含在参考照片E505中。
Thirteen digital reference images, previously only available as film reference radiographs (ASTM E155), are now available in a digitized format.
The images illustrate the types and degrees of discontinuities that may be found in aluminum-alloy castings. This 2 DVD set consists of the 13 digital files, software to load the desired format, and specific instructions on the loading process.
One DVD provides seven digital images of 1/4 inch (6.35 mm) castings; and the second DVD provides six digital images of 3/4 inch (19.1 mm) castings. These images illustrate eight grades of severity and contain an image of a step wedge and two line pair gages.
A copy of the current ASTM standard is included with the purchase of these reference radiographs.
The images may be installed as 16-bit TIFF files or as DICONDE files and may be installed for negative or positive image polarity. The images may be installed at resolutions to match the effective resolution of various digital detectors in increments of 10 microns.
Price for single-site users.
To order, contact Customer Service or call 1-877-909-ASTM.
