Focal spots of industrial X-Ray tubes are measured by pinhole imaging, using ASTM E1165 standard test method. This test method specifies the process to determine the size of standard and mini focal spots in industrial X-ray tubes with focal spot dimensions ranging from 100 m to several mm and a tube voltage of 600 kV. Values expressed in SI units are considered standard.
The standard test method ASTM E1165 permits the user to determine the X-ray source’s adequate focal size. The reference to the object and object-to-detector distances are calculated, which is appropriate for preserving the desired degree of geometric unsharpness, maximum magnification, or both for a specific radiographic imaging application. The test can also assess if there has been a change in the tube overloading and focal spot size owing to tube aging.
The ASTM E1165 test method uses a pinhole camera to produce a picture of the focal spot. The size of the focal point from this image is measured. The size of the focal point is estimated by using the X- and Y-dimensions of the edge unsharpness. The geometrical picture and the sharpness values at given magnifications correlate to the measured effective spot sizes.
The angle between the pinhole axis and the beam direction must be less than 61.5°.
The result report in ASTM E1165 testing should include: The image name, machine model number and serial number, X-ray tube serial number, focal spot(s) measured, set-up and exposure parameters, date, organization name, and expected beam time hours.
The standard test method ASTM E1165 permits the user to determine the X-ray source’s adequate focal size.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
