Standard test method ASTM E545-19 is used to determine Image Quality in Direct Thermal Neutron Radiographic Examination. An Image Quality Indicator (IQI) system is used to measure the relative quality of radiographic pictures produced by direct, thermal neutron radiography inspection. The values expressed in SI units should be considered standard.
The standard test method ASTM E545-19 is used to determine quantitative data on neutron beam and image system parameters that influence film exposure and, as a result, image quality. In addition, Beam Purity Indicator (BPI) is used to check the neutron radiography quality on a day-to-day basis. The BPI is developed and tested using gadolinium conversion screens and single-emulsion silver-halide films exposed combined in a neutron imaging beam.
In the ASTM E545-19 test, a beam of radiation is directed perpendicularly on the film plane. Firstly, a conversion screen is used that responds to neurons of thermal energy; exposure contributors are also calculated. Then, the value of G, H, and sensitivity level is determined. Finally, neutron radiography was determined, and images of wire were compared visually in BPI.
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 is a standard test method for the analysis of sulfochromate etches solution 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.
