Scanning Acoustic Tomography is a non-destructive technique that analyses the structural composition of a material. It is used to detect hidden defects and voids in materials. It provides three-dimensional images.
Scanning Acoustic Tomography Technique
A specimen’s structural composition can be determined through scanning acoustic tomography. In this test, sound waves are focused on the specimen through transducers. The resulting speed and energy of the reflected wave are measured to determine the structural properties of the specimen. The test is also called Scanning Acoustic Microscopy (SAM) and Acoustic Micro Imaging (AMI).
This failure analysis technique is utilized to detect and procure three-dimensional images of structural faults, voids, cracks, abrasion, etc. in electronic components, ceramics, resins, and metals. In terms of resolution, scanning acoustic tomography provides a lateral resolution lower than 30 μm and a vertical resolution of a few nanometers.

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.
