Significance and Use | ||||||||||||||||||
5.1?The methods described provide indirect measurement of the thickness of sections of materials not exceeding temperatures of 1200?F [650?C]. Measurements are made from one side of the object, without requiring access to the rear surface. 5.2?Ultrasonic thickness measurements are used extensively on basic shapes and products of many materials, on precision machined parts, and to determine wall thinning in process equipment caused by corrosion and erosion. 5.3?Recommendations for determining the capabilities and limitations of ultrasonic thickness gages for specific applications can be found in the cited references (1.1?This practice provides guidelines for measuring the thickness of materials using Electromagnetic Acoustic Transducers (EMAT), a non-contact pulse-echo method, at temperatures not to exceed 1200?F [650?C]. 1.2?This practice is applicable to any electrically conductive or ferromagnetic material, or both, in which ultrasonic waves will propagate at a constant velocity throughout the part, and from which back reflections can be obtained and resolved. 1.3?UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
