Standard Guide for Metals Identification, Grade Verification, and Sorting
Nondestructive means are available to supplement conventional metals grade verification techniques, and d1476 monitor chemical and physical properties at selected production stages, in order to assist in maintaining the identities of metals and their consistency in mechanical properties. It describes the general requirements, methods, and procedures for the nondestructive identification and sorting of metals.
This involves the use of standard quality assurance practices and procedures throughout the atsm stages of manufacturing and processing, at warehouses and materials receiving, and during fabrication and final installation of the product. For specific precautionary statements, see Section Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Several pieces from a production run are usually destroyed or rendered unusable through mechanical and chemical testing, and the asstm are used to assess the entire lot using statistical methods.
In this guide, the spectrometric methods are classified as quantitative, whereas the methods that yield indirect readings are termed qualitative. It summarizes the operating principles of each method, provides guidance on where and how each may be applied, gives when applicable the precision and bias that may be expected, and assists the investigator in selecting the best candidates for specific grade verification or sorting problems.
Spectrometric analysis instruments respond to the presence and percents of alloying constituents. The electromagnetic eddy current and thermoelectric methods, on the other asym, are among those that respond to properties astmm the sample that are affected by chemistry and processing, and they yield indirect information on composition and mechanical properties.
They are quite often used in the field for solving problems involving off-grade and mixed-grade materials. Statistical quality assurance methods are usually effective; however, mixed grades, off-chemistry, and nonstandard physical properties remain the primary causes for claims in asstm metals industry. A more comprehensive verification of product properties is necessary.
These practices typically involve standard chemical analyses and physical tests to meet product acceptance standards, which are slow.
