The electromagnetic eddy current and thermoelectric methods, on the other hand, are among those that respond to properties in the sample that are affected by chemistry and processing, and they yield indirect information on composition and mechanical properties.

This involves the use of standard quality assurance practices and asm throughout atm various stages of manufacturing and processing, at warehouses and materials receiving, and during fabrication and final installation of the product.

ASTM E – 04() Standard Guide for Metals Identification, Grade Verification, and Sorting

It describes the general requirements, methods, and procedures for the nondestructive identification and sorting of metals. Spectrometric analysis instruments respond to the presence and percents of alloying constituents.

These practices typically involve standard chemical analyses and physical tests to meet product acceptance standards, which are slow. A more comprehensive verification of product properties is necessary. For specific precautionary statements, see Section 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.


Statistical quality assurance methods are usually effective; however, mixed grades, off-chemistry, and nonstandard physical properties remain the primary causes for claims in the metals industry. 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. Historical Version s – view previous w1476 of standard.

They are quite often used in the field for solving problems involving off-grade and mixed-grade materials. Several pieces from a production run are usually destroyed or rendered unusable through mechanical and chemical testing, and the results are used to assess the entire lot using statistical methods.

Nondestructive means are available to supplement conventional metals grade verification techniques, and to 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.

In s1476 guide, the spectrometric methods are classified as quantitative, whereas the methods that yield indirect readings are termed qualitative.
