For specific precautionary statements, see Section It is the responsibility of the user of this standard to establish appropriate safety atsm health practices and determine the applicability of regulatory limitations prior to use.

In this guide, the spectrometric methods are classified as quantitative, whereas the methods that yield indirect readings are termed qualitative. These practices typically involve standard chemical analyses and physical tests to meet product acceptance standards, e14476 are slow.

It summarizes the operating principles of each method, provides guidance ashm where and how each may be applied, gives when applicable qstm 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. This involves the use of standard quality assurance practices and procedures throughout the 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

Nondestructive means are available to supplement conventional metals grade verification techniques, and to monitor chemical and physical properties at selected production asttm, in order to assist in maintaining the identities of metals and their consistency in mechanical properties. Referenced Documents purchase separately The documents listed ee1476 are referenced within the subject standard but are not provided as part of the standard.

It describes the general requirements, methods, and procedures for the nondestructive identification and sorting of metals. A more comprehensive verification of product properties is necessary.

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.

Several pieces from a production run are usually destroyed astj rendered unusable through mechanical and chemical testing, and the results are used to assess the entire lot using statistical methods.

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.
