ASTM E1806-96(2006)

ASTM E1806-96(2006) - 1.11.2006

Significance and Use

This practice covers all aspects of sampling and preparing steel and iron for chemical analysis as defined in Test Methods, Practices, and Definitions A 751 and Specification A 48/A 48M. Such subjects as sampling location and the sampling of lots are defined.

It is intended that this practice include most requirements for sampling steel and iron for analysis. Standard analytical methods that reference this practice need contain only special modifications and exceptions.

It is assumed that all who use these procedures will be trained samplers capable of performing common sampling operations skillfully and safely. It is expected that only proper sampling equipment will be used.

1. Scope
