Key principles and requirements
: Determining the ferrite or intermetallic (sigma phase) content in duplex stainless steels to ensure corrosion resistance and mechanical integrity.
If you are auditing to ISO 17025 or Nadcap, you must ensure you are using the most current revision—typically E562-19.
ASTM E562-19 is a standard practice that provides guidelines for stratified sampling of the environment. The standard practice is significant because it helps ensure that environmental sampling is conducted in a statistically valid and reliable manner. By following the guidelines outlined in ASTM E562-19, environmental professionals can increase sampling efficiency, improve data quality, and reduce uncertainty associated with environmental sampling.
As she was designing the alloy, Emma realized that she needed to ensure that it met the stringent quality standards of the industry. She spent hours poring over various ASTM standards, including ASTM E562-19, to understand the requirements for inclusion content.
