Overview

SIST EN 12441-2:2004/A2:2005 is a key European Standard developed by CEN for the chemical analysis of zinc and zinc alloys, focusing specifically on the determination of magnesium content. This standard details the flame atomic absorption spectrometric (FAAS) method designed to accurately measure magnesium in zinc alloys. It serves as an amendment to the original EN 12441-2:2001 and is enforced across multiple European countries, ensuring harmonized analytical practices within the metals industry.

The FAAS technique outlined in this standard is recognized for its precision and reliability in detecting low concentrations of magnesium, crucial for maintaining alloy quality and performance. SIST EN 12441-2:2004/A2:2005 supports compliance with quality control, product certification, and regulatory requirements within zinc alloy production and testing laboratories.
