AS 5370, 2024 – Sampling and qualitative identification of asbestos in bulk materials (ISO 22262-1:2012, MOD)

AS 5370:2024 is the Australian standard for the sampling and qualitative identification of asbestos in bulk materials. This standard adopts and modifies the ISO 22262-1:2012 standard. It provides detailed guidelines for the collection, preparation, and analysis of samples to detect asbestos fibers in various materials.

Key aspects covered by AS 5370:2024 include:

Sampling Procedures: The standard outlines methods for safely collecting representative samples, ensuring they are not contaminated during the process.
Sample Preparation: Techniques like ashing, acid treatment, and sedimentation are prescribed to prepare samples for analysis.
Analysis Techniques: The standard describes the use of Polarized Light Microscopy (PLM), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) for identifying asbestos fibers.
Reporting: It also details how the findings should be documented, including the preparation of test reports.

This standard supersedes AS 4964-2004 and represents the most up-to-date practices for asbestos identification in Australia, reflecting international best practices with modifications tailored to local requirements
