NY ELAP 198.1


Asbestos testing is a vital process in the field of public health and safety. Among the various testing methods, the NY ELAP 198.1 stands out for its specific application and methodology. This guide will explore the details of this method.

What is the NY ELAP 198.1 Testing Method?

The NY ELAP 198.1 method is a specialized procedure that uses Polarized Light Microscopy (PLM) for the analysis of asbestos in building materials. This method is particularly effective for samples with high concentrations of asbestos.

How the NY ELAP 198.1 Testing Method Works

For samples with high concentrations of asbestos, the NY ELAP 198.1 method employs a stratified point-count technique. When asbestos concentrations are near the 1% level, a full 400-point count regiment is required, ensuring a thorough and accurate analysis.

Applicability of the NY ELAP 198.1 Testing Method

The NY ELAP 198.1 method is applicable to a variety of bulk materials. However, it's important to note that this method is not suitable for certain materials such as VAT, resilient floor tiles, mastic, asphalt shingles, roofing materials, paint chips, caulking, glazing, and other NOB materials. These materials require different testing methods for accurate asbestos detection such as the NY ELAP 198.4 method or the NY ELAP 198.6 method.

Sample Retention Time

Samples are retained for a period of 60 days.
