Asbestos Testing

Asbestos PLM
The analysis includes testing of bulk building materials for asbestos by performing a visual estimation using the EPA Method 600/R-93/116. This method is the most widely used method for estimating asbestos in bulk building materials and works well for most sample types. However, it might require a more detailed method like point counting for accurate estimation of asbestos in samples with low asbestos concentration. This method is also not applicable for samples containing large amounts of fine fibers below the resolution of the PLM (< 0.3 microns). The method separates the sample material into various layers based on their morphology and then detects for the presence of the different asbestos fibers in each of these layers. The report will express the percentage of the different asbestos fibers detected in each of the different layers based upon the visual estimation.  More details...

Asbestos-airborne fiber count (NIOSH 7400)
The analysis includes testing of air samples by Phase Contrast Microscopy (PCM). It is used primarily for estimating fiber concentrations in air. Results can be used to show compliance with limits set by NIOSH, OSHA, and other regulatory agencies. The method does not differentiate between asbestos fibers and other fibers. Fibers less than 0.25 microns in diameter will not be detected with this method.  More details...
Asbestos-CARB 435
The analysis includes testing of rocks (and soils) for asbestos using the California Air Resource Board 435 method. The CARB 435 method is a specialized method used for testing asbestos content in the serpentine aggregate storage piles, on conveyer belts, and on covered surfaces such as roads, play-yards, shoulders and parking lots. The method requires crushing the sample using a mill to produce a sample size of less than 200 tyler mesh (75 microns) and then reporting the asbestos content by performing a 400 point count technique which has a detection limit of 0.25%.  More details...
Asbestos-CARB 435 (pre-crushed)
The analysis includes testing of rocks (and soils) for asbestos using the California Air Resource Board 435 method. The CARB 435 method is a specialized method used for testing asbestos content in the serpentine aggregate storage piles, on conveyer belts, and on covered surfaces such as roads, play-yards, shoulders and parking lots. The method requires crushing the sample using a mill to produce a sample size of less than 200 tyler mesh (75 microns) and then reporting the asbestos content by performing a 400 point count technique which has a detection limit of 0.25%.  More details...
Asbestos-EPA 1000 point count
The analysis includes testing of bulk building materials for asbestos by performing 1000 point counts (EPA 600/R-93/116). This is a detailed and more labor-intensive technique for estimating asbestos in a building material and is less subjective than a visual estimate. While the visual estimation of asbestos in a building material works well for most samples, this methodology can be very important when low asbestos concentration in a building material is suspected or detected. This methodology, which has a detection limit of 0.1%, increases the accuracy and precision of the asbestos concentration determined in a sample.  More details...
Asbestos-EPA 200 point count
The analysis includes testing of bulk building materials for asbestos by performing 200 point counts (EPA 600/R-93/116). This is a detailed and more labor-intensive technique for estimating asbestos in a building material and is less subjective than a visual estimate. While the visual estimation of asbestos in a building material works well for most samples, this methodology can be very important when low asbestos concentration in a building material is suspected or detected. This methodology, which has a detection limit of 0.5%, increases the accuracy and precision of the asbestos concentration determined in a sample and is widely used to comply with NESHAP regulations requirement of performing point counting on samples with low concentrations of asbestos.  More details...
Asbestos-EPA 400 point count
The analysis includes testing of bulk building materials for asbestos by performing 400 point counts (EPA 600/R-93/116). This is a detailed and more labor-intensive technique for estimating asbestos in a building material and is less subjective than a visual estimate. While the visual estimation of asbestos in a building material works well for most samples, this methodology can be very important when low asbestos concentration in a building material is suspected or detected. This methodology, which has a detection limit of 0.25%, increases the accuracy and precision of the asbestos concentration determined in a sample and is widely used to comply with NESHAP regulations requirement of performing point counting on samples with low concentrations of asbestos.  More details...
Asbestos-gravimetric point count (sub-contracted)
The analysis includes an evaluation of bulk building materials for its organic components, inorganic acid-soluble and insoluble components and asbestos concentration based on 400 point counts (EPA 600/R-93/116). This is a detailed and more labor-intensive technique for estimating asbestos and other components in a building material and is less subjective than a visual estimate. This methodology, which has a detection limit of 0.25%, increases the accuracy and precision of the asbestos concentration determined in a sample. The report will express the percentage of the different asbestos fibers detected based upon the 400 point counts and also provide a percentage concentration of the organic, inorganic acid-soluble and insoluble components in the whole sample. This is a Sub-contracted Service (QA-7211 and 7450).  More details...
Asbestos-OSHA with TWA
The analysis includes testing of air sample for asbestos and other fibers by PCM via NIOSH 7400 and calculating the Time Weighted Average (TWA). TWA's are used for personnel sampling and the most common objective of performing a TWA sampling is for compliance with OSHA limits. More than one sample per individual is required to perform the TWA analysis. The results of the multiple samples per individual are combined to report the TWA.  More details...
Asbestos-TEM Qualitative P/A (sub-contracted)
Samples are prepped in the same manner as EPA Method 600/R-93/116 but analyzed using TEM instead of PLM. Results are reported as Presence/Absence as opposed to a percentage value as in the PLM method. This is a Sub-contracted Service (QA-7450).  More details...
