NOT
INCLUDED - REQUIRED TEST SLIDE: The HSE/NPL MarkII Phase Shift test slide
checks or standardizes the visual detection
limits of the phase contrast microscope. The HSE/NPL test slide consists
of a conventional microscope slide
with seven sets of parallel line pairs of decreasing widths. The microscope
must clearly resolve line pairs
1-3. Line pairs 4-5 must be at least partially visible. Line pairs 6-7
must be invisible. A microscope which fails
to meet these requirements is either too low or high in resolution and
cannot be used for asbestos identification. The
items marked with the asterisk (* ) are included in all MT6520 and MT6530
Series Models
Asbestos
Fiber Counting by Phase Contrast Microscopy
Methodology for PCM Analysis:
NIOSH 7400 & OSHA ID160 Phase contrast microscopy
is the method that is primarily used for estimating asbestos concentrations
of airborne fibers. This method is quick and can be performed on-site for
a rapid determination of concentrations of asbestos fibers in the air.
Phase contrast microscopy does not positively differentiate between asbestos
and other fibers. Positive identification of asbestos fiber must be performed
using PLM (Polarized Light Microscopy) or Electron Microscopy (Method 7402)
Required Microscope Equipment Positive phase contrast
microscope with 10X Brightfield and 40X Phase objectives, GIF (Green Interference
Filter), Walton & Beckett reticle Type-22G and a stage micrometer with
0.01mm divisions.
Required Test Slide The HSE/NPL Mark II Phase
Shift Test Slide checks or standardizes the visual detection limits of
the phase contrast microscope. The HSE/NPL Test Slide consists of a conventional
glass microscope slide with seven sets of parallel line pairs of decreasing
widths. The microscope must clearly resolve line pairs 1 thru 3. Line pairs
4 and 5 must be at least partially visible. Line pairs 6 and 7 must be
invisible. A microscope which fails to meet these requirements is either
too low or too high in resolution and cannot be used for asbestos detection.
