Title
Standard Test Method for Equivalent Black Area (EBA) of Dirt in Pulp, Paper and Paperboard by Image Analysis
ASTM International
Publication Date:
Jul 10, 1997
Scope:
This test method covers the use of image analysis to determine the
level of dirt in pulp, paper,
and paperboard in terms of Equivalent Black Area (EBA) of dirt specks
within the physical area
range of 0.02 to 3.0 mm² reported in parts per million as well as
the number of dirt specks
per square meter of sample. Using the algorithm prescribed in this
test method, the maximum dirt
size is limited to 3.0 mm². Extention to other speck sizes (for
example those greater than 3.0
mm² in physical area), may require changes in equipment,
calculation procedures, or both, and
is not covered in this test method. This test method cannot be used
for physical area measurements
since it does not correctly measure the dirt specks for that mode of
measurement.
The specimen to be evaluated must have a brightness, as determined by
Test Method D 985, of 30 % or
greater. It may be necessary to reform some pulp sheets into
handsheets if the surface is too rough
or textured.
This test method is an instrumental equivalent of Test Method D 2019,
TAPPI T 437, and TAPPI T 213,
all three of which report the equivalent black area of dirt in parts
per million, and TAPPI T 537,
which reports the number of specks of 0.02 mm² or larger per
square meter. This test method
can be implemented using any image analysis system, provided that it
meets the criteria specified
herein.
