METHOD 5B -
DETERMINATION OF NONSULFURIC ACID PARTICULATE MATTER EMISSIONS FROM STATIONARY
SOURCES
NOTE: This method does not include all of the
specifications (e.g.,
equipment and supplies) and procedures (e.g., sampling and analytical) essential to its
performance. Some material is incorporated by reference from other methods in
this part. Therefore, to obtain reliable results, persons using this method
should have a thorough knowledge of at least the following additional test
methods: Method 1, Method 2,
Method 3, Method 5.

1.1 Analyte.
Nonsulfuric acid particulate matter. No CAS number assigned.
1.2 Applicability.
This method is determining applicable for the determination of nonsulfuric acid
particulate matter from stationary sources, only where specified by an
applicable subpart of the regulations or where approved by the Administrator
for a particular
application.
1.3 Data Quality
Objectives. Adherence to the requirements of this method will enhance the
quality of the data obtained from air pollutant sampling methods.
Particulate matter is
withdrawn isokinetically from the source and collected on a glass fiber filter
maintained at a temperature of 160 ± 14 ¡C (320 ± 25 ¡F). The collected sample
is then heated in an oven at 160 ¡C (320 ¡F) for 6 hours to volatilize any
condensed sulfuric acid that may have been collected, and the nonsulfuric acid
particulate mass is determined gravimetrically.
5.1 Disclaimer. This
method may involve hazardous materials, operations, and equipment. This test
method may not address all of the safety problems associated with its use. It
is the responsibility of the user of this test method to establish appropriate
safety and health practices and to determine the applicability of regulatory
limitations prior to performing this test method.
Same as Method 5, Section 6.0, with the following
addition and exceptions:
The probe liner
heating system and filter heating system must be capable of maintaining a
sample gas temperature of 160 ± 14 ¡C (320 ± 25 ¡F).
An oven is required
for drying the sample.
Same as Method 5, Section 7.0.
Same as Method 5,
with the exception of the following:
Oven dry the filter
at 160 ± 5 ¡C (320 ± 10 ¡F) for 2 to 3 hours, cool in a desiccator for 2 hours,
and weigh. Desiccate to constant weight to obtain the initial tare weight. Use
the applicable specifications and techniques of Section
8.1.3 of Method 5 for this determination.
Maintain the probe
outlet and filter temperatures at 160 ± 14 ¡C (320 ± 25 ¡F).
Same as Method 5, Section 9.0.
Same as Method 5, Section 10.0.
Same as Method 5, Section 11.0, except replace Section
11.2.2 with the following:
11.1 Container No. 2.
Note the level of liquid in the container, and confirm on the analysis sheet
whether leakage occurred during transport. If a noticeable amount of leakage
has occurred, either void the sample or use methods, subject to the approval of
the Administrator, to correct the final results. Measure the liquid in this
container either volumetrically to ± 1 ml or gravimetrically to ± 0.5 g.
Transfer the contents to a tared 250 ml beaker, and evaporate to dryness at
ambient temperature and pressure.
Then oven dry the probe and filter samples at a temperature of 160 ± 5
¡C (320 ± 10 ¡F) for 6 hours. Cool in a desiccator for 2 hours, and weigh to
constant weight. Report the results to the nearest 0.1 mg.
Same as in Method 5, Section 12.0.
Same as Method 5, Section 17.0.
