Weight Gain – Loading Dust Weight Gain (weight gain):
The total of the loading dust weight gains for all dust increments performed during a
complete ASHRAE 52.2-1999 test. The synthetic dust weight gain for each dust increment
is determined as the weight of the dust fed (as specified in section 10.7.2.2 of ASHRAE
52.2-1999 minus the weight of the synthetic dust passing the air cleaning device, as
determined in accordance with sections 11.3.2 through 11.3.14 of ASHARE 52.1-1992.
Objective:
Determine the ASHRAE loading dusting weight gain of an air filter, by defining
additional test procedures and observations to be made during a 52.2 test.
Constraint:
None of the additional procedures may conflict with the requirements of 52.2. The test
must be a complete test in accordance with 52.2, with additional procedures and
observations reported.
Procedure:
Perform the Test Program for Dust Loading and Particle Size Efficiency in accordance
with section 10.7 of 52.2, with the following additional steps described below. Establish
the test parameters and dust increments according to section 10.7.1 of 52.2.
For each dust increment:
1. Weight the final filter to the nearest 0.1 gram (52.1 : 11.2.1)
2. Proceed with the Dust Loading procedure as specified in 10.7.2.1 through 10.7.2.8 of
52.2. While performing step 10.7.2.6 of 52.2, also brush dust remaining in the feeder
tray into the aspirator, as required in section 11.3.7 of 52.1.
3. Stop the air flow and remove the final filter in accordance with 10.7.2.9 of 52.1,
also collecting and weighing the test dust remaining in the duct, as specified in section
11.3.12 and 11.3.13 of 52.1.
4. Add the weight of the dust collected between the test device and the final filter to the
weight increase of the final filter to establish the amount of synthetic dust passing the
device during the feed period, as specified in 11.3.14 of 52.1.
5. Calculate the weight gain for the increment as the weight of the dust fed minus the sum
of the weight increase of the final filter and the weight of dust collected between the
device and the final filter.
Calculate the weight gain of the filter as the sum of the weight gains for all of the dust
increments.

their filter is out of compliance and the use of the NAFA Product Certification Symbol will
be suspended. Suspended means they can not obtain a NAFA Product Certification
Certificate until the product is back into compliance.
14.5
Within 45 calendar days, the Participant, the NAFA Product Certification Administrative
Agency and the NAFA Testing Laboratory will work to correct the deficiency and a third
filter will be randomly tested. A procurement and testing fee will be assessed for this
service.
14.6
If the third filter fails to pass the test, the Participant will be notified by the NAFA Product
Administrative Agency and the license to use the NAFA Certification Symbol will be
revoked. The NAFA Product Certification Administrative Board will receive notification.
The filter registration will be shown as delisted on the NAFA Website for a period of 6
months or until the filter is reclassified. The NAFA Product Certification Symbol must be
removed from the product (or physically marked out on the product). Distribution of any

Testing of Types (Models) of Filters
15.1
Panel Filters:
To obtain NAFA Product Certification a flat panel filter commonly referred to as fiberglass
panels, are tested at the manufacturers advertised velocity (normally 300 fpm for a 1”
panel). Polyester panels shall be tested at ASHRAE 52.2 velocities or the manufacturer’s
listed upper limit velocity, whichever is higher. NAFA Product Certification of filters will
be listed by manufacturers’ model reference. (For example, a fiberglass panel with a
certain style of backing will allow the NAFA Product Symbol to be placed on all fiberglass
panels with that style of backing of exactly the same Model Number and construction and
fabrication – size being the only difference). Other filter sizes may be evaluated using the
same calculated media/velocity ratio.
15.2
Pleats:
To obtain NAFA Product Certification a pleated panel filter shall be tested at a velocity
listed in the NAFA Guide to Air Filtration, page 4.7 or the manufacturers advertised upper
limit velocity, whichever is greater. NAFA Product Certification of filters will be listed by
manufacturers’ model reference. (For example, testing of a high capacity pleat will allow
the NAFA Product Certification Symbol to be placed on all high capacity pleats of exactly
the same Model Number and construction and fabrication – size being the only difference).
Other filter sizes may be evaluated using the same corresponding media/velocity ratio.
15.3
Extended Surface Filters:
To obtain NAFA Product Certification an extended surface (pocket or bag filter) shall be
tested at the velocity listed in the NAFA Guide to Air Filtration, page 4.7 or the
manufacturers advertised upper limit velocity, whichever is greater. (For example, testing
of an extended surface filter will allow the NAFA Product Certification Symbol to be
placed on all extended surface filters of exactly the same Model Number and construction
Page Number 11

15.4
ASHRAE Box-type Filters:
To obtain NAFA Product Certification an ASHRAE box-type filter shall be tested at the
velocity listed in the NAFA Guide to Air Filtration, page 4.7 or the manufacturers
advertised upper limit velocity, whichever is greater. (For example, testing of an ASHRAE
box-type filter will allow the NAFA Product Certification Symbol to be placed on all
extended surface filters of exactly the same Model Number and construction and
fabrication – size being the only difference). Other filter sizes may be evaluated using the
same corresponding media/velocity ratio.
15.5
Other Filter Types:
15.5.1 To obtain NAFA Product Certification, “Other” style filters shall be tested at the velocity
listed in the NAFA Guide to Air Filtration, page 4.7 or the manufacturers advertised upper
limit velocity, whichever is greater. Certification of one style of “other” types of filters
may not necessarily allow the NAFA Product Certification Symbol to be placed on “other”
products of the same construction and fabrication – size being the only difference. See
14.6.
15.6
Any Participant receiving license to use the NAFA Product Certification Symbol must
have the review and approval of the NAFA Product Certification Administrative Board.
