30、WITHOUT PERMISSION FROM UL 7 Efficiency and Resistance Tests 7.1 General 7.1.1 When tested as described in 7.1.2 7.2.1, the efficiency of a lter unit shall be not less than 99.97 percent (the maximum penetration through the lter shall be not more than 0.03 percent of the particles introduced in the
31、air upstream of the test sample) and the resistance (pressure differential) across the lter unit at the specied air ow rate shall be not more than 1.3 inch water column (324 Pa) for units rated 25, 50, 125, 1500, and 2000 cfm. For units rated 500 and 1000 cfm, the resistance shall not be more than 1
32、.0 inch water column (249 Pa). 7.1.2 Samples of the lter unit are to be tested by the manufacturer in accordance with the Test Method in Section FC of the ASME AG-1, Code on Nuclear and Gas Treatment. For this test, a “penetrometer” is to be used. 7.1.3 In the penetrometer, air of controlled tempera
33、ture and humidity is to be circulated through a heated container of liquid Emery 3004 or a suitable alternative at a rate controlled to produce a constant number of uniform aerosol particles, 0.3 micron in diameter, per unit volume. The resultant aerosol is to be blown through the lter unit under te
34、st and the density of the aerosol downstream of the lter is to be measured by a light beam-photocell combination. A comparison of the downstream density readings with the known aerosol density upstream of the lter unit then is to serve as the basis for calculating the efficiency of the lter unit. 7.
35、1.4 During the test, the air ow through the lter unit is to be maintained at the manufacturers air-ow rating. 7.2 Conrmation of results 7.2.1 As a conrmation of results of tests by the manufacturer, three samples from each line of lter units having similar design and construction are to be tested at
36、 Air Techniques International, 1708 Whitehead Road, Suite 104, Baltimore, Maryland for compliance with the requirements in 7.1.1: 8 Penetration Tests 8.1 Samples 8.1.1 Samples selected for testing are to be representative of other sizes of similar design and construction. 8.1.2 Initially, six sample
37、s are to be tested in the as-received condition for percent of aerosol penetration as specied in 8.3.1 and 8.3.2. Of these six samples, three then are to be subjected to the heated air test described in 8.4.1 8.4.3, one to the moist air test described in 8.5.1 8.5.3, one to the low temperature test
38、described in 8.6.1 8.6.3, and one to the Spot Flame Test, Section 9.

39、lame Test, Section 9, are to be conducted in a horizontal duct 27 by 27 inches (686 by 686 mm) in cross section and 13-1/2 feet (4.12 m) long. The duct is to be made of stainless steel reinforced with angle iron. One end of the duct is to be tapered and attached to the discharge of a constant-speed
40、blower that, in turn, has an adjustable air-intake opening preceded by a calibrated venturi or similar ow meter. 8.2.2 Instrumentation for measuring the resistance (pressure differential across the test specimen) and air temperature is to be provided. 8.2.3 A portable air-operated generator for prod
41、ucing an aerosol of Emery 3004, or a suitable alternative, a forward light-scattering cell, and a percent penetration indicator are to be provided for making percent penetration determinations. 8.2.4 This generator is to consist of an unheated container of liquid Emery 3004, or a suitable alternativ
42、e and a set of aspirator nozzles connected to a building service air line. 8.2.5 The discharge end of the duct is to be unobstructed for all tests except the aerosol penetration test described in 8.3.2. For this test, an adapter and a exible 18-inch (457-mm) diameter, 25-foot (7.62-m) long duct are
43、to be provided to produce a uniform mixture of air and aerosol particles at the duct exit. 8.2.6 A metal frame is to be provided at the center of the duct to receive the lter unit. The duct is to be provided with tight-tting doors and windows to permit lter units to be mounted and observed during th
44、e test. 8.2.7 The upstream section of the duct is to be equipped with facilities for heating the air to be passed through the lter unit as required for the heated air test described in 8.4.2. 8.2.8 The size of the constant-speed blower and the design of the adjustable air intake are to permit delive
45、ry of the required ow of air. 8.2.9 Equipment is to be provided for conditioning test samples in atmospheres of 50 5 and 90 5 percent relative humidity at 77F (25C) and at normal atmospheric pressure, and for reducing the temperature of test samples to 27 4F (minus 3 2C).

47、. 8.3.2 Each sample is to be mounted in the test duct and the air ow is to be adjusted to the manufacturers air-ow rating. The aerosol portable generator a is to be used to introduce aerosol particles into the inlet of the calibrated venturi ow meter. The aerosol penetration is to be measured downst
48、ream of the unit by means of the forward light-scattering cell and percent penetration indicator. The test is to be conducted at room temperature 70 10F (25 6C). a It should be recognized that the percent aerosol penetration value obtained when using this aerosol portable generator is generally lowe
49、r than that determined at the factory when using the hot aerosol machine. 8.4 Heated air test 8.4.1 When tested as specied in 8.4.2 and 8.4.3, the percent aerosol penetration through a lter unit shall be not more than 3.0. 8.4.2 Each sample (see 8.1.2) is to be installed in the test duct and subjected to the ow of heated air for 5 minutes. The temperature of the heated air is to be 700 50F (371 27C), as measured at each of six points
