Test atthe maximum thickness supplied.12.7 Erosion Resistance Test:12.7.1 ScopeThis method covers the evaluation of fibrousglass duct lining insulation for damage and progressive erosiondue to contact with a moving air stream.12.7.2 Significance and UseThis method provides a r
36、ela-tively simple and short term evaluation of in-use performanceutilizing a multiplier (safety factor) of at least 2.56 5 % timesthe rated maximum velocity of the material to account forvariations in installation and for long term effects.12.7.2.1 Initial blow-out of construction debris is specifi-
37、cally excluded from the evaluation.12.7.3 ProcedureFor material intended for rectangularduct, install a sample of 1-in. (25-mm) thick insulation in a 12by 12-in. (305 by 305-mm) sheet metal duct in an L-shapedassembly. For material intended for circular duct, install asample of 1-in. (25-mm) thick i
38、nsulation in a 14-in. (356-mm)diameter metal duct in an L-shaped assembly. The length of theupstream and downstream legs of the assembly shall bebetween 6 and 9 ft (1.8 m and 2.7 m). The 90 bend shall bemade with an elbow as employed for installation. Because theinstallation details will affect the
39、test results, the installationshall be in accordance with the NAIMA Fibrous Glass DuctLiner Standard or SMACNA HVAC Duct Construction Stan-dards. Connect the assembly to a fan by means of a transfor-mation piece to provide for uniform air entry to the testspecimen. The fan must be able to generate t
40、he required testvelocities.12.7.3.1 The air velocity for purposes of the test is to bemeasured by a pitot tube and draft gage, or direct readingvelometer, positioned in the center of the outlet end of thesample. Room air handled by the fan ranging in temperaturebetween 40F (4C) and 100F (38C), shall
41、 be employed.12.7.3.2 The inlet of the fan used for the test shall becovered with a double layer of cheesecloth (14 to 15 squareyards per pound (26 to 28 m2/kg) and known to the trade as“count of 32 by 24”).12.7.3.3 A damper, if employed for regulating velocity inthe duct system, is to be located ah
42、ead of the test section.12.7.3.4 For a collecting screen, use a double layer ofcheesecloth (the same type of cheesecloth as specified for thefan inlet) stretched taut on a frame sized to provide for an areanot less than five times the inside cross-sectional area of thetest section.12.7.3.5 The test
43、sample shall not be exposed to a relativehumidity greater than 70 % for 24 h prior to the test.12.7.3.6 The air velocity for the test is dependent upon theuse of the product. For this procedure the test velocity shall bebased on the manufacturers rated velocity for the product. Thetest air velocity
44、is 2.5 6 5 % times the product rated maximumuse velocity.12.7.3.7 Before installing the collecting screen, pass airthrough the lined test section at the test velocity for 1 h.12.7.3.8 Then install the collecting screen 12 in. (305 mm)from the outlet end of the test section.12.7.3.9 The test then is
45、to proceed at test velocity and tocontinue for a period of 4 h. Examine the collecting screen formacroscopic particles at the end of each hour during the testperiod by taping the screen with the adhesive side of transpar-ent tape, or tapes, in order to remove and record any erodedparticles. At the e
46、nd of the test period, there is to be noevidence of continued erosion, and interior surfaces of thesample shall not show evidence of cracking, flaking, peeling,TABLE 2 Sound Absorption Coefficients (min) Using a Type “A”MountingNOTE 1This data is based on round-robin tests.
