ASSE International considers product performance standards to be of great value in the
6、 development of improved plumbing systems. ASSE standards are developed in the interest of consumer safety. A positive air pressure reduction device for sanitary drainage systems is a device specifically designed to protect water trap seals against unwanted positive pressure transients in sanitary d
7、rainage systems. The ASSE 1030 working group, which developed this standard, was set up within the framework of the ASSE International Product Standards Committee. Recognition is made of the time volunteered by members of the working group and of the support of manufacturers, who also participated i
8、n meetings for this standard. This standard does not imply ASSE Internationals endorsement of a product that conforms to these requirements. Compliance with this standard does not imply acceptance by any code body. It is recommended that these devices be installed consistent with local codes by qual

17、 Sanitary Drainage Systems 1 ASSE Standard #1030-2016 Performance Requirements for Positive Pressure Reduction Devices for Sanitary Drainage Systems Section I 1.0 General 1.1 Application Positive pressure reduction devices (herein referred to as “device”) are to be used in building drainage waste an
18、d vent (DWV) systems. They are intended to reduce the impact of short duration air pressure transients that arise in DWV networks through use. They are not intended to have any effect on long duration or steady-state offsets in air pressure. 1.2 Scope 1.2.1 Description See Figure 1 for a simple arra
19、ngement of components. The device consists of a variable volume reservoir contained within a ventilated rigid outer casing with an inlet connection by which the reservoir inflates when subjected to positive pressure. In its inactive state, the flexible reservoir is deflated. Expansion only occurs in
20、 response to an increase in line pressure at the entrance to the device. This expansion provides a variable volume reservoir for air. The device connects to the drainage network via an airtight seal to prevent the diversion of airflow from entering the reservoir. As a result, the reservoir becomes a
21、n integral part of the drainage network.

22、ments 1.3.1 Temperature The device shall function at temperatures from -40.0 F to 150.0 F (-40.0 C to 65.6 C). 1.3.2 Pressure The device shall remain air tight up to an applied pressure differential of 5.0 psi (34 kPa). 1.3.3 Device Opening Time When subjected to a Standardized Test Positive Pressur
23、e Wave, the device shall open within 10 milliseconds (see Figure 5). The opening time of the device is defined as the time difference between the initial wave identification traveling toward the device on test, and the first subsequent pressure reduction wave arriving at the transducer, as a reflect
24、ion of the opening reservoir volume minus the pipe period of 62.5 msec. These times are determined from the graph of data recorded from Transducer #2. Opening time may be determined from time “A,” 62.5 msec, as shown on Figure 5. (Note that volumes already open due to defective construction will hav
25、e an opening time of zero) 1.3.4 Device Filling Time When subjected to a Standardized Test Positive Pressure Wave, the filling time of the device shall be greater than 25% of the rise time of the applied Standard Test Positive Pressure Wave (see Figure 5). The filling time of the device is defined a
26、s the time from the first reduced peak (opening time) until the device starts to pressurize. This is shown as time “B” on Figure 5. 1.3.5 Connections Connection types must conform to the following standards: Taper Threads: ASTM F1498 for plastic ASTM B1.20.1 for metal Hubless: ASTM C-564, CSA B602 o

34、 for Sanitary Drainage Systems 5 ASSE Standard #1030-2016 Section III 3.0 Performance Requirements and Compliance Testing 3.1 Air Tightness Test 3.1.1 Purpose The purpose of this test is to determine if the device is airtight in order to prevent leakage. 3.1.2 Procedure The device shall be tested at
35、 a controlled temperature of 73.4 F 3.6 F (23.0 C 2.0 C) and at atmospheric pressure. Assemble the device in the test rig, per Figure 2, in accordance with the manufacturers instructions. Open the air inlet valve and uniformly increase the pressure from 0.0 psi to 5.0 psi (0.0 kPa to 34 kPa) over 15
36、 seconds +2/-0 seconds. Close the air inlet valve. After 5 minutes, record the internal pressure of the device. 3.1.3 Criteria Any internal pressure loss greater than 0.25 psig (1.72 kPa) over the 5 minute period shall result in rejection of the device. 3.2 Rating Test 3.2.1 Purpose The purpose of t
37、his test is to determine the capacity of the device. 3.2.2 Procedure The device shall be tested at a controlled temperature of 73.4 F 3.6 F (23.0 C 2.0 C) and at atmospheric pressure. Fill the bladder of the device with water until it reaches its full capacity. Pour out the water, measure and record
38、 the capacity (volume) as Vol U . 3.2.3 Criteria A capacity (Vol u ) of less than 4.2 US quarts (4.0 liters) shall result in a rejection of the device. 3.3 Endurance Test 3.3.1 Purpose The purpose of this test is to determine if the device sustains any damage, permanent deformation or impairment of
39、operation as a result of cycling at extremes of temperature. 3.3.2 Procedure High Temperature Devices shall be placed in an environment where the temperature is maintained at 150 F (65.6 C) for a period of 8 hours. After 8 hours, remove the device and immediately install the device on the test assem
40、bly, as shown in Figure 2. After the device is installed, subject the device to a pressure of 2.0 psi (13.8 kPa) for 50,000 cycles at a fill rate of 15 2 cycles per minute. During the cycle test, the device shall return to the laboratory controlled temperature of 73.4 F 3.6 F (23.0 C 2.0 C). Upon co
41、mpletion of this test, the device shall be tested as prescribed in the Air Tightness Test in Section 3.1.6 Positive Pressure Reduction Devices for Sanitary Drainage Systems ASSE Standard #1030-2016 Figure 2 Device on Test 4” (100 mm) Pipe Pressure and Timing Device Connection Pressure Gauge 3.3.3 Pr
42、ocedure Low Temperature Upon completion of the high temperature test in Section 3.3.2 of this standard, place the same device in an environment where the temperature is maintained at -40.0 F (-40.0 C). After 8 hours, remove the device and immediately install the device on the test assembly, as shown
43、 in Figure 2. After the device is installed, immediately subject the device to a pressure of 2.0 psi (13.8 kPa) for 50,000 cycles at a rate of 15 2 cycles per minute at a laboratory controlled temperature of 73.4 F 3.6 F (23.0 C 2.0 C). Upon completion of this test, the device shall be tested as pre
44、scribed in the Air Tightness Test in Section 3.1. 3.3.4 Criteria Failure to meet the criteria of Section 3.1.3 following the endurance tests shall result in a rejection of the device. 3.4 Test Fixture Description, Calculations and Setup All timings are quoted in milliseconds (msec). Pressure is quot
45、ed in Pascals (Pa) and inches of water column (in), where 1.0 in (25.4 mm) of water equals 0.25 kPa (0.036 psi). The pressure data (inches of water column, vertical axis) recorded from Transducer #1 and #2 are recorded and plotted over time (msec, horizontal). Horizontal and vertical scales should b
46、e the same for both graphs. The characteristics of the Standardized Test Positive Pressure Wave are shown in Figure 4. The test fixture consists of a wave generator (controllable piston), which “fires” a pressure wave down the pipe that is terminated by the device on test. Two transducers, at specif
47、ied locations along the length of pipe, measure the characteristics of the Standardized T est Positive Pressure Wave and the performance of the device on test. Transducer #1 provides the data necessary for “tuning” the Standardized Test Positive Pressure Wave before the actual test. To tune the wave
48、 generator, the stroke speed of the piston is adjusted so that the Standardized T est Positive Pressure Wave has a peak pressure of 4.0in of water column (1.0 kPa). Then, during the actual test, Transducer #2 measures the resulting wave as it is reflected. The data is recorded and plotted. Positive
49、Pressure Reduction Devices for Sanitary Drainage Systems 7 ASSE Standard #1030-2016 3.4.1 Wave Generator Sizing For the purposes of this test, the volume of air displaced (Vol a ) by the piston is designed to be greater than the working volume (Vol u ) of the device (Vol a= Vol ux 1.1) so that the inflated reservoir becomes pressurized and generates a positive reflected wave, allowing the measurement of filling time. If a device had a volume greater than the volume of air displaced by the piston, then the filling time
