4. If the water in the hole disappears within 10 minutes, you can complete the infiltration test immediately. If water is still present in the hole at the end of 10 minutes, leave the water in the hole overnight and return the next day. 5. The next day, refill the hole with water and record the time. 6.
The C.B.R. value usually is selected at 2.5 mm penetration. If the C.B.R. at 5 mm is greater than at 2.5 mm, the test should be repeated. If the check test results are similar, then the value for 5 mm penetration is used as. Generally, the CBR test is conducted for three test specimens and the average value is taken of the three.
The other problem is that blower door results don't really correlate to "ACH(nat)" rates. ACH(nat) will always be a guess or an estimate, because a blower door doesn't tell you where the holes are. A hole in the basement or attic has a much greater effect on infiltration than a hole near the neutral pressure plane.
Theoretical examples: model setup - Results and discussion. 22.214.171.124 Test problem 1: constant infiltration in HYDRUS-1D. A one-dimensional test example called “Skaggs´ column infiltration test”, distributed with HYDRUS-1D, is used as the basis for a first validation of the implementation of the scaling factor.
The mobile infiltration test unit (MITU), a 12 sq m construction-site office trailer modified to provide long-term field data for air infiltration studies, is described. The trailer and its instrumentation, including some preliminary tests of the individual measurement systems, are discussed. It has a completely automated data acquisition system that records air infiltration rates, surfaces ...
For the interpretation of the test result the following scheme can be used: IR Irritant reaction. - Discrete patchy erythema without infiltration. +++ Extreme positive reaction. - Coalescing vesicles. - Bullous or ulcerative reaction. ++ Strong positive reaction. - Erythema - Infiltration. - Papules - Discrete vesicles.
The lidocaine infiltration test is an useful test to predict the results of styloidectomy for Eagle's syndrome. Free full text Indian J Otolaryngol Head Neck Surg . 2013 Jan; 65(1): 20-23.

over-estimate infiltration rates for facilities underlain by low-permeability layers or strata. For example, according to equation 3 on page 140, a facility with a ponded water level of 2 feet, a low-permeability layer at a depth of 15 feet, and the water table at 30 feet would result in greater infiltration than the same facility without this ...
4.0 RESULTS Infiltration rates increased substantially after cleaning of the pavement based on all test results. Table 2 provides a summary of each test at each site location. The infiltration testing prior to cleaning resulted in low infiltration rates.
starting test pressure of 3.5 psi gage, commence the test. Before starting the test, the pressure may be allowed to drop to 3.5 psig. Record the drop in pressure for the test period. If the pressure has dropped more than 1.0 psi gage during the test period, the line shall be presumed to have failed. The test may be discontinued
5.1 This test method is useful for field measurement of the infiltration rate of soils. Infiltration rates have application to such studies as liquid waste disposal, evaluation of potential septic-tank disposal fields, leaching and drainage efficiencies, irrigation requirements, water spreading and recharge, and canal or reservoir leakage, among other applications.
