Adaptations and Additions to ASTM Test Method E 514 (Water Permeance of Masonry) for Field Conditions

Source

The main proposed adaptation of ASTM Test for Water Permeance of Masonry (E 514) concerns the exploration of field conditions. Emphasis is placed primarily on the measurement of water passing into the exterior face of a masonry wall, rather than measurement of conditions from water passing through to the inside face. A tentative rating criterion for water penetrating the exterior face is suggested. This measurement is useful to evaluate the effectiveness of water-repellent treatments on the surface and to assess the water that stays in the wall, possibly never penetrating to the interior face.

The main proposed addition to ASTM E 514 is a calibrated nozzle technique used to test permeance at caulkings, flashings, expansion joints, gravel stops, etc., not easily tested by the enclosed chamber method of E 514. Such an auxiliary device can be calibrated and applied to simulate desired rainfall intensity and wind pressure.
