Mariotte Tubes Instructions
IN12-W Mariotte Tubes
Outline of Instructions for using IN10-W and IN14-W
with Mariotte Tubes (Read First)
Installation of Tubes:
To prevent the Mariotte Tubes from gravitationally forcing water into the rings, be sure they
are installed at a proper level in relation to the Turf-Tec Infiltration rings.
Each Mariotte tube comes with a calibrated sight glass located on the side. When setting
up the test, use the Mariotte tube height to regulate the amount of water that fills up the
inner and outer ring until a constant flow is achieved. This is described in section 8.6.3
through 8.6.12 and Figure 2 located on page 9 and Figure 4 on page 13. If the top valve is
open and you are using the Mariotte Tubes as a graduated cylinder, the bottom valve can
also be opened to different positions to allow more or less water to flow into the Turf-Tec
Infiltration rings.
Maintenance of Mariotte Tubes:
Mariotte tubes should be cleaned out with a 5% bleach and 95% water solution before
storing.
Source of subsequent instructions:
Many portions of the following instructions are from the ASTM Publication
Designation: D-3385-03, from the Annual Book of ASTM Standards. To view it in its
entirety, a full copy of the standards should be purchased at www.astm.org. Note the
6 and 12 inch infiltration rings do not comply with ASTM D-3385-03. Only the IN10-W
and IN14-W (12 and 24 inch) rings comply with the ASTM D-3385-03.
1. Scope
1.1 This test method describes a procedure for field measurement of the rate of infiltration
of liquid (typically water) into soils using double-ring Infiltrometer.
1.2 This standard does not purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability of regulatory limitations
prior to use.
