Standard Method of Test for
Determination of Moisture in Soils by
Means of a Calcium Carbide Gas Pressure Moisture Tester
AASHTO Designation: T 217 -02 (2006)
SCOPE
1.1.This method of test is intended to determine the moisture content of soils by means of a calcium carbide gas pressure moisture tester.
The manufacturer’s instructions shall be followed for the proper use of the equipment.
1.2.The following applies to all specified limits in this standard:
For the purposes of determining conformance with these specifications, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last
right-hand place of figures used in expressing the limiting value, in accordance with ASTM E 29.
Note 1-This method shall not be used on granular materials having particles large enough to affect the accuracy of the test-in general any appreciable amount
retained on a 4.75-mm sieve.
The super 200 D tester is intended to be used to test aggregate.
1.3.The values stated in SI units are to be regarded as the standard.
1.4.Refer to R 16 for regulatory information for chemicals.
