Phạm vi áp dụng / Scope of standard

This standard practice covers the process of drying compacted
field and laboratory specimens using a vacuum apparatus. The values
stated in SI units are to be regarded as the stand.

The specimens dried by this practice remain at close to room
temperature, which helps in maintaining specimen integrity during
the drying process and allows the operators to run repeated tests
on the same sample, if necessary.

This standard can also be used for drying other construction
materials such as concrete, soils, aggregates, and loose asphalt
mixtures. Use recommendations provided from the manufacturer for
drying other construction materials.

This standard practice may involve hazardous materials,
operations, and equipment. 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.
