The incremental amount of suitable fluid added can be adjusted down as needed for carriers with LHC less than 5.08201;%. 3.2 This test method has been designed principally for granular carriers with a relatively rapid absorption of liquid. Some materials may absorb liquids more slowly than the described times in the method. If such is the case, the time limit of two (2) min. may be extended. 3.3 This test method is applicable to granules in the range from 4 to 100 mesh (4.75 to 0.150 mm). 1.1 This test method is used to determine the liquid holding capacity (LHC) of granular carriers. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. For specific precautionary statements, see Section 5.

GSO ISO 11461:2013 土壤质量 使用钻套以分数体积估算土壤含水量 体积法

This International Standard specifies a method for the gravimetric determination of soil water content as a volume fraction. The method is applicable to all types of non-swelling or non-shrinking soils where coring sleeves can be used for sampling. It is not applicable to soils where stones, tough roots or other factors prevent collection of soil cores. It is used as a reference method (e.g. the calibration of indirect methods for determination of water content). NOTE The determination of water content as a mass fraction is described in ISO 11465.

This International Standard gives a simplified theory of the physics of soil water in the unsaturated zone and defines a set of terms, quantities, units and symbols used in the field of soil physics investigation of the unsaturated zone. This International Standard is applicable only to standards on soil physical investigations of the unsaturated zone (including swelling soils) elaborated within ISO/TC 190. This International Standard specifically excludes macropore flow.

GSO ISO 17312:2013 土壤质量 使用实心壁渗透计估算饱和多孔材料的水力传导率

This International Standard specifies the determination of the hydraulic conductivity of granular soils (e.g. sand and gravel) using a constant-head method involving a rigid-wall permeameter to measure the laminar flow of water. The procedure establishes representative values of the hydraulic conductivity of granular soils that can occur in natural deposits as placed in embankments, or when used as base courses under pavements. In order to limit consolidation influences during testing, this procedure is applicable only to disturbed granular soils containing not more than 10 % soil passing a 75-μm sieve. This procedure is applicable to the measurement of hydraulic conductivity of compacted samples of sands and gravels containing little or no silt, where flow along the rigid wall of the permeameter has no practical implications on the test results. This International Standard is not applicable to silt and clay, where seepage/flow at the boundaries is not acceptable.

GSO ISO 10573:2013 土壤质量 非饱和带含水量估算 中子测深法

This International Standard specifies an in situ method for the determination of water content in the unsaturated zone of soils using a neutron depth probe. lt is applicable when investigations into the water storage, water balance and water distribution in the unsaturated zone of the soil are carried out. Because the method is non-destructive, it is particularly suitable for repeated measurements at fixed locations. Water content profiles tan be obtained by measuring at a series of depths down to any depth within the range of the phreatic level at the site. The advantage of the method compared with some others, for example the gamma probe method, is the rapidity with which measurements tan be carried out. A disadvantage, however, is the relatively poor depth resolution of the measurements.

GSO ISO 11276:2013 土壤质量 水压测深估算 表面张力测量方法

This International Standard specifies methods for the determination of pore water pressure in both unsaturated and saturated soil using tensiometers. The methods are applicable for in situ pore water pressure measurements in the field, as well as for monitoring pore water pressure in, for example, plant Containers or soil cores used in experimental procedures. At normal atmospheric pressures, i.e. about 100 kPa, the application of these methods is limited to a range of pressures down to about - 85 kPa. The range is reduced at lower atmospheric pressures. Tensiometers will not function if sub-zero temperatures occur at the measurement depth. Their accuracy is influenced by seil and air temperature fluctuations. Tensiometer response time ranges from a few seconds to several days. To obtain reliable measurements under field conditions, tensiometers require frequent servicing. A tensiometer provides Point measurements of pore water pressure. To measure pore water pressure at different depths, several tensiometers will be necessary. In the field, replicate sets of instruments will be required if the spatial variability of the soil is to be allowed for
