Table 1. Breakdown of numbers and titles of standards elaborated by TC190/SC 5 “Physical methods” ISO 10573:1995 ISO 11272:1998 ISO 11274:1998 ISO 11276:1995 ISO 11277:1998 ISO 11277:1998/Cor1:2002 ISO 11461:2001 ISO 11508:1998 ISO 16586:2003 Soil quality - Determination of water content in the unsaturated zone - Neutron depth probe method Soil quality - Determination of dry bulk density Soil quality - Determination of the water-retention characteristic - Laboratory methods Soil quality - Determination of pore water pressure - Tensiometer method Soil quality - Determination of particle size distribution in mineral soil material - Method by sieving and sedimentation Soil quality - Determination of soil water content as a volume fraction using coring sleeves - Gravimetric method Soil quality - Determination of particle density Soil quality - Determination of soil water content as a volume fraction on the basis of known dry bulk density - Gravimetric method Before the international standard is finally accepted by ISO, the procedure of standards elaboration provides several intermediate stages. Particular projects of a given standard, which are the effect of the work performed in a stage, are accordingly denoted at the standard’s number. For instance: - ISO/CD denotes Committee Draft and is the result of work done in a working group. This is the first proposition to formulate this problem in the form of a standard. A possibility exists to publish several CDs. - ISO/DIS denotes Draft International Standard and is the effect of consultation and discussion, which took place outside the working group. - ISO/FDIS denotes Final Draft International Standard and is the last version of the document, proceeding an official publication. One of working groups - SC SC5, in the second half of the 90-ies, led to publishing ISO/CD 12229 „Soil Quality – Determination of soiling water content volume fraction – Time Domain Reflectometry (TDR) and Time Domain Transmissometry (TDT) Methods”. The procedure of standard’s elaboration is a little bit arduous and prolonged in time. It requires that the experts from various countries were engaged in the working group. Therefore, particular persons can resign of different motives from 32
participation in a working group and the quorum is not preserved. In such case the work on a given standard are suspended. Such situation took place in case of the standard ISO/CD 12229. The decision of ISO/TC 190/SC 5 WG 3 “Water content” from 7/11/2000, suspended the work on further elaboration of the standard. Taking into consideration that the normalization of the soil water content measurement with application of TDR technology is really needed by the users, the Institute of Agrophysics PAS in <strong>Lublin</strong> in the frame of the Center of Excellence “Agrophysics” has made a trial to reactivate the works on that standard. To strengthen our efforts we would like to prompt the participants of this conference to support this work. This support can consist in making the national standardization committees in particular countries interested in joining this issue. 33
