Common use of Method of testing Clause in Contracts

Method of testing. Chemical composition testing for sodium chloride shall conform to the rapid method of testing given in Appendix A1 of AASHTO M-143-86. A second method of rapid analysis could be the use of Gran’s plot titration method developed by Orion Research Incorporated. In case that the coarse salt sample is used 100.00 g sample is taken and dissolved in a 2-liter volumetric flask quantitatively. An aliquot of 5.00 ml or 2.00 ml of this solution is then pipetted out to the titrated according to either of these two methods. If controversy occurs, analysis shall be made in accordance with the method specified for “Salt” in the current “Official Methods of Analysis for the Association of Official Agricultural Chemists”.
