METHODS OF SAMPLING AND TEST PHYSICAL AND CHEMICAL FOR WATER AND WASTE WATER PART 17 NON-FILTERABLE RESIDUE TOTAL SUSPENDED SOLIDS at 103 —— C-105 —— C Second Revision

This standard provides detailed procedures for the sampling and testing of physical and chemical parameters in water and wastewater. It specifically addresses the determination of total suspended solids under conditions of heating at temperatures between 103 °C and 105 °C. The method outlines the steps for collecting samples, preparing them for analysis, and conducting the necessary tests to ensure accurate results. It includes guidelines for handling and storing samples to maintain their integrity throughout the process. The standard also specifies the equipment required and the conditions under which the tests should be performed. The procedures are designed to ensure consistency and reliability in the measurement of total suspended solids in water and wastewater samples.
