Sets out a gravimetric method for the determination of total, fixed and volatile dissolved and suspended solids in water. The method is applicable to potable waste and saline waters at concentrations up to 40 g/L.
Scope
This Standard sets out methods for the gravimetric determination of total, fixed, volatile dissolved and suspended solids in waters. These methods are directly applicable to potable, waste and saline waters having concentrations of dissolved and suspended solids up to 40 000 mg/L. Dilution of the filtered sample may be used to extend the limit for dissolved solids. This method may underestimate the amount of suspended solids if their nature alters during the procedure, due to solubility, colloidal stability or changes in physical integrity.
NOTES:
1 A method for the determination of suspended solids in samples which are difficult to filter is given in Appendix A.
2 The determination of low concentrations of volatile solids in the presence of high concentrations of fixed solids may be subject to considerable error.
