Definition of ASTM D1193-91

The user should choose the appropriate sterilization technique for the intended use. TOC is typically measured in parts per billion ppbwith Type 1 water systems having less than 10 ppb.

High TOC measurements can be indicative of bacterial biofilm growth within a water supply or other upstream biological contamination. Copyright Compu-tecture, Inc. Type 1 water quality systems typically have measurements of less than 0.

Note-Because distillation is a process commonly relied upon to produce high purity water, the levels specified for Type II reagent water were selected to represent the minimum quality of water that a distillation process should produce.

With that being said, how is water quality measured and how do researchers determine the purity of water necessary for their process? Researchers should consider astmm analytical tasks and have the recommended water satm on hand. 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. A number in parentheses indicates the year of last reapproval.

TOC is a measurement of the amount of organic carbon that is found in a water sample. Endotoxins are lipopolysaccharide wstm released when bacterial cells die.
