Water quality. Guidelines for the determination of total organic carbon (TOC) and dissolved organic carbon (DOC).

This International Standard gives guidance for the determination of total carbon (TC), total inorganic carbon (TIC) andtotal organic carbon (TOC) in drinking water, ground water, surface water, sea water and waste water. It also definesterms and specifies interferences, reagents, and sample pretreatment for water samples.The method described in this International Standard applies to water samples containing organic carbon contentranging from 0,3 mg/l to 1000 mg/l. The lower limit concentration is only applicable in special cases, for exampledrinking water, measured by highly sensitive instruments. Higher concentrations may be determined after appropriatedilution.This International Standard does not deal with the instrument-dependent specifications.Purgeable organic substances, such as benzene, toluene, cyclohexane and chloroform, can also be determined usingthis method.Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined togetherwith the organic carbon.

Sumary

Water quality. Guidelines for the determination of total organic carbon (TOC) and dissolved organic carbon (DOC).

This International Standard gives guidance for the determination of total carbon (TC), total inorganic carbon (TIC) and

total organic carbon (TOC) in drinking water, ground water, surface water, sea water and waste water. It also defines

terms and specifies interferences, reagents, and sample pretreatment for water samples.

The method described in this International Standard applies to water samples containing organic carbon content

ranging from 0,3 mg/l to 1000 mg/l. The lower limit concentration is only applicable in special cases, for example

drinking water, measured by highly sensitive instruments. Higher concentrations may be determined after appropriate

dilution.

This International Standard does not deal with the instrument-dependent specifications.

Purgeable organic substances, such as benzene, toluene, cyclohexane and chloroform, can also be determined using

this method.

Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined together

with the organic carbon.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
