Описание (английский):

Specifies a method for the titrimetric determination of carbonate alkalinity in natural and drinking water. The method is intended for samples with a carbonate alkalinity between 0,01 mmol/l and 4 mmol/l. For samples containing higher concentrations of alkalinity, a smaller test portion can be used for analysis.

Overview

SIST EN ISO 9963-2:1998 specifies a standardized method for the determination of carbonate alkalinity in natural and drinking water using titrimetric analysis. Issued by CEN and mirroring ISO 9963-2:1994, this international standard outlines procedures for measuring carbonate alkalinity within the range of 0.01 mmol/l to 4 mmol/l. When water samples contain higher alkaline concentrations, smaller test portions may be utilized for accurate analysis.

The method primarily ensures reliable measurement of water alkalinity-an essential parameter for water quality monitoring, environmental assessment, and treatment plant operations. By following this standard, laboratories can ensure high precision and comparability in their results, supporting effective water management and regulatory compliance.

Key Topics

Scope and Applicability

Titrimetric determination of carbonate alkalinity in both natural and drinking water sources
Designed for sample concentrations between 0.01 mmol/l and 4 mmol/l
Adaptable to samples with higher alkalinity by using reduced test portions

Method Principles

Utilizes titration with hydrochloric acid to a pH endpoint of 5.4, minimizing interference from other hydrogen acceptors
Offers both pH-meter and indicator-based endpoint detection methods
Simultaneous removal of carbon dioxide ensures a precise and reliable endpoint

Precision and Reliability

Includes guidance for reagent quality, sample handling, and equipment calibration
Statistical data and interlaboratory comparisons support the method’s reproducibility and accuracy

Result Reporting

Standardizes the expression of alkalinity in millimoles per liter
Provides conversion factors for alternative units (e.g., mg/l CaCO₃, German and French degrees)

Applications

SIST EN ISO 9963-2:1998 is widely used in:

Water Treatment Plants: Routine quality control for assessing the buffering capacity of source and treated water

Environmental Monitoring: Regular surveillance of rivers, lakes, and reservoirs to monitor water chemistry and environmental health

Public Health Protection: Ensures drinking water meets regulatory requirements for alkalinity, which can affect taste, pipe corrosion, and suitability for consumption

Research Laboratories: Supports scientific studies requiring precise alkalinity measurements to analyze biochemical and geochemical water properties

The standardized approach enables consistent data generation across different laboratories and countries, aiding international comparison and compliance with water quality regulations.
