ÖNORM EN ISO 13162

Issue date: 2022 01 15

Water quality - Carbon 14 - Test method using liquid scintillation counting (ISO 13162:2021)

This document specifies a method for the measurement of 14C activity concentration in all types of water samples by liquid scintillation counting (LSC) either directly on the test sample or following a chemical separation. The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater. The detection limit depends on the sample volume, the instrument used, the sample counting time, the background count rate, the detection efficiency and the chemical recovery. The method described in this document, using currently available liquid scintillation counters and suitable technical conditions has a detection limit as low as 1 Bq·l^-1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l^-1). 14C activity concentrations can be measured up to 10^6 Bq·l^-1 without any sample dilution. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

Frequently Asked Questions about ÖNORM EN ISO 13162

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Find out more about the benefits of multi-user licences

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
