§ Referenced in legislation

ÖNORM EN ISO 13395

Issue date: 1997 01 01

Water quality - Determination of nitrite nitrogen and nitrate nitrogen and the sum of both by flow analysis (CFA and FIA) and spectrometric detection (ISO 13395:1996)

This International Standard specifies a method for the determination of nitrite(N) (see note 2), nitrate(N) or the sum of both [nitrite/nitrate(N)], in various types of waters (such as ground, drinking, surface, and waste waters) in mass concentrations ranging from 0,Ol mg/l to 1 mg/l for nitrite(N) and from 0,2 mg/l to 20 mg/l for nitrite/nitrate(N), both in the undiluted sample. The range of application can be changed by varying the operating conditions. NOTES 1 Seawater may be analysed with changes in respect to sensitivity and adaptation of the carrier solution and calibration solutions to the salinity of the samples. 2 The following concise terms are used in the text of this International Standard: nitrite(N): nitrate(N): nitrite,/nitrate(N): (mass concentration of) nitrite, expressed as nitrogen (mass concentration of) nitrate, expressed as nitrogen (mass concentration of) the sum of nitrite(N) and nitrate(N)

Frequently Asked Questions about ÖNORM EN ISO 13395

What does “§ Referenced in legislation” mean? In which laws is ÖNORM EN ISO 13395 used?

This standard is cited in Austrian laws or regulations and may therefore have binding effect. The citation demonstrates that the standard is used as a recognised basis for meeting legal requirements.

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.
