(Main)Steel and iron - Determination of phosphorus content - Phosphovanadomolybdate spectrophotometric method (ISO 10714:2024)
Steel and iron - Determination of phosphorus content - Phosphovanadomolybdate spectrophotometric method (ISO 10714:2024)
The method is applicable with the following limitations: phosphorus contents between 0,001 0 % (m/m) and 1,0 % (m/m), application ranges and test portions in table 1 depending on the concentration of the interfering elements (arsenic, hafnium, niobium, tantalum, titanium, tungsten).
Stahl und Eisen - Bestimmung des Phosphorgehaltes - Spektrophotometrisches Phosphovanadomolybdat-Verfahren (ISO 10714:2024)
Die vorliegende Internationale Norm legt ein fotometrisches Verfahren zur Bestimmung des Phosphorgehaltes von Eisen und Gusseisen mit folgenden Einschränkungen fest.
Das Verfahren ist bei Phosphoranteilen zwischen 0,001 0 % (Masseanteil) und 1,0 % (Masseanteil) anwendbar.
Aciers et fontes - Détermination des teneurs en phosphore - Méthode spectrophotométrique au phosphomolybdovanadate (ISO 10714:2024)
Le présent document spécifie une méthode spectrophotométrique pour la détermination du phosphore dans les aciers et les fontes.
La méthode est applicable aux teneurs en phosphore comprises entre 0,001 0 % (en masse) et 1,0 % (en masse).
Jeklo in železo - Določevanje fosforja - Fosforovanadomolibdatna spektrofotometrijska metoda (ISO 10714:2024)
Ta metoda se uporablja z naslednjimi omejitvami: vsebnost fosforja med 0,0010 % (m/m) in 1,0 % (m/m), območja uporabe ter preskusni deli v preglednici 1 glede na koncentracijo motečih elementov (arzen, hafnij, niobij, tantal, titan, volfram).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 1, Methods of
determination of chemical composition, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 459, ECISS - European Committee for Iron and Steel Standardization, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 10714:1992), which has been technically
revised.
The main changes are as follows:
