Steel and iron - Determination of total carbon and sulfur content - Infrared absorption method after combustion in an induction furnace (routine method) (ISO 15350:2000)
This International Standard specifies an infrared absorption method, after combustion in an induction furnace, for
the determination of the total carbon and sulfur content in steel and iron.
The method is applicable to carbon contents of mass fraction between 0,005 % and 4,3 % and to sulfur contents of
mass fraction between 0,000 5 % and 0,33 %.
This method is intended to be used in normal production operations and is intended to meet all generally accepted,
good laboratory practices of the type expected by recognized laboratory accreditation agencies. It uses
commercially available equipment, is calibrated and calibration verified using steel and iron certified reference
materials, and its performance is controlled using normal statistical process control (SPC) practices.
This method can be used in the single element mode, i.e., determination of carbon and sulfur independently or in
the simultaneous mode, i.e., determination of carbon and sulfur concurrently.
Stahl und Eisen - Bestimmung der Gesamtgehalte an Kohlenstoff und Schwefel - Infrarotabsorptionsverfahren nach Verbrennung in einem Induktionsofen (Standardverfahren) (ISO 15350:2000)
Diese Internationale Norm legt ein Verfahren mit Infrarotabsorption nach Verbrennung im Induktionsofen zur
Bestimmung des gesamten Kohlenstoff- und Schwefelgehalts in Stahl und Eisen fest.
Das Verfahren ist anwendbar auf Kohlenstoff, der in Massenanteilen zwischen 0,005 % (m/m) und 4,3 % (m/m)
vorliegt sowie auf Schwefel, der in Massenanteilen zwischen 0,000 5 % (m/m) und 0,33 % (m/m) vorliegt.
Es ist vorgesehen, dass dieses Verfahren im Rahmen der üblichen Produktionsabläufe angewendet wird und
dass es allen allgemein üblichen Laborpraktiken entspricht, die von anerkannten Laborakkreditierungsinstitutionen
erwartet werden. Bei diesem Verfahren werden handelsüblich verfügbare Geräte sowie eine
Kalibrierung und eine Verifizierung der Kalibrierung mit Hilfe zertifizierter Referenzmaterialien für Stahl und
Eisen angewendet, und die Durchführung des Verfahrens wird unter Anwendung der üblichen Praktiken zur
statistische Prozesskontrolle (SPC) überprüft.
Das Verfahren kann im Einelementmodus oder im Simultanmodus angewendet werden, d. h. Kohlenstoff oder
Schwefel können unabhängig voneinander oder gleichzeitig bestimmt werden.
Aciers et fontes - Dosage du carbone et du soufre totaux - Méthode par absorption dans l'infrarouge après combustion dans un four à induction (méthode pratique) (ISO 15350:2000)
La présente Norme internationale spécifie une méthode pour le dosage du carbone et du soufre totaux dans les
aciers et les fontes, par absorption dans l'infrarouge après combustion dans un four à induction.
La méthode est applicable aux aciers et fontes avec des fractions massiques de carbone comprises entre 0,005 %
et 4,3 % et avec des fractions massiques de soufre comprises entre 0,000 5 % et 0,33 %.
La présente méthode est destinée à être utilisée lors d'opérations normales de production et à satisfaire toutes les
bonnes pratiques de laboratoire prévues et acceptées par les organismes reconnus d'accréditation de laboratoires.
Elle fait appel à tout appareillage disponible dans le commerce, est étalonnée et l'étalonnage est vérifié en utilisant
des matériaux de référence certifiés en acier et en fonte. Ses performances sont contrôlées au moyen de
procédures de maîtrise statistique des procédés (MSP).
La présente méthode peut être utilisée de manière séquentielle, c'est-à-dire pour doser individuellement le carbone
et le soufre, ou de manière simultanée, c'est-à-dire pour doser simultanément le carbone et le soufre.
Jeklo in železo - Določevanje celotnega ogljika in žvepla - Metoda z infrardečo absorpcijo po zgorevanju v indukcijski peči (rutinska metoda) (ISO 15350:2000)
Ta mednarodni standard opredeljuje metodo z infrardečo absorpcijo po zgorevanju v indukcijski peči za določevanje celotnega ogljika in žvepla v jeklu in železu. Metoda se uporablja za vsebnost ogljika z masno frakcijo od 0.005 do 4.3 % ter za vsebnost žvepla z masno frakcijo med 0.0005 in 0.33 %. Ta metoda je namenjena uporabi pri običajnih proizvodnih operacijah ter temu, da izpolnjuje vse splošno sprejete dobre laboratorijske prakse tipa, ki ga pričakujejo priznane akreditacijske agencije za laboratorije. Uporablja opremo, ki je na voljo na tržišču, je kalibrirana, kalibriranje pa potrjeno z uporabo jeklenih in železnih certificiranih referenčnih materialov, njena zmogljivost pa se nadzoruje z uporabo običajnih praks statističnega obvladovanja procesov (SOP). Ta metoda se lahko uporablja na način, ki vključuje en element, tj. ločeno določevanje ogljika in žvepla ali na istočasni način, tj. hkratno določevanje ogljika in žvepla.

Foreword
SO (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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

1 Scope
This International Standard specifies an infrared absorption method, after combustion in an induction furnace, for

The method is applicable to carbon contents of mass fraction between 0,005 % and 4,3 % and to sulfur contents of
mass fraction between 0,000 5 % and 0,33 %.
This method is intended to be used in normal production operations and is intended to meet all generally accepted,
good laboratory practices of the type expected by recognized laboratory accreditation agencies. It uses
commercially available equipment, is calibrated and calibration verified using steel and iron certified reference
