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.
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.

INTERNATIONAL STANDARD  ISO ISO 13878:1998(E)
Soil quality — Determination of total nitrogen content by
dry combustion (“elemental analysis”)
1  Scope
This International Standard describes a method for the determination of the total nitrogen of soil after dry
combustion.
It is applicable to all types of soil.
NOTE —  The method was developed originally as a manual method by Dumas [3]. Its applicability is improved greatly due to
the use of modern automated equipment.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
ISO 11464:1994, Soil quality — Pretreatment of samples for physico-chemical analyses.
ISO 11465:1993, Soil quality — Determination of dry matter and water content on a mass basis — Gravimetric
method.
3  Principle
The nitrogen content of a soil pretreated in accordance with ISO 11464 is determined by heating to a temperature of
at least 900 °C in the presence of oxygen gas. Mineral and organic nitrogen compounds are oxidized and/or
volatilized. The combustion products are oxides of nitrogen (NO ) and molecular nitrogen (N ). After transforming all

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération
mondiale d'organismes nationaux de normalisation (comités membres de
l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une
étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l'ISO participent également aux travaux. L'ISO collabore
étroitement avec la Commission électrotechnique internationale (CEI) en
ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l'approbation de 75 % au moins des
comités membres votants.
La Norme internationale ISO 13878 a été élaborée par le comité technique
ISO/TC 190, Qualité du sol, sous-comité SC 3, Méthodes chimiques et
caractéristiques du sol.
Les annexes A et B de la présente Norme internationale sont données
uniquement à titre d’information.

NORME INTERNATIONALE  ISO ISO 13878:1998(F)
Qualité du sol — Détermination de la teneur totale en azote
par combustion sèche («analyse élémentaire»)
1  Domaine d'application
La présente Norme internationale spécifie une méthode de détermination de la teneur totale en azote d’un sol après
une combustion sèche.
Elle est applicable à tous les types de sol.
NOTE —  La méthode, mise au point par Dumas [3], était au départ manuelle. Son mode d’application s’est fortement
amélioré grâce à l’utilisation d’un matériel moderne automatisé.
2  Références normatives
Les normes suivantes contiennent des dispositions qui, par suite de la référence qui en est faite, constituent des
dispositions valables pour la présente Norme internationale. Au moment de la publication, les éditions indiquées
étaient en vigueur. Toute norme est sujette à révision et les parties prenantes des accords fondés sur la présente
Norme internationale sont invitées à rechercher la possibilité d'appliquer les éditions les plus récentes des normes
indiquées ci-après. Les membres de la CEI et de l’ISO possèdent le registre des Normes internationales en vigueur
à un moment donné.
ISO 11464:1994, Qualité du sol — Prétraitement des échantillons pour analyses physico-chimiques.
ISO 11465:1994, Qualité du sol — Détermination de la teneur pondérale en matière sèche et en eau — Méthode
gravimétrique.
3  Principe
La teneur en azote d’un sol, préalablement traité conformément à l’ISO 11464, est déterminée en le chauffant à une
température d’au moins 900 °C en présence d’oxygène gazeux. Les composés minéraux ou organiques de l’azote
sont oxydés et/ou volatilisés. Les produits de la combustion sont des oxydes d’azote (NO ) et de l’azote moléculaire
x
(N ). Après transformation de toutes les formes d’azote en N , la teneur totale en azote est mesurée par
2 2
conductibilité thermique.
4  Réactifs
Tous les réactifs doivent être de qualité analytique reconnue.
4.1  Gaz de combustion (oxygène)
Pour les spécifications particulières, voir le manuel d’utilisation de l’appareil.

4.2  Produits chimiques et/ou catalyseurs, pour la réduction, l’oxydation, le dégagement ou la fixation des gaz
de combustion qui perturbent l’analyse.
4.3  Substances d’étalonnage, par exemple, l’acétanilide (C H NO), l’acide L-aspartique (C H NO ), les acides
8 9 4 7 4
aminés de composition connue ou des échantillons de sol dont la teneur en azote est certifiée.
NOTE —  Il convient que la teneur en azote de la substance d’étalonnage soit aussi proche que possible de celle du sol.
5  Appareillage
5.1  Balance analytique, capable de peser à 0,1 mg près, ou microbalance, capable de peser à 0,01 mg près.
