Oil and gas industries including lower carbon energy - Cements and materials for well cementing - Part 1: Specification (ISO/DIS 10426-1:2026)
ISO 10426-1:2009 specifies requirements and gives recommendations for six classes of well cements, including their chemical and physical requirements and procedures for physical testing.
ISO 10426-1:2009 is applicable to well cement classes A, B, C and D, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of class D cement.
ISO 10426-1:2009 is also applicable to well cement classes G and H, which are the products obtained by grinding clinker with no additives other than one or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction.

Le présent document spécifie des exigences et fournit des recommandations pour 8 classes de ciments de puits, incluant des exigences chimiques et physiques ainsi que des modes opératoires d’essais physiques.
La présente partie de l'ISO 10426 s'applique aux ciments de puits de classes A, B, C et D, obtenus par broyage de clinker de ciment Portland et, si nécessaire, de sulfate de calcium en tant qu’additif incorporé par broyage. Des additifs de traitement peuvent être utilisés lors de la fabrication des ciments de ces classes. Des modificateurs de prise appropriés peuvent être broyés ou mélangés lors de la fabrication du ciment de classe D.
La présente partie de l'ISO 10426 s'applique aussi au ciment de puits de classes G et H, qui sont des produits obtenus en broyant un clinker de ciment sans aucune addition autre que celles de sulfate de calcium sous une ou plusieurs formes, d'eau ou d'additifs chimiques nécessaires à la réduction du chrome (VI).
La présente partie de l'ISO 10426 s'applique également aux ciments composites pour puits de classes K et L, qui sont des produits obtenus par broyage de clinker de ciment Portland et d'une ou plusieurs formes de CaSO4 avec des constituants composites spécifiés, ou par mélange ultérieur de ciment Portland produit séparément avec des constituants composites spécifiés traités séparément.
Le présent document est un supplément à l’API Spec 10A 25ème édition (2019) et à son addendum 1 (novembre 2019) et à son addendum 2 (août 2022), dont les exigences sont applicables avec les exceptions précisées dans le présent document.
Naftna in plinska industrija, vključno z nizkoogljično energijo - Cementi in materiali za cementiranje vrtin - 1. del: Specifikacija (ISO/DIS 10426-1:2026)
ISO 10426-1:2009 določa zahteve in podaja priporočila za šest razredov cementov za vrtine, vključno z njihovimi kemijskimi in fizikalnimi zahtevami ter postopki za fizikalno testiranje.
ISO 10426-1:2009 se uporablja za razrede cementov za vrtine A, B, C in D, ki so proizvodi, pridobljeni z mletjem klinkerja portlandskega cementa in, če je potrebno, kalcijevega sulfata kot dodatka, zmletega skupaj s klinkerjem. Pri izdelavi cementov teh razredov se lahko uporabljajo dodatki za obdelavo. Primerni modifikatorji vezave (set-modifying agents) se lahko zmeljejo skupaj ali zmešajo med proizvodnjo cementa razreda D.
ISO 10426-1:2009 se uporablja tudi za razrede cementov za vrtine G in H, ki so proizvodi, pridobljeni z mletjem klinkerja brez dodatkov, razen ene ali več oblik kalcijevega sulfata, vode ali kemičnih dodatkov, kot je potrebno za zmanjšanje kroma (VI).

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,
