Full title and description

ISO 10426-1:2009/Cor 1:2010 — Petroleum and natural gas industries — Cements and materials for well cementing — Part 1: Specification — Technical Corrigendum 1. This document is a one-page technical corrigendum that corrects/clarifies selected editorial and technical items in the published ISO 10426-1:2009 specification for well cements and related materials.

Abstract

This corrigendum (Cor 1:2010) amends ISO 10426-1:2009 by making targeted corrections to the published text of Part 1 (Specification) of the ISO 10426 series. ISO 10426-1:2009 itself specifies chemical and physical requirements, classification and recommended procedures for testing six classes of well cement (classes A, B, C, D, G and H) used in petroleum and natural gas well cementing.

General information

• Status: Published (technical corrigendum)
• Publication date: 15 March 2010 (ISO record: edition 3, 2010 / published April 2010)
• Publisher: International Organization for Standardization (ISO)
• ICS / categories: 75.020 (Extraction and processing of petroleum and natural gas); 91.100.10 (Cement. Gypsum. Lime. Mortar)
• Edition / version: ISO 10426-1:2009 — Corrigendum 1 (Cor 1:2010), applies to Edition 3 (2009/2010)
• Number of pages: 1

Scope

The corrigendum provides corrections and editorial clarifications to ISO 10426-1:2009, which is the specification component of the ISO 10426 series for well cements and materials for well cementing. The base standard covers chemical and physical requirements, classification of well cement types (A, B, C, D, G, H), and references the test procedures used to verify compliance. The corrigendum does not introduce new requirements but corrects the published text to ensure accurate application of the standard.

Key topics and requirements

• Corrections and editorial clarifications to ISO 10426-1:2009 text (technical corrigendum format — one page).
• Specification of well cement classes A, B, C, D (Portland-cement based) and G, H (clinker-based) including chemical and physical criteria.
• Requirements and recommendations for additives, set-modifying agents and chromium(VI) reduction-related chemical handling where applicable.
• References to the test methods and physical testing procedures (detailed testing is covered in ISO 10426-2 and related parts).
• Intended to ensure the published specification is free of errors that could affect interpretation or compliance.

Typical use and users

Used by oil & gas operators, drilling and completion engineers, well-cement manufacturers, quality and compliance laboratories, specification writers, procurement teams and standards bodies. Typical use cases include specifying cement products for well construction, inspecting cement product conformity, contract specifications, and referencing normative requirements in engineering and regulatory documents.

FAQ

Q: What is this standard?

A: It is a technical corrigendum (ISO 10426-1:2009/Cor 1:2010) that corrects or clarifies parts of the ISO 10426-1:2009 specification for cements and materials used in well cementing in the petroleum and natural gas industries.

Q: What does it cover?

A: The corrigendum amends the published text of Part 1 (Specification) to correct editorial or technical errors. The base Part 1 standard defines classification, chemical and physical requirements, and references testing procedures for well cements.

Q: Who typically uses it?

A: Oil and gas operators, well-cement manufacturers, drilling and completion engineers, testing laboratories, procurement/specification teams and standards administrators who rely on ISO 10426-1 for product requirements and conformity assessment.

Q: Is it current or superseded?

A: Cor 1:2010 is a published corrigendum to ISO 10426-1:2009. The base standard (ISO 10426-1:2009) has subsequent corrigenda (for example Cor 2:2012) and the base document was confirmed in ISO review processes; users should refer to the latest edition/corrigenda set for current, authoritative text.

Q: Is it part of a series?

A: Yes — ISO 10426 is a multi-part series addressing specification and testing of cements and materials for well cementing (Parts 1 through at least 6, plus amendments and corrigenda covering testing, deepwater formulations, foamed slurries, shrinkage/expansion, static gel strength, etc.).

Q: What are the key keywords?

A: well cementing, well cement, cement specification, ISO 10426-1, corrigendum, drilling and completion, cement testing, oil and gas.
