Full title and description

ISO 10426-2:2003 — Petroleum and natural gas industries — Cements and materials for well cementing — Part 2: Testing of well cements, including Amendment ISO 10426-2:2003/Amd 1:2005 (Water‑wetting capability testing). This listing describes the 2003 Part 2 standard together with the 2005 amendment and is presented in PDF format for reference and purchase.

Abstract

ISO 10426-2:2003 specifies requirements and gives recommendations for laboratory testing of cement slurries and related materials under simulated well conditions. The 2005 amendment (Amd 1) adds procedures and/or requirements for assessing water‑wetting capability relevant to well cement performance.

Scope

This part of ISO 10426 describes test procedures, specimen preparation, conditioning and reporting for evaluation of well cements and cement slurries under conditions that simulate downhole pressure, temperature and fluid environments. The amendment specifically provides methods for evaluating water‑wetting capability (important for cement–formation and cement–cement bonding and long‑term zonal isolation performance).

Key topics and requirements

• Standardized preparation and mixing procedures for cement slurries (to ensure repeatable test results).
• Hydration and curing regimes at specified temperatures and pressures representative of well environments.
• Mechanical and physical testing methods (strength, permeability, porosity-related measurements).
• Test apparatus, sample dimensions and conditioning for simulated downhole testing.
• Reporting format and minimum data to document test conditions and results.
• Water‑wetting capability assessment procedures added by Amendment 1 (2005).

Typical use and users

Used by petroleum and natural gas operators, cement manufacturers, laboratory testing service providers, drilling and cementing contractors, research organizations, and regulators to: qualify cement formulations, verify product performance under simulated well conditions, support cementing program design, and provide consistent test data for specification and acceptance.

Related standards

ISO 10426 is a multipart series addressing specification and testing of well cements. Relevant related documents include ISO 10426‑1 (Specification for well cements), ISO 10426‑3 (Testing of deepwater well cement formulations), and later parts addressing other specific test methods (for example Part 5 on shrinkage/expansion). These parts are maintained by ISO/TC 67/SC 3.

FAQ

Q: What is this standard?

A: ISO 10426‑2:2003 is the international standard that defines laboratory test methods and recommendations for evaluating well cement slurries and related materials; Amendment 1 (2005) adds water‑wetting capability testing.

Q: What does it cover?

A: It covers specimen preparation, conditioning, test apparatus, testing procedures under simulated downhole pressure/temperature conditions, and reporting requirements. The 2005 amendment supplements these methods with procedures for assessing water‑wetting capability.

Q: Who typically uses it?

A: Oil and gas operators, cement manufacturers, laboratory and testing houses, cementing service companies, drilling contractors, research institutes and regulators—anyone involved in selection, qualification or testing of well cement systems.

Q: Is it current or superseded?

A: The 2003 edition of ISO 10426‑2 with Amendment 1 (2005) is published and was confirmed as the current edition during ISO’s review cycle; users should check the ISO catalogue for any subsequent revisions or newer parts before final acceptance.

Q: Is it part of a series?

A: Yes — ISO 10426 is a multipart series (e.g., Part 1: Specifications, Part 2: Testing of well cements, Part 3: Deepwater testing, Part 5: shrinkage/expansion, etc.). Each part addresses complementary aspects of well cement specification and testing.

Q: What are the key keywords?
