Petroleum and natural gas industries. Cements and materials for well cementing - Determination of shrinkage and expansion of well cement formulations at atmospheric pressure subscription-only Preferred severities of the IEC1 Scope This part of ISO 10426 provides the methods for the testing of well cement formulations to determine the dimension changes during the curing process (cement hydration) at atmospheric pressure only. This is a base document, because under real well cementing conditions shrinkage and expansion take place under pressure and different boundary conditions.
