ISO 10426-5:2004 PDF Download

ISO 10426-5:2004 is a standard that focuses on the determination of the shrinkage and expansion of well cement formulations at atmospheric pressure. The purpose of this standard is to provide methods for testing cement formulations used in petroleum and natural gas industries. The testing is done to measure the dimensional changes that occur during the curing process, specifically the cement hydration.

It is important to note that this standard only covers testing at atmospheric pressure, which means that the results obtained may not reflect the behavior of the cement under actual well cementing conditions where pressure and different boundary conditions are present. As such, ISO 10426-5:2004 is considered a base document that provides a starting point for testing and evaluation of cement formulations, but further testing under more realistic conditions is recommended to obtain accurate results.
