BS EN IEC 61158-5-2:2019 includes the following significant technical changes with respect to BS EN 61158‑5‑2:2014 such as:

ISO 20951 gives an overview and provides guidance on the main methods available to quantify the exchanges of greenhouse gases (CO2

but seeks to give the intentions of the standard in the hope that these

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 BS EN IEC 61158-5-2:2019 includes1 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.
