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 includes

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

The value obtained by such a test method must correspond to the highest vibration values likely to occur under typical and normal working conditions of the machine

The magnitude of the residue (ash content) on ignition at a given temperature is related to the content of mineral constituents in the paper

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

The recommendations of BS 8103-3 apply only to housing where:

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.
