ISO 8312:2015 defines stearic acid (including blends of stearic and palmitic acid) for use as a compounding ingredient in the rubber industry and specifies the test methods for describing its properties. Classification of stearic acid and stearic acid/palmitic acid blends according to iodine value and typical chemical and physical properties for such materials for use in the rubber industry are…

ISO 17244:2015 specifies a method for determining the effects of chemical and aqueous samples on the embryo-larval development of marine bivalves. It allows the determination of the concentration levels that result in an abnormality in embryo-larval development. This test is suitable for salinity ranges between 20 and 40 for mussels and between 25 and 35 for oysters. This method applies to…

IEC 60599:2015 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60599:2015 describes how the concentrations of dissolved gases or free gases may be interpreted to diagnose the…

IEC 60599:2015 describes how the concentrations of dissolved gases or free gases may be interpreted to diagnose the condition of oil-filled electrical equipment in service and suggest future action. This standard is applicable to electrical equipment filled with mineral insulating oil and insulated with cellulosic paper or pressboard-based solid insulation. Information about specific types of…

IEC 62680-2-1:2015 defines an industry-standard USB. The specification describes the bus attributes, the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this standard. The goal is to enable such devices from different vendors to interoperate in an open architecture. The…

IEC 60534-8-4:2015 establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe. The noise may be generated both by normal turbulence and by liquid cavitation in the valve. Parts of the method are based on fundamental principles of acoustics, fluid mechanics, and mechanics. The method…

IEC 61987-21:2015 provides a characterization for the integration of automated valves, including control valves, automated on/off-valves and process regulators, in the Common Data Dictionary (CDD); generic structures in conformance with IEC 61987-10 for Operating Lists of Properties (OLOPs) and Device Lists of Properties (DLOPs) of final control elements.

IEC 61987-22:2015 provides Operating Lists of Properties (OLOP) for the description of the operating parameters and the collection of requirements for valve body assemblies and process regulators, Device Lists of Properties (DLOPs) for the description of various types of valve body assemblies and process regulators.

IEC 61987-23:2015 provides Operating Lists of Properties (OLOPs) for the description of the operating parameters and the collection of requirements for valve actuators, Device Lists of Properties (DLOPs) for valve actuators.

IEC 61987-24-1:2015 provides Operating Lists of Properties (OLOPs) for the description of the operating parameters and the collection of requirements for valve/actuator accessories, that can be used for every valve/actuator accessory, Device Lists of Properties (DLOPs) for positioners and I/P converters.
