This document specifies an instrumental method for the routine determination of pH within the range pH 2 to pH 12 using a glass electrode in a 1:5 (volume fraction) suspension of soil, sludge and treated biowaste in water (pH in H2O), in 1 mol/l potassium chloride solution (pH in KCl) or in 0,01 mol/l calcium chloride solution (pH in CaCl2). This International Standard is applicable to all types of soil, sludge and biowaste, for example pretreated in accordance with ISO 11464 or EN 16179.

This document covers functional and technical requirements for design of Industrial Automation and Control Systems (IACS) part of an oil & gas production and/or processing facility.

IACS is the collection of personnel, hardware, and software that can affect or influence the safe, secure, and reliable operation of industrial processes.

This document applies to end-user companies and others that are in need of requirements addressing an open, secure, and interoperable IACS solution that is based on industry standards and practices valid at publication, and that utilise one central control room for operation of the facility.

The IACS architecture described will enable a safe, secure and efficient management of hardware and software, flexible vertical integration of operational technology (OT)/information technology (IT) functions, and low effort horizontal integration of control and monitoring functions between industrial control systems.

This revision of the standard seeks not to prevent use of near-future technology concepts that are currently under development. Example can be IEEE’s ethernet advanced physical layer (APL) communication and time sensitive networking (TSN), open group’s open process automation (OPA), and NAMUR’s open architecture (NOA).
