Abstract: These forms are intended to assist the specification writer to present the basic information. In this sense they are "short-form" specifications or "check sheets" and may not include all necessary engineering data or ...

Abstract: This standard includes equations for predicting the flow of compressible and incompressible fluids through control valves.
The equations for incompressible flow are based on standard hydrodynamic equations for Newtonian incompressible fluids. They are not intended for use when non-Newtonian fluids, fluid mixtures, slurries or liquid-solid conve...

Abstract: This standard covers piezoelectric (including ferro-electric) pressure transducers and piezoelectric sound pressure transducers. Pressure and sound-pressure types could be the same instrument differing only in the method ...

Abstract: This standard provides requirements for the specification of self contained electro-hydraulic linear and rotary valve actuators, both double acting and single acting, used for on-off/isolating, positioning and continuous ...

Abstract: This recommended practice provides guidance in the preparation of control drawings for intrinsically safe apparatus, associated apparatus, and intrinsically safe systems.
This recommended practice is intended to be used in conjunction with ANSI/UL 913-1988, "Standard for Safety, Intrinsically Safe Apparatus and Associated Apparatus for Use in C...

Abstract: General Applicability
This standard addresses alarm systems for facilities in the process industries to improve safety, quality, and productivity. The general principles and processes in this standard are intended for use in the lifecycle management of an alarm system based on programmable electronic controller and computer-bas...

Abstract: This standard specifies tests designed to determine the performance of positioners with analog input signals and pneumatic output. The method of evaluation described in this standard specifies the use of an actuator of the ...

Abstract: This recommended practice is provided for the benefit of design engineers and, ultimately, plant operators. Use of this recommended practice will result in a more coherent and useful application of plant alarms for operations personnel. The goal of this recommended practice is to reduce alarm discrepancies, clutter, excessive noise levels, and info...

Abstract: This recommended practice covers piezoelectric acceleration transducers, primarily those used in aerospace test instrumentation.
Terminology used in this document follows ISA-S37.1, Nomenclature and Specification Terminology for Aerospace Test Transducers with Electrical Output, except that additional terms considered applicable to piezoelectri...

Abstract: The standard is intended to assist in the development of design specifications covering the measurement and control of feedwater systems in boilers with steaming capacities of 200,000 lb/h (25 kg/s) or greater. The safe ...
