This verification and validation (V&V) standard is a process standard that addresses all system, software, and hardware life cycle processes including the Agreement, Organizational Project-Enabling, Project, Technical, Software Implementation, Software Support, and Software Reuse process groups. This standard is compatible with all life cycle models (e.g., system, software, and hardware); however, not all life cycle models use all of the processes listed in this standard. V&V processes… read more determine whether the development products of a given activity conform to the requirements of that activity and whether the product satisfies its intended use and user needs. This determination may include the analysis, evaluation, review, inspection, assessment, and testing of products and processes. read less

This recommended practice defines the software reliability engineering (SRE) processes, prediction models, growth models, tools, and practices of an organization. This document and its models and tools are useful to any development organization to identify the methods, equations, and criteria for quantitatively assessing the reliability of a software or firmware subsystem or product. Organizations that acquire software subsystems or products developed with consideration to this recommended practice will benefit by knowing the reliability of the software prior to acquisition. This document does not seek to certify either the software or firmware or the processes employed for developing the software or firmware.

This standard defines an eXtensible Markup Language (XML)-based language, named Fuzzy Markup Language (FML), aimed at providing a unified and well-defined representation of Fuzzy Logic Systems (FLSs). This standard includes an extendable schema that natively defines the basic components of an FLS and enables the modeling of different categories of fuzzy inference engines, including Mamdani [B16], Tsukamoto [B21], Takagi-Sugeno-Kang (TSK) [B20], and AnYa [B5].

This standard defines the general parameters for marking contact wires in OCSs used for electric railway and transit systems. The standard allows for the identification of various contact wires by composition and conductivity as well as by the operating agency using the wire. This standard is intended to provide a method for determining the type of contact wire with regard to the chemical makeup and electrical conductivity. The standard is not meant to replace any other marking and identification system used for contact wire presently being used but instead presents an alternative method of contact wire identification that is concise and easy to interpret.

This standard provides techniques to select wind turbine and wind farm aero acoustic noise measurements, including instrumentation standards and metrology technology, measurement set, measurement procedures, data processing, and noise source data analysis. The scope of measurement covers near-field sound measurement similar to IEC 61400-11 and distance and far-field sound measurement both outside and inside concerned houses or buildings. This standard focuses on amplitude modulation noise,… read more however, guidelines for low-frequency noise including infrasound near-field measurement are provided. IEC 61400-11 provides overall wind turbine noise measurement standards, while this standard focuses more on the aero acoustic noise of wind turbines to avoid overlap with IEC 61400-11. Users of this standard should also be familiar with of ANSI S1.1-1994 (R2004), Acoustical Terminology. read less
