This standard covers instructions for conducting and reporting the more generally applicable and acceptable tests to determine the performance characteristics of single-phase induction motors. It is not intended that this standard shall cover all possible tests used in production or tests of a research nature. The standard shall not be interpreted as requiring the making of any or all of the tests described herein in any given transaction.

This standard provides techniques for objective measurement of electroacoustic and voice-switching characteristics of speakerphones that connect directly or indirectly to an analog or digital telephone network. Due to the various characteristics of speakerphones and the environments in which they operate, not all of the test procedures in this standard are applicable to all speakerphones. Application of the test procedures to atypical speakerphones should be determined on an individual basis.

This International Standard gives guidelines for the evaluation and selection of CASE tools, covering a partial or full portion of the software engineering life cycle. It establishes processes and activities to be applied for the evaluation of CASE tools and selecting the most appropriate CASE tools from several candidates. These processes are generic, and organizations must tailor them to meet organizational needs. The CASE tool evaluation and selection processes should be viewed in the larger… read more context of the organization's technology adoption process. This International Standard provides the following: a) guidance on identifying organizational requirements for CASE tools; b) guidance on mapping those requirements to CASE tool characteristics to be evaluated; c) a process for selecting the most appropriate CASE tool from several tools, based on measurements of the defined characteristics. Primary users of this International Standard are organizations that intend to adopt CASE tools to support their software life cycle processes. CASE tool suppliers can also use this International Standard to describe characteristics of their CASE tools. This International Standard is not intended to apply to: a) software engineering frameworks whose purpose is to provide mechanisms for data, control and presentation integration; b) general purpose tools (e.g. word processors, spreadsheets) which can be used in software engineering activities, nor CASE tools of very narrow scope or specific purpose (e.g. a compiler); c) planning for the implementation of CASE tools within an organization (even though it is recognised that this is an important subject). NOTE A user of this International Standard can make the best possible selection of a CASE tool and yet have no guarantee of a successful implementation. ISO/IEC TR 14471 Adoption of CASE Tools addresses this subject. This International Standard contains a set of processes, activities, and tasks designed to be tailored. The tailoring process is the selection of applicable processes, activities and tasks. Compliance with this International Standard is defined as the performance of the processes, activities, and tasks selected from this International Standard for the evaluation and selection project. Any organization imposing this International Standard as a condition of trade is responsible for specifying the minimum set of required processes, activities, and tasks which constitute compliance for a given application of this International Standard. read less

This standard defines the protocol for intercar and intracar serial data communications between subsystems aboard passenger trains. It sets forth the minimum acceptable parameters for a network that can simultaneously handle monitoring and control traffic from multiple systems. While the network itself is not vital, it is intended to be capable of carrying vital messages. This standard will be structured with respect to the OSI seven-layer model.

Since CASE adoption is a subject of the broader technology transition problem, this Technical Report addresses the adoption practices appropriate for a wide range of computing organizations. This Technical Report neither dictates nor advocates particular development standards, software processes, design methods, methodologies, techniques, programming languages, or life-cycle paradigms. This Technical Report will: - identify critical success factors (CSF); - propose a set of adoption processes; - guide successful adoption in consideration of organisational and cultural environment. The following groups are targeted as potential audiences: - CASE users; - information systems managers; - chief information officers (CIO); - CASE suppliers; - software engineering consultants; - those involved in the acquisition of CASE tools and technology. Therefore this Technical Report addresses aspects of CASE tools adoption. It is best used with ISO/IEC 14102 for CASE tool evaluation and selection. It is complementary to related ISO/IEC documents which deal with the general aspects of these topics.

This standard draws on IEEE Std 12207(TM)-2008 to describe system and software reuse processes.1 It describes the relationship of reuse processes to system life cycle processes described in Clause 6 (System Life Cycle Processes) of IEEE Std 12207-2008 and software life cycle processes described in Clause 7 (Software Specific Processes) of IEEE Std 12207-2008. The standard defines processes and specifies requirements for the processes but does not specify particular techniques. The scope of the… read more specified processes is broader than that of IEEE Std 12207-2008 because reuse activities transcend the life cycle of any particular system. The specified processes are suitable on an organization-wide basis. read less
