Prezentul standard stabileşte modul de adoptare a Standardelor internaţionale ISO şi CEI în standardele române, gradele de echivalenţă dintre aceste stan-darde, precum şi organizarea şi redactarea standardelor române prin care sînt adoptate Standarde internaţionale.Prevederile prezentului standard pot fi aplicate prin adaptare şi în cazurile în care prin standardele române se adoptă standarde elaborate de alte organi-zaţii internaţionale.
The purpose of this part of ISO/IEC TR 10000 is to provide the context for functional standardization in support of Open System Environments (OSE). It provides principles and a classification scheme for OSE profiles which may be or have been submitted for ratification as International Standardized Profiles (ISPs).\nISO/IEC TR 10000-1 defines the concept of profiles that are documented as ISPs. This part of ISO/IEC TR 10000 outlines the basic OSE objectives and concepts, and defines an approach and format for OSE profiles specified by International Standardized Profiles. It gives guidance to organizations proposing Draft OSE ISPs, on the nature and content of the documents which may be submitted for ratification as International Standardized Profiles.\nAn OSE is defined as a comprehensive set of interfaces, services and supporting formats (including user aspects) enabling interoperability and portability of applications, data or people, as specified by information technology standards and profiles. Communication protocols are part of the specification of behavior at certain types of interfaces.\nEach OSE profile is created to satisfy a clearly specified set of user requirements. Since profiles will be proposed according to needs identified to SGFS and according to the progress of international base standardization,\nthe Taxonomy will be periodically updated or have new parts added in order to reflect the progress reached. It is also recognized that there will be proposals for the extension of the taxonomy to cover functions which were not identified during the preparation of this edition of ISO/IEC TR 10000. These extensions may be identified by a variety of proposers and involve simple extensions to the existing Taxonomy or the addition of new functional areas not currently covered by ISO/IEC TR 10000. The inclusion of such extensions is administered following the procedures elaborated by SGFS.\nA distinction has been made between a profile and an ISP which documents one or more profiles. The Taxonomy is only concerned with profiles, but further information is given in the \"Directory of ISPs and Profiles contained therein\" as to which ISP contains the documentation of a profile.\nThis Directory is maintained as an SGFS standing document SD-4 (see reference in Annex A). For each draft profile submitted to SGFS, it will also provide additional information, including the status of the identified profiles.
This American National Standard (ANS) describes Auditory Non-Intrusive QUality Estimation Plus (ANIQUE+) objective model, which can be used to estimate the subjective quality of telephone band speech. This ANS can be used to estimate the listening quality of one-way speech transmission. This objective testing method was developed to predict the quailty that would be obtained by subjective listening tests using the Absolute Category Rating (ACR) method at a standard listening level of 79 dB SPL (as per ITU-T P.800 and P.830).
Specifies the standard reference conditions for the purpose of determining the power and fuel consumption of constant speed and variable speed engines.
Specifies the units and limits of accuracy for the purpose of measurement of test parameters of constant speed and variable speed internal combustion engines.
Lays down the guidelines for preparation of the engine for conducting the type tests and performance tests. It also specifies the mode for measurement of wear of critical components of engines for quality assurance purposes.
Specifies the mode of recording of test results of type tests and performance tests conducted according to IS : 10000 (Part Vlll)-1980'Methods of tests for internal combustion engines, Part VIII Performance tests' and IS : 10000 (Part IX)-1980 'Methods of tests for internal combustion engines Part IX Endurance tests', respectively, for both constant speed and variable speed internal combustion engines.
