Standards

This International Standard describes the fundamentals of product certification and provides guidelines for understanding, developing, operating or maintaining certification schemes for products, processes and services. It is intended for use by all with an interest in product certification, and especially by certification scheme owners.

NOTE 1 In this International Standard the term “product” can also be read as “process” or “service”, except in those instances where separate provisions are stated for “processes” or “services”. Definitions of product, process and service are given in ISO/IEC 17065.

NOTE 2 The certification of products, processes and services is a third-party conformity assessment activity (see ISO/IEC 17000) carried out by product ertification bodies. The requirements for product certification bodies are specified in ISO/IEC 17065.

This guide gives guidance on product certification systems by identifying their various elements based on current practices. It is intended for use by product certification bodies and other interested parties wishing to understand systems, , develop, establish or compare third- party product certification, This Guide is not intended to describe all existing forms of product certification, It does not address first and second- party product conformity assessment.

This International Standard specifies general requirements for the competence of providers of proficiency testing schemes and for the development and operation of proficiency testing schemes. These requirements are intended to be general for all types of proficiency testing schemes, and they can be used as a basis for specific technical requirements for particular fields of application.

This document specifies general requirements for the competence and impartiality of proficiency testing (PT) providers and consistent operation of all proficiency testing schemes. This document can be used as a basis for specific technical requirements for particular fields of application.

Users of proficiency testing schemes, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies and others can use these requirements in confirming or recognizing the competence of proficiency testing providers.

This standard establishes the minimum energy performance standards (MEPs) for refrigerating appliances and relevant test method to specify the energy label.  It also specifies the energy label requirements.

This part of ISO/IEC 9314 specifies the Media access control (MAC) , the middle sublayer of the data link layer (DLL) for fiber distributed data interface (FDDI) .FDDI (ISO/IEC 9314) provides a high -bandwidth (100 Mbit/s).general - purpose interconnection among information processing systems, subsystems and peripheral equipment , using fiber optics or other transmission media. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit/s (10 Mbytes/s). FDDI provides connectivity for many nodes distributed over distances of many kilometers in extent . Certain default parameter values for FDDDI (e.g. timer settings) are calculated on the basis of up to 1000 transmission links or up to 200 km total fiber path length (typically corresponding to 5000 nodes and 100 km of dual fiber cable, respectively), however, the FDDI protocols can support much larger networks by increasing these parameter values.

This part of ISO/IEC 18026 provides an overview of different techniques of security gateways, of components and of different types of security gateway architectures, it also provides guidlines for selection and configuration of security gateways.

This part of ISO/IEC 20000 defines the requirements for a service provider to deliver managed services of an acceptable quality for its customers

This part of ISO/IEC 20000 represents an industry consensus on quality standards for IT service management processes . These service management processes deliver the best possible service to meet a customer's business needs within agreed resource levels, i.e. Service that is professional cost-effective and with risks which are understood and managed.

The fieldbus data link layer provide basic time-critical messaging communication between devices in an automation environment. The purpose of this part of IEC 61158 is to define eight distinct and non- interoperable fieldbus Data link protocols. Each protocol defined in this standard is most most closely related to and lies within the field of application of the corresponding services of IEC 61158-3. the fieldbus data link services definition .
