This document specifies required characteristics of a domain-neutral top-level ontology (TLO) that can be used in tandem with domain ontologies at lower levels to support data exchange, retrieval, discovery, integration and analysis. If an ontology is to provide the overarching ontology content that will promote interoperability of domain ontologies and thereby support the design and use of…

IEC 60695-6-1:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60695-6-1:2021 gives guidance on: a) the optical measurement of obscuration of smoke; b) general aspects of…

IEC 60695-6-1:2021 gives guidance on: a) the optical measurement of obscuration of smoke; b) general aspects of optical smoke test methods; c) consideration of test methods; d) expression of smoke test data; e) the relevance of optical smoke data to hazard assessment. This basic safety publication focusing on safety guidance is primarily intended for use by technical committees in the…

IEC 62153-4-15:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62153-4-15:2021 specifies the procedures for measuring with triaxial cell the transfer impedance, screening…

This document addresses the system design of pipe and joints of above ground installations without end-thrust as specified in systems standard ISO 23856. It is directed to pipelines with a minimum stiffness of SN 5000 laid in a straight line between thrust blocks. It is based on the safety concepts described in ISO TS 20656-1, with consequence class 2 (CC2) as default. For other consequence…

1 Scope 1.1 This Standard covers atmospheric vacuum breakers (AVB). 1.2 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with each Standard in the Series; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible…

Scope IEC 60601-1:2005+Amd 1:2012, 1.1 is replaced by: This document specifies particular requirements for the BASIC SAFETY and ESSENTIAL PERFORMANCE of a RESPIRATORY GAS MONITOR (RGM), hereafter referred to as ME EQUIPMENT, intended for CONTINUOUS OPERATION for use with a PATIENT. This document specifies requirements for — anaesthetic gas monitoring, — carbon dioxide monitoring, and —…

1 Scope 1.1 This Standard applies to open-type (fused and solid-blade) cutouts with a polymeric insulator structure component. These cutouts are intended for operation on alternating current distribution systems. 1.2 In some cases, specific types of construction are envisaged. This does not preclude the use of other types of construction, provided that the engineering representatives involved…

1 Scope This part of IEC 61400 specifies essential design requirements to ensure the structural integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. This document is concerned with all subsystems of wind turbines such as control and protection functions, internal electrical systems, mechanical…
