IEC 60099-5:2018 provides information, guidance, and recommendations for the selection and application of surge arresters to be used in three-phase systems with nominal voltages above 1 kV. It applies to gapless metal-oxide surge arresters as defined in IEC 60099-4, to surge arresters containing both series and parallel gapped structure – rated 52 kV and less as defined in IEC 60099-6 and metal-…

IEC 60749-26:2018 establishes the procedure for testing, evaluating, and classifying components and microcircuits according to their susceptibility (sensitivity) to damage or degradation by exposure to a defined human body model (HBM) electrostatic discharge (ESD). The purpose of this document is to establish a test method that will replicate HBM failures and provide reliable, repeatable HBM ESD…

IEC 61125:2018 describes a test method for evaluating the oxidation stability of insulating liquids in the delivered state under accelerated conditions regardless of whether or not antioxidant additives are present. The duration of the test can be different depending on the insulating liquid type and is defined in the corresponding standards (e.g. in IEC 60296, IEC 61099, IEC 62770). The method…

IEC TR 61948-3:2018(E) describes test methods for Positron Emission Tomographs (PET). As part of quality control, this document is defining routine tests to be performed by the user of Positron Emission Tomographs to maintain proper operation conditions. The results of these routine tests are compared to the reference data determined during or after acceptance test. Methods used for acceptance…

ISO 18639 series of standards specify requirements of personal protective equipment (PPE) specifically designed to protect firefighters from injury and/or loss of life while engaged in specific rescue activities. ISO 18639 series provides the principles that govern the development of incident type and/or hazard specific minimum test methods including design and performance requirements for…

ISO 20077-2:2018 specifies general rules and basic principles the manufacturer of the extended vehicle (ExVe) considers when elaborating its own design method. It does not specify the manner in which these design methods are drafted and implemented. ISO 20077-2:2018 specifies by means of a template the necessary information that is communicated to the ExVe manufacturer for requesting the design…

1.1 This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the Canadian Electrical Code, Part I, CSA C22.1, in Canada, Standard for Electrical Installations, NOM-001-SEDE, in Mexico, and the National Electrical Code (NEC), NFPA 70, in the United…

This part of ISO/IEC 29794, for any or all biometric sample types as necessary, establishes the following: — terms and definitions that are useful in the specification and use of quality metrics; — purpose and interpretation of biometric quality scores; — encoding of quality data fields in biometric data interchange formats; — methods for developing biometric sample datasets for the purpose of…

This International Standard provides the overview of information security management systems, and terms and definitions commonly used in the ISMS family of standards. This International Standard is applicable to all types and sizes of organization (e.g. commercial enterprises, government agencies, notfor- profit organizations).

1 Scope 1.1 General This Standard specifies requirements for workplace electrical safety necessary for the practical safeguarding of workers during activities such as the installation, removal, inspection, operation, maintenance, and demolition of electric conductors and electric equipment, as well as work in proximity of energized electrical equipment. 1.2 Application While it can be applied…
