ISO/IEC 14776-481:2019 defines a device model that is applicable to all SCSI devices. Other command standards expand on the general SCSI device model in ways appropriate to specific types of SCSI devices. ISO/IEC 14776 (all parts) specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This document is a functional…

This document specifies a method using scanning electron microscopy for determination of the concentration of inorganic fibrous particles in the air. The method specifies the use of gold-coated, capillary-pore, track-etched membrane filters, through which a known volume of air has been drawn. Using energy-dispersive X-ray analysis, the method can discriminate between fibres with compositions…

This document integrates many different types of audio coding: natural sound with synthetic sound, low bitrate delivery with high-quality delivery, speech with music, complex soundtracks with simple ones, and traditional content with interactive and virtual-reality content. This document standardizes individually sophisticated coding tools to provide a novel, flexible framework for audio…

IEC 62941:2019 is applicable to organizations manufacturing photovoltaic (PV) modules certified to IEC 61215 series and IEC 62108 for design qualification and type approval and IEC 61730 for safety qualification and type approval. The design qualification and type approval of PV modules depend on appropriate methods for product and process design, as well as appropriate control of materials and…

IEC 60335-2-62:2019 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 60335-2-62:2019 deals with the safety of electrically operated commercial rinsing sinks used in commercial…

IEC 60335-2-62:2019 deals with the safety of electrically operated commercial rinsing sinks used in commercial kitchens, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances. These appliances are used for example in kitchens of restaurants, canteens, hospitals and commercial enterprises such as bakeries,…

IEC 62823:2015+A1:2019 defines routine and type tests on thyristor valves used in thyristor controlled series capacitor (TCSC) installations for a.c. power transmission. The tests specified in this standard are based on air insulated valves operating in capacitive boost mode or bypass mode. This consolidated version consists of the first edition (2015) and its amendment 1 (2019). Therefore, no…

1 Scope This part of IEC 61730 specifies and describes the fundamental construction requirements for photovoltaic (PV) modules in order to provide safe electrical and mechanical operation. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This part of IEC 61730 pertains to the particular…

1 Scope 1.1 This Standard applies to newly produced gas selector devices (see Clause 3), herein after referred to as a “device”, constructed entirely of new, unused parts and materials. 1.2 The device may include functions such as selection of type of gas to operate the appliance and main burner primary air adjustment. The device may also contain multiple passageways that can be selected to…
