IEC 62384:2006+A1:2009 specifies performance requirements for electronic control gear for use on d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or 60 Hz with an output frequency which can deviate from the supply frequency, associated with LED modules according to IEC 62031. Control gear for LED modules specified in this standard are designed to provide constant voltage or…

IEC 62637-1:2011 defines a charging interface between small handheld multimedia devices and power-supply accessories, specifically chargers. Devices, which could be based on this standard may vary over time, but have to comply with the limited power available. The interface is a 2 mm barrel type charging interface. The French version of this standard has not been voted upon. This bilingual…

ISO 25378:2011 defines general terms for geometrical specifications, characteristics and conditions. These definitions are based on concepts developed in ISO 17450-1 and ISO 22432 and they are given by using a mathematical description based on Annex B of ISO 17450-1:2011. ISO 25378:2011 is not intended for industrial use as such among designers, but is aimed to serve as the "road map"…

ISO 28560-2:2011 specifies a data model and encoding rules for the use of radio frequency identification (RFID) tags for items appropriate for the needs of all types of libraries (including academic, public, corporate, special and school libraries). The rules for encoding a subset of data elements taken from the total set of data elements defined in ISO 28560-1 are based on ISO/IEC 15962, which…

IEC 60679-6:2011 applies to the phase jitter measurement of quartz crystal oscillators and SAW oscillators used for electronic devices and gives guidance for phase jitter that allows the accurate measurement of r.m.s. jitter. In the measurement method, phase noise measurement equipment or a phase noise measurement system is used. The measuring frequency range is from 10 MHz to 1 000 MHz. This…

IEC 60745-2-22:2011 applies to cut-off machines fitted with one bonded reinforced wheel of Type 41 or Type 42, orone or more diamond cut-off wheels with the peripheral gaps, if any, not exceeding 10 mm and with a rated speed not exceeding a peripheral speed of the wheel of 100 m/s at rated capacity and a rated wheel capacity range of 55 mm to 410 mm. These machines are intended to cut materials…

IEC 62040-3:2011 applies to movable, stationary and fixed electronic uninterruptible power systems (UPS) that deliver single or three phase fixed frequency a.c. output voltage not exceeding 1 000 V a.c. and that incorporate an energy storage system, generally connected through a d.c. link. This standard is intended to specify performance and test requirements of a complete UPS and not of…

Scope 1.1 General 1.1.1 This Standard applies to occupational diving operations conducted in connection with all types of work and employment, and describes the requirements for occupational safety. Note: It is recognized that certain underwater tasks may require specialized standards of practice and/or operational techniques that differ from the requirements of this Standard yet may be…

1 Scope 1.1 This Standard specifies requirements for the selection, use, and care of personal protective equipment (PPE) for first responders to a deliberate chemical, biological, radiological, or nuclear (CBRN) incident, including releases and contagious outbreak events. It is specifically targeted to fire, police, and medical first responders/receivers in the front line of the response. 1.2…

1.1 Products that comply with the requirements of this Standard are intended for use as thermal insulation in building construction. This Standard covers requirements and test methods for closed cell polyurethane and polyisocyanurate foam thermal insulation in the form of flat rigid boards covered on both sides with a facing material which impact some physical characteristics. 1.2 This closed…
