Space data and information transfer systems — Space Link Extension — Application Program Interface f...
ISO 18441:2013 defines a C++ Application Program Interface (API) for CCSDS Space Link Extension (SLE) Transfer Services, which is independent of any specific technology used for communications between an SLE service user and an SLE service provider.
ISO 18441:2013 defines the Application Program Interface in terms of:
the components that provide the services of the API;
the functionality…
Mechanical vibration — Methodology for selecting appropriate machinery vibration standards
ISO/TR 19201:2013 provides guidance for selecting appropriate vibration standards for specific machine types, and thus selecting the appropriate vibration measurement and evaluation method. Synopses are given of ISO 10816 (evaluation of machine vibration on non-rotating parts) and ISO 7919 (evaluation of machine vibration on rotating parts), together with further International Standards related…
Measuring relays and protection equipment - Part 26: Electromagnetic compatibility requirements
IEC 60255-26:2013 is applicable to measuring relays and protection equipment, taking into account combinations of devices to form schemes for power system protection including the control, monitoring, communication and process interface equipment used with those systems. This standard specifies the requirements for electromagnetic compatibility for measuring relays and protection equipment. The…
Surge arresters - Part 5: Selection and application recommendations
IEC 60099-5:2013 is not a mandatory standard but 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…

IEC 60286-3:2013 is applicable to the tape packaging of electronic components without leads or with lead stumps, intended to be connected to electronic circuits. It includes only those dimensions that are essential for the taping of components intended for the above-mentioned purposes. This standard also includes requirements related to the packaging of singulated die products including bare die…
IEC 61754-27:2013 defines the standard interface dimensions for the type M12-FO family of connectors. This connector is of duplex plug/adaptor/plug configuration and designed for industrial environment as described in ISO/IEC/TR 29106, severity class M3 and I3. Multiple designs for machines and equipment require solutions with different fibre types. Keywords: standard interface dimensions for the…
Practice for use of a radiochromic film dosimetry system
ISO/ASTM 51275:2013 is a practice for using radiochromic film dosimetry systems to measure absorbed dose in materials irradiated by photons or electrons in terms of absorbed dose to water.
Radiochromic film dosimetry systems are generally used as routine dosimetry systems.
The radiochromic film dosimeter is classified as a Type II dosimeter on the basis of the complex effect of influence…
Practice for use of the alanine-EPR dosimetry system
ISO/ASTM 51607:2013 covers dosimeter materials, instrumentation, and procedures for using the alanine-EPR dosimetry system for measuring the absorbed dose in the photon and electron radiation processing of materials. The system is based on electron paramagnetic resonance (EPR) spectroscopy of free radicals derived from the amino acid alanine.
The alanine dosimeter is classified as a type I…
