IEC 61300-3-50:2013 describes the procedure to measure the crosstalk of optical signals between the ports of a multiport M x N (M input ports and N output ports) fibre optic spatial switch. The crosstalk is defined as the ratio of the optical power at an output port which comes from the unconnected input port, to the optical power at the output port which comes from the connected input port.…

IEC 62321-1:2013 refers to the sample as the object to be processed and measured. The nature of the sample and the manner in which it is acquired is defined by the entity carrying out the tests and not by this standard. It provides guidance on the disassembly procedure employed for obtaining a sample. This first edition of IEC 62321-1 is a partial replacement of IEC 62321, forming a structural…

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…

IEC 60404-8-4:2013 defines the grades of cold-rolled non-oriented electrical steel strip and sheet in nominal thicknesses of 0,35 mm, 0,50 mm, 0,65 mm and 1,00 mm. It specifies general requirements, the magnetic properties, geometric characteristics and tolerances, and technological characteristics, as well as the inspection procedure. This standard applies to materials supplied in the fully…

ISO 24531:2013 assists ITS standards developers and users of ITS standards who wish to use XML, by providing a consistent definition of the rules and rule references for the use of XML within ITS systems. ISO 24531:2013 defines consistent rules and rule references to provide a framework to be used when implementing XML-based applications in ITS, and particularly in specifying XML in ITS standards…

ISO 2698:2013 specifies dimensions necessary for the mounting of fuel injectors in diesel (compression-ignition) engines. The location of the fuel inlet and leak-off connections, and the dimensions of the clamp are not defined since they vary according to the particular application. ISO 2698:2013 applies to clamp-mounted injectors of types 7 and 28 made of an integral nozzle and nozzle holder…

ISO 19012-1:2013 specifies the use of the marking "Plan" on microscope objectives, and defines the diameter of the sharp region of the primary image of a flat object surface. ISO 19012-1:2013 applies to visual observation using the combination of objective lens, tube lens and eyepiece, as specified by the manufacturer. This marking is consistent with ISO 8578.

CISPR 15:2013 applies to the emission (radiated and conducted) of radiofrequency disturbances from: - all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation; - the lighting part of multi-function equipment where one of the primary…

ISO 6344:2013 specifies a method for determining or testing the grain size distribution of electro-fused aluminium oxide and silicon carbide microgrits P240 to P2500 for coated abrasives as defined in ISO 6344-1. It applies both to those grits used in the manufacture of coated abrasive products and to those grits taken from products for testing purposes.

IEC 61970-456:2013 defines the subset of classes, class attributes, and roles from the CIM necessary to describe the result of state estimation, power flow and other similar applications that produce a steady-state solution of a power network, under a set of use cases which are included informatively in this standard. This standard is intended for two distinct audiences, data producers and data…
