Medical electrical equipment - Part 2-1: Particular requirements for the basic safety and essential ...
IEC 60601-2-1:2009+A1:2014 applies to the basic safety and essentialperformance of electron accelerators in the range 1 MeV to 50 MeV, used for treatment of patients. This particular standard establishes requirements to be complied with by manufacturers in the design and construction of electron accelerators for use in radiotherapy; it does not attempt to define their optimum performance…
Specification for radio disturbance and immunity measuring apparatusand methods - Part 4-5: Uncertai...
CISPR TR 16-4-5:2006+A1:2014 specifies a method to enable product committees to develop limits for alternative test methods, using conversions from established limits. This method is generally applicable for all kinds of disturbance measurements, but focuses on radiated disturbance measurements (i.e. field strength), for which several alternative methods are presently specified. These limits…
Rolling bearings — Thrust bearings — Geometrical product specification (GPS) and tolerance values
ISO 199:2014 specifies dimensional characteristics, limit deviations from nominal values, and tolerance values to define the interface (except chamfers) of thrust rolling bearings. Nominal boundary dimensions are defined in ISO 104.
Gas analysis — Preparation of calibration gas mixtures using dynamic methods — Part 2: Piston pumps
ISO 6145 comprises a series of International Standards dealing with various dynamic methods used for the preparation of calibration gas mixtures. ISO 6145-2:2014 describes a method and preparation system using piston pumps. The mixture composition and its associated uncertainty are based on calibration of the piston pumps by dimensional measurements.
The calibration gas mixtures prepared using…
Industrial communication networks - Fieldbus specifications - Part 2: Physical layer specification a...
IEC 61158-2:2014 specifies the requirements for fieldbus component parts. It also specifies the media and network configuration requirements necessary to ensure agreed levels of data integrity before data-link layer error checking and interoperability between devices at the physical layer. The fieldbus physical layer conforms to layer 1 of the OSI 7-layer model as defined by ISO 7498 with the…
Terminology for voltage-sourced converters (VSC) for high-voltage direct current (HVDC) systems
IEC 62747:2014 defines terms for the subject of self-commutated voltage-sourced converters used for transmission of power by high voltage direct current (HVDC). The standard is written mainly for the case of application of insulated gate bipolar transistors (IGBTs) in voltage sourced converters (VSC) but may also be used for guidance in the event that other types of semiconductor devices which…
Road vehicles — Liquefied natural gas (LNG) fuel system components — Part 7: Pressure relief valve
ISO 12614-7:2014 specifies tests and requirements for the pressure relief valve (PRV), a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833. ISO 12614-7:2014 is not applicable to the following:
a) fuel containers;
b) stationary gas engines;
c) container mounting hardware;
d) electronic fuel management;
e) refueling…
Cutting tool data representation and exchange — Part 80: Creation and exchange of 3D models — Overvi...
ISO 13399-80:2014 specifies the basic principles for the creation and exchange of simplified 3D models of cutting items, tool items, and adaptive items, using related properties and domains of values. Simplified 3D models contain the following: naming and defining of the basic design features of cutting items, tool items, and adaptive items, with an association to the used properties; naming and…
Non-destructive testing — Ultrasonic testing — Technique of testing claddings produced by welding, r...
ISO 17405:2014 specifies the techniques for manual ultrasonic testing of claddings on steel applied by welding, rolling, and explosion using single-element or dual-element probes. The test is intended to cover detection of two-dimensional or three-dimensional discontinuities in the cladding and in the region of the interface.
ISO 17405:2014 does not give acceptance criteria nor define the extent…
Heavy commercial vehicles and buses — Stopping distance in straight-line braking with ABS — Open loo...
ISO 16552:2014 describes test methods for determining the stopping distance during a straight-line braking manoeuvre with the braking system fully operational. It applies to heavy vehicles equipped with an anti-lock braking system (ABS), including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above…
