This part of IEC 60079 explains the potential ignition hazard from equipment using optical radiation intended for use in explosive gas atmospheres. It also covers equipment, which itself is located outside but its emitted optical radiation enters such atmospheres. It describes precautions and requirements to be taken when using optical radiation transmitting equipment in explosive gas atmospheres…

This part of IEC 60079 specifies the particular requirements for construction, test and marking for electrical equipment that provides equipment protection level (EPL) Ga. This electrical equipment, within the operational parameters specified by the manufacturer, ensures a very high level of protection that includes rare faults related to the equipment or two faults occurring independently of…

The global automotive industry is increasingly dependent on electronic product data to design and produce vehicles. Because of that dependency, problems with the quality of product data have led to problems in developing and producing products. When its member organisations recognised the problem, the Strategic Automotive product data Standards Industry Group (SASIG) decided the most effective…

Is applicable to electroheat installations such as furnaces for direct arc heating (direct arc furnaces, submerged arc furnaces, ladle arc heating furnaces) and furnaces for indirect arc heating. The contents of the corrigendum of December 2008 have been included in this copy.

This part of CISPR 16 is designated a basic standard, which specifies the characteristics and performance of equipment for the measurement of radio disturbance voltages and currents in the frequency range 9 kHz to 1 GHz. Specifications for ancillary apparatus are included for: artificial mains networks, current and voltage probes and coupling units for current injection on cables. The…

ISO/TR 15403-2:2006 addresses the specifications of natural gas as a compressed fuel for vehicles as an addendum to ISO 15403-1. Specifically, ISO/TR 15403-2:2006 is intended to satisfy requests for quantitative data. The critical items regarding gas composition are water content, sulfur compounds, particulate matter, higher hydrocarbons, CO2, free oxygen, glycol/methanol, oil content and…

This Technical Report is intended as an aid for understanding the libraries specified in Standard ECMA-335, Partition IV: Profiles and Libraries. That Partition includes a machine-readable specification, in XML, of the types that comprise the standard libraries. This Technical Report, in companion files, provides the following items which help to form a traceable chain from the normative XML…

ISO 18369-4:2006 specifies the methods of testing the physicochemical properties of contact lens materials. These are extraction, rigid lens flexure and breakage, oxygen permeability, refractive index and water content.

Specifies a method to measure the conducted electromagnetic emission (EME) of integrated circuits by direct radio frequency (RF) current measurement with a 1 Ω resistive probe and RF voltage measurement using a 150 Ω coupling network. These methods guarantee a high degree of repeatability and correlation of EME measurements. IEC 61967-1 specifies general conditions and definitions of the test…
