IEC 62499 specifies the testing methods for carbon contact strips used on railway pantographs. Published in 2008, this international standard establishes a comprehensive framework for type tests and routine tests that demonstrate whether a carbon contact strip — permanently attached…
Medical electrical equipment — Exposure index of digital X-ray imaging systems — Part 1: Definitions and requirements for general radiography Patient Safety ConcernWithout a standardized exposure index, overexposure in digital radiography goes unnoticed because images always look good after automatic…
Standardized definitions, calibration, and requirements for the Exposure Index and Deviation Index in digital radiography IEC 62494-1, published in 2008 by IEC Subcommittee 62B (Diagnostic imaging equipment), addresses a fundamental challenge in digital radiography: unlike traditional film-screen systems where optical…
Nuclear instrumentation — Portable X-ray fluorescence analysis equipment utilizing a miniature X-ray tube Radiation Safety FirstUnlike laboratory-based XRF systems that are interlocked and shielded, handheld XRF analyzers are carried by operators and used in uncontrolled environments. This requires redundant safety…
Optical circuit boards — Basic test and measurement procedures — Part 2-4: Optical transmission test for optical circuit boards without input/output fibres Why OCBs MatterOptical circuit boards can increase interconnect bandwidth by 100-1000x compared to copper traces while reducing power…
Industrial process control devices — Radiation thermometers — Part 2: Determination of the technical data for radiation thermometers Why Standardization MattersWithout standardized technical data, users cannot reliably compare radiation thermometers from different manufacturers for a given application. This standard ensures…
Standardized metrological data, measurement conditions, and performance specifications for industrial radiation thermometry IEC/TS 62492-1, published in 2008 by IEC Technical Committee 65 (Industrial-process measurement, control and automation), is a Technical Specification that defines the technical data — particularly metrological data…
Assessment of lighting equipment related to human exposure to electromagnetic fields — Part 1: Results of the EMF measurement campaign Van der Hoofden ProbeThe Van der Hoofden probe is a specialized EMF measurement head designed to simulate the human head…
Evaluating human exposure to electromagnetic fields from lighting equipment — the Van der Hoofden test method and compliance framework IEC 62493, in its second edition published in 2015, provides a comprehensive framework for assessing human exposure to electromagnetic fields (EMF)…
ESL measuring method — Part 1: Capacitors with lead terminal for use in electronic equipment Why ESL MattersIn high-frequency decoupling applications, a capacitor ESL determines its self-resonant frequency (SRF). Above the SRF, the capacitor behaves inductively and loses its decoupling…
