Tip: IEC 61710 provides the statistical foundation for modelling the reliability of repairable systems using the power law (Weibull process) model. It is an essential reference for reliability engineers working with failure time data from systems that undergo repairs or…
Tip: IEC 61713 provides a comprehensive framework for managing software dependability across the entire system life cycle, from concept through development, operation, and decommissioning. It bridges the gap between general dependability concepts (IEC 60300 series) and software-specific engineering practices. 1.…
Tip: IEC TS 61724-3 defines a standardized methodology for evaluating the energy performance of photovoltaic (PV) systems. It is the essential reference for commissioning tests, performance guarantee verification, and ongoing monitoring of grid-connected PV power plants. 1. Scope and Purpose…
IEC 61691-3-2:2001 is the international adoption of the IEEE 1076.3 VHDL math packages standard. It defines the mathematical extension packages that transformed VHDL from a language capable of only basic logic operations into a powerful platform for DSP, control, and…
IEC 61701:2011 is the essential standard for qualifying photovoltaic modules for installation in coastal environments and other locations exposed to salt-laden atmospheres. As global PV deployment increasingly extends into offshore, coastal, and agricultural-adjacent areas, this standard has become critical for…
IEC 61702:1995 addresses a fundamental yet often overlooked aspect of PV system design: how to optimally connect a solar array directly to a load without an intermediate maximum power point tracker. This standard is particularly relevant for low-cost, high-reliability applications…
IEC 61703:2016 is the definitive mathematical reference for reliability engineering, providing standardized expressions for reliability, availability, maintainability, and supportability (RAMS) metrics used across all engineering disciplines. Introduction IEC 61703:2016, titled “Reliability — Mathematical expressions for reliability, availability, maintainability and maintenance…
IEC 61683 remains the foundational reference for efficiency measurement of PV inverters. Despite its 1999 publication date, the efficiency measurement methodology defined in this standard is still referenced by modern standards including IEC 62891 and IEC 62446. Introduction IEC 61683:1999,…
IEC 61685 is the definitive international standard for ultrasonic flow measurement, providing a comprehensive framework for both transit-time and Doppler-based systems used in medical, industrial, and environmental applications. Introduction IEC 61685:2001, titled “Ultrasonics — Flow measurement systems — Flow test…
IEC 61689:2013 is the globally recognized benchmark for therapeutic ultrasound equipment used in physiotherapy. It defines the performance, safety, and measurement requirements that directly impact treatment efficacy and patient safety. Introduction IEC 61689:2013, titled “Ultrasonics — Physiotherapy systems — Field…
