IEC 60050-561:2014

Overview

IEC 60050-561:2014, titled International Electrotechnical Vocabulary (IEV) - Part 561: Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control, selection and detection, is an international standard issued by the International Electrotechnical Commission (IEC). This document provides harmonized terms and definitions reflecting the current state-of-the-art for piezoelectric and dielectric devices used in frequency control and signal selection applications. As a horizontal standard, IEC 60050-561:2014 ensures terminology consistency across technical committees and international publications, supporting coherent communication in electrotechnology and electronics.

Key Topics

IEC 60050-561:2014 focuses on key terminology relevant to:

• Piezoelectric Devices: Including resonators and transducers used for precise frequency control.
• Dielectric Devices: Essential in filtering, tuning, and signal selection in electronic circuits.
• Electrostatic Devices: Devices leveraging electrostatic principles for detection and control.
• Associated Materials: Materials commonly used in the construction of these devices, supporting reliability and functionality.

The standard covers:

• Definitions for device parameters such as adjustment tolerance, ageing tolerance, anti-resonance frequency, and centre frequency.
• Detailed descriptions of device components, e.g., bus bar, capacitance ratio, interdigital transducers.
• Terminology arranged by device type and organized in a multilingual format (including terms in several major world languages).

Applications

IEC 60050-561:2014 is widely applicable in various sectors, including:

• Standards Development: Serving as an essential reference for technical committees drafting international, national, or organizational standards related to frequency control, signal processing, and materials science.
• Product Specification and Testing: Ensuring manufacturers and laboratories use standardized vocabulary when describing, testing, and specifying electronic components involving piezoelectric or dielectric elements.
• R&D and Engineering: Supporting scientists and engineers in the clear communication of specifications, test results, and design parameters globally.
• Educational and Reference Materials: Providing a comprehensive and authoritative source of terminology for textbooks, manuals, and online resources in electronic engineering and physics.
• Procurement and Contracts: Facilitating accurate and uniform descriptions in procurement documentation and technical contracts for electronic components and materials.

Adopting IEC 60050-561:2014 helps organizations reduce ambiguity in technical communications, minimize errors in translation, and improve traceability and compliance in international markets.

Related Standards

IEC 60050-561:2014 closely interacts with other specialized standards, including:

• IEC 60050 series: The broader International Electrotechnical Vocabulary (IEV), which includes more than 80 parts covering fields like electromagnetic compatibility (IEC 60050-161) and rotating machines (IEC 60050-411).
• IEC Guide 108: Guidelines for ensuring the coherence of IEC publications and the application of horizontal standards.
• IEC 61994 Glossary series: Glossary standards specific to the field of piezoelectric and dielectric devices, referenced for section titles and additional terminology.
