IEC 60642:1979

IEC 60642:1979 defines the technical framework for piezoelectric ceramic resonators and resonator units used for frequency control and selection. For engineering, testing, and procurement teams, IEC 60642:1979 is a useful reference when evaluating device characteristics, comparing supplier documentation, and aligning verification activities with consistent measuring and test conditions. Its focus on standard values and test conditions makes it relevant wherever technical review and documented evaluation are needed for frequency-sensitive electronic components.

Purpose of IEC 60642:1979

The purpose of IEC 60642:1979 is to establish common reference conditions for the specification, measurement, and testing of piezoelectric ceramic resonators and resonator units. By defining standard values and measuring and test conditions, it supports operational consistency across laboratories and product qualification workflows. This helps reduce ambiguity during technical validation, improves comparability of results, and gives engineers and compliance teams a clearer basis for conformity assessment and product evaluation.

Compliance applications of IEC 60642:1979

In practice, IEC 60642:1979 may be used in component procurement, design verification, incoming inspection, and supplier quality workflows for frequency control and selection devices. It is relevant to laboratories and manufacturers that need repeatable test conditions when assessing resonator performance or preparing technical documentation. The document can also support regulatory preparation and internal quality assurance where consistent measurement methods are important for technical assessment and review of electrical component data.

Benefits of IEC 60642:1979

Using IEC 60642:1979 can improve testing consistency, reduce interpretation differences between parties, and support more reliable comparison of device data across projects or suppliers. For organizations managing compliance workflows, it provides a structured basis for engineering validation and procurement review, helping teams assess whether a part has been evaluated under recognized conditions. That can lower technical risk, strengthen documentation quality, and make conformity assessment preparation more efficient.
