IEC 60642:1979/AMD1:1992

IEC 60642:1979/AMD1:1992 defines Amendment 1 to the requirements for piezoelectric ceramic resonators and resonator units for frequency control and selection, with a focus on standard values and measuring and test conditions. It is relevant where engineering teams need a clear compliance reference for documenting device characteristics, comparing test results, and supporting technical validation. For organizations working with frequency-control components, IEC 60642:1979/AMD1:1992 helps align review, procurement, and laboratory evaluation activities with a consistent technical basis.

What is IEC 60642:1979/AMD1:1992?

This amendment modifies the parent document IEC 60642:1979 and is best understood as a supporting technical reference rather than a standalone specification. Its title indicates a focus on piezoelectric ceramic resonators and resonator units used for frequency control and selection, together with the standard values and test conditions used to assess them. In practice, it may be used to support documented evaluation, verification activities, and conformity assessment where consistent measuring conditions are important for reliable comparison.

Applications of IEC 60642:1979/AMD1:1992

IEC 60642:1979/AMD1:1992 is typically relevant in product evaluation, laboratory testing, and engineering documentation for resonators used in electronic frequency-control functions. It may support technical review in component sourcing, incoming inspection, and qualification testing where repeatable results are needed. The amendment can also be useful in compliance workflows that require traceable test conditions, especially when teams are comparing device behavior across suppliers, test setups, or quality assurance procedures.

Why is IEC 60642:1979/AMD1:1992 important?

For organizations handling piezoelectric resonator specifications, this amendment helps reduce ambiguity in performance assessment by refining the reference conditions used for measurement and testing. That can improve consistency across engineering validation, procurement decisions, and conformity assessment preparation. In controlled testing environments, having a defined technical basis supports risk management, clearer documentation, and more reliable comparison of results, which is valuable when frequency stability and selection characteristics must be evaluated with care.
