Overview - EN 60679-4-1:1998 / IEC 60679-4-1

EN 60679-4-1:1998 (identical to IEC 60679-4-1:1998) is a blank detail specification for quartz crystal controlled oscillators of assessed quality where conformity is demonstrated by capability approval (IECQ). It is a supplementary document to the sectional specification and defines the minimum content and layout that manufacturers and purchasers should include in a customer detail specification for custom-built or catalogue oscillators.

Key topics and requirements

• Scope & purpose
  • Applies to quartz crystal controlled oscillators (SPXO, VCXO, TCXO, OCXO) supplied as custom or catalogue items whose quality is assessed by capability approval.
  • Intended to be used with IEC 60679-1 (generic) and IEC 60679-4 (sectional).
• Identification and front-page layout
  • Recommended fields (national authority, IECQ number, sectional/generic references, type description, construction notes, outline drawing).
• Ratings and characteristics
  • Mandatory entries for operating temperature range, climatic category, mechanical test severities.
  • Electrical and performance data: nominal output frequency, reference temperature, frequency tolerances, input/output voltages/power, waveform, load, and ageing.
  • VCXO/TCXO/OCXO-specific items: control voltage, pulling sensitivity, linearity, modulation details, oven supply, stabilization time, retrace.
• Marking, ordering and documentation
  • Marking requirements per IEC 60679-1; ordering info must include quantity, detail-spec number, frequency, product code, tolerance and temperature range.
  • Statement on whether certified test records are required.
• Inspection and test structure
  • Defines minimum inspection levels (IL) and acceptance quality levels (AQL) for group and subgroup tests (visual, frequency, output, waveform, input power, ageing, dimensions, hermetic leak tests).
  • Annex B: ageing test guidance - duration sufficient to confirm frequency slope over 5 days, minimum 15 days.
• Quality system linkage
  • Integrates with IECQ capability approval processes (QC numbers referenced).

Practical applications - who uses this standard

• Oscillator manufacturers creating customer detail specifications for capability approval.
• Supplier qualification / procurement teams requiring a standardized detail spec for purchase orders and audits.
• Quality engineers and test labs implementing inspection sampling plans, AQL/IL selection, and certified test records.
• Design engineers and systems integrators seeking consistent oscillator data (frequency tolerance, stability, ageing, OCXO stabilization) for system-level specifications.
• Certification bodies / IECQ auditors using the blank detail spec to evaluate manufacturer capability approval documentation.

Related standards

• IEC 60679-1: Generic specification (use in conjunction)
• IEC 60679-4 (sectional specification) - Capability approval
• IEC 60679-5 / 60679-5-1 - Qualification approval and blank detail for qualification
• IECQ QC numbering (e.g., QC 690101) for capability approval tracking

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60679-4-1 has been prepared by IEC technical committee 49:
Piezoelectric and dielectric devices for frequency control and selection.
It shall be used in conjunction with:
IEC 60679-1/QC 690000: Quartz crystal controlled oscillators of assessed quality – Part 1:
Generic specification
IEC 60679-4/QC 690100: Quartz crystal controlled oscillators of assessed quality – Part 4:
Sectional specification – Capability approval
This International Standard forms the blank detail specification – Capability approval, for quartz
crystal controlled oscillators of assessed quality.

60679-4-1 © IEC:1998 – 5 –
IEC 60679-5 will form the sectional specification – Qualification approval.
IEC 60679-5-1 will form the blank detail specification – Qualification approval.
The text of this standard is based on the following documents:
FDIS Report on voting
49/388/FDIS 49/402/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
The QC number that appears on the front cover of this publication is the specification number
in the IEC Quality Assessment System for Electronic Components (IECQ).
Annexes A and B form an integral part of this standard.
