Overview
IEC 60384-8-1:2005 is the IEC blank detail specification for fixed capacitors of ceramic dielectric, Class 1, at assessment level EZ. It is a supplementary document to the sectional specification (IEC 60384-8) and defines the required style, layout and minimum content for manufacturer detail specifications. Detail specifications that do not follow this blank template may not be considered in accordance with IEC specifications. This second edition (2005) replaces the original edition and subsequent amendments with only minor revisions.
Key topics and requirements
The standard prescribes the structure and mandatory content of a detail specification for Class 1 ceramic fixed capacitors, including:
- Identification and scope
- Title, reference numbers, assessment level (EZ), and QC/IEC identification.
- Product description
- Short description of capacitor type, typical construction and outline drawings (case size references and key dimensions - Table 1).
- Ratings and characteristics
- Required fields such as rated capacitance range, tolerance, rated DC voltage, category/climatic temperature, temperature coefficient and insulation resistance (see Tables 2–4).
- Marking and ordering information
- Component and packing marking requirements and minimum ordering data (capacitance, tolerance, voltage, temp. coefficient, detail spec reference).
- Inspection and test schedules
- Quality conformance and qualification procedures, sampling plans, lot formation and a detailed test schedule (Table 6) including group/subgroup tests, severities, and acceptance criteria.
- Normative references
- Mandatory referenced documents (e.g., IEC 60384-8 sectional spec and IEC 60410 sampling plans).
- Additional clauses
- Sections for certified records, extra requirements, and special characteristics or increased severities.
Applications and users
IEC 60384-8-1:2005 is intended for professionals who create, evaluate or use capacitor detail specifications:
- Capacitor manufacturers - to prepare compliant product detail specifications for Class 1 ceramic capacitors.
- Component engineers and procurement - to verify supplier documentation and ensure interchangeability and traceability.
- Test laboratories and quality assurance teams - to implement the prescribed inspection, sampling and test schedules for qualification and lot acceptance.
- Standards writers and regulatory bodies - as a template to ensure national or industry specifications align with IEC formatting and minimal content.
- Design engineers - to reference consistent ratings, dimensions and performance requirements when selecting components.
