SIST EN 62391-2-1:2006 is the Slovene standard for fixed electric double-layer capacitors for use in electronic equipment, published by SIST and based on EN 62391-2-1:2006. It is a blank detail specification for electric double-layer capacitors for power application at assessment level EZ, and it tells manufacturers and spec writers what a compliant detail specification must contain.
What does SIST EN 62391-2-1:2006 specify?
SIST EN 62391-2-1:2006 specifies the style, layout, and minimum content of detail specifications for this capacitor family. In practice, it is the template and rule set for writing a product detail specification that matches the IEC 62391 series and is usable for procurement, qualification, and quality control.
The document is organized into:
- Clause 1 - General data
- Clause 2 - Inspection requirements
- Annex ZA - Normative references to international publications with corresponding European publications
Clause 1 covers the information that must appear in the detail specification. Clause 2 sets the inspection and qualification framework. Annex ZA links the document to the referenced IEC and EN publications.
What are the key requirements of SIST EN 62391-2-1:2006?
SIST EN 62391-2-1:2006 requires the detail specification to identify the capacitor clearly and to present its data in a fixed format. The front-page fields [1] to [9] cover the issuing authority, document number, generic specification, capacitor description, construction, outline drawing, application or assessment level, and reference data. For users, this means the document should be complete enough to compare one capacitor type against another without guessing missing basics.
Clause 1.1 to 1.3 require the mounting method, dimensions, and key ratings and characteristics to be stated. Dimensions are tied to Table 1, while rated capacitance, tolerance, rated voltage, climatic category, rated temperature, internal resistance, and leakage current are handled through Tables 2a and 2b. For buyers and designers, this is the core selection data.
Clause 1.4 ties the specification to the normative references in Annex ZA, including IEC 60410, IEC 62391-1, IEC 62391-2, and IEC QC 001005. That matters because the detail specification is not standalone - it depends on the generic and sectional specifications and on the inspection and IECQ framework they define.
Clause 1.5 to 1.7 cover marking, ordering information, and certified records of released lots. Orders must state the rated capacitance, tolerance, direct current (d.c.) voltage, detail specification reference and style reference, and packaging instructions. In practice, this is the minimum information a purchasing system needs to avoid ambiguity.
Clause 1.9 and Table 3 allow additional or more severe characteristics than those in the sectional specification. This is how a detail specification can tighten requirements for a particular application when needed, without rewriting the whole standard.
Clause 2.1 and Table 4 define qualification approval and quality conformance inspection. Table 4 sets lot-by-lot and periodic inspections, sample sizes, acceptance criteria, and the test conditions for checks such as visual examination, dimensions, solderability, high and low temperature characteristics, robustness of terminations, resistance to soldering heat, rapid change of temperature, vibration, endurance, self-discharge, storage at high temperature, damp heat steady state, passive flammability, and pressure relief. For quality teams, this is the testing roadmap.
Table 4 also includes practical rules for factory control. Capacitance may be screened at 100% with follow-up sampling, dimensional checks may be replaced by in-process control if statistical process control (SPC) is in place, solderability is not applicable to terminations not designed to be soldered, and some subgroup failures trigger repeat testing on a new sample.
What terms does SIST EN 62391-2-1:2006 define?
- Blank detail specification - A supplementary document that sets the style, layout, and minimum content for a capacitor detail specification.
- Assessment level EZ - The quality assessment level identified for these electric double-layer capacitors for power application.
- Rated capacitance - The capacitance value that must be stated for ordering and comparison.
- Rated d.c. voltage - The direct current voltage rating used as a key ordering and specification parameter.
- Leakage current - The current value that may need to be specified alongside the capacitor ratings.
- Climatic category - The environmental category that helps define the temperature-related operating range.
- Self-discharge - The loss of stored charge over time, assessed here through retention voltage.
Who uses SIST EN 62391-2-1:2006?
Capacitor manufacturers use SIST EN 62391-2-1:2006 when preparing detail specifications for product families and variants. Quality assurance, inspection, and test laboratories use it for qualification approval and quality conformance inspection. Buyers, design engineers, and spec writers use it to state order data, check markings, and compare capacitor types on the same basis.
What changed in SIST EN 62391-2-1:2006 from the previous edition?
SIST EN 62391-2-1:2006 is the first edition of IEC 62391-2-1:2006. CENELEC approved the IEC text without modification and added Annex ZA.
Which standards are used with SIST EN 62391-2-1:2006?
- IEC 60410 - Provides sampling plans and procedures for inspection by attributes.
- IEC 62391-1 - Gives the generic specification for fixed electric double-layer capacitors.
- IEC 62391-2 - Gives the sectional specification for electric double-layer capacitors for power application and is the main companion document.
- IEC QC 001005 - Provides the IECQ quality assessment system reference used for released and qualified products.
What does the SIST EN 62391-2-1:2006 document contain?
The document contains the blank front-page structure for a detail specification, including identification fields and the capacitor description block. It also contains the general data section with tables for dimensions, ratings, characteristics, and any added or more severe requirements. Clause 2 and Table 4 give the inspection schedule, test methods, sample sizes, and acceptance rules used for qualification and ongoing quality conformance.
