SIST EN 60357:2004/A3:2011

SIST EN 60357:2004/A3:2011 is the Slovenian adoption of amendment A3 to EN 60357:2003 for tungsten halogen lamps (non-vehicle), published by SIST. It specifies performance requirements for single-capped and double-capped tungsten halogen lamps up to 250 V, mainly for type testing by lamp manufacturers, responsible vendors, and test laboratories.

What does SIST EN 60357:2004/A3:2011 specify?

SIST EN 60357:2004/A3:2011 specifies performance requirements for non-vehicle tungsten halogen lamps used in projection, photographic, floodlighting, special purpose, general purpose, and stage lighting applications. The document is written around data sheets: some are included in the standard, and some are supplied by the lamp manufacturer or responsible vendor.

The amendment is organized as insertion instructions plus updated data sheets and tables. It updates the material inserted into Section 6 and adds a new data sheet for a G9 lamp type.

What are the key requirements of SIST EN 60357:2004/A3:2011?

SIST EN 60357:2004/A3:2011 is a type-test standard. Its requirements are aimed at checking representative samples, not at defining a production sampling scheme for every manufactured lamp. That matters in practice because the tested sample should reflect normal production and should be close to the center of the production spread.

• The standard applies to single-capped and double-capped tungsten halogen lamps with rated voltages up to 250 V. In practice, that tells a buyer or engineer which lamp family the document can be used for.
• The lamps are intended for specified application groups such as projection, photographic, floodlighting, special purpose, general purpose, and stage lighting. This helps users match the data sheet to the intended service.
• Some requirements refer to the relevant data sheet. For some lamp types the data sheet is inside the standard; for others, the manufacturer or responsible vendor supplies it. This means users must check both the standard and the applicable sheet before testing or ordering.
• The requirements relate only to type testing. The note in the scope explains that the tested sample is expected to represent production, but normal production spread can still place some lamps outside tolerance.
• The amendment inserts updated sheets for several lamp families, including lamps with voltage designations B and C and stage lighting lamps. In practice, this is where users find the specific electrical and mechanical data for each lamp type.
• The new G9 sheet gives the lamp dimensions, the base reference, and the conditions of use. That is what a designer or purchaser needs to confirm fit, heat management, and installation orientation.
• The G9 sheet also links the lamp to an ILCOS code. This supports clear product identification in procurement, catalogues, and technical documentation.
• For the G9 lamp family, the sheet states operating position and thermal limits for the pinch, contact, and bulb. This is important because halogen lamps are sensitive to installation temperature and contact conditions.

What terms does SIST EN 60357:2004/A3:2011 define?

• Single-capped lamp - A lamp with one cap, used in the lamp families covered by the standard.
• Double-capped lamp - A lamp with caps at both ends, also covered by the standard’s scope.
• Type testing - Testing a representative sample to verify performance against the standard’s requirements.
• Relevant data sheet - The sheet that provides the detailed values and conditions for a specific lamp type.
• Rated voltage - The voltage value used to identify and classify the lamp for performance specification.
• ILCOS code - An identification code used to describe the lamp type in a standardized way.
• Responsible vendor - The party that provides the data for a lamp type when the sheet is not included in the standard.

Who uses SIST EN 60357:2004/A3:2011?

SIST EN 60357:2004/A3:2011 is used by lamp manufacturers, responsible vendors, and test laboratories when specifying or checking tungsten halogen lamp performance. It is also useful for quality managers, buyers, and lighting engineers who need to match a lamp type to a particular application such as projection, studio photography, floodlighting, or stage lighting.

What changed in SIST EN 60357:2004/A3:2011 from the previous edition?

This amendment modifies EN 60357:2003. It inserts new pages into publication 60357, replaces the Section 6 contents sheet and page E16, and adds the new data sheet 60357-IEC-6732-1 for general purpose G9 lamps. It also updates the sheet listings for lamp families with voltage designations B and C and for stage lighting lamps.

Which standards are used with SIST EN 60357:2004/A3:2011?

• IEC 60410 - cited for guidance on sampling plans and inspection by attributes when planning type-test sampling.
• IEC 60061-1 - identifies the G9 base referenced on the new data sheet.
• IEC 60357:2002 - the international standard that this amendment updates through Amendment 3.

What does the SIST EN 60357:2004/A3:2011 document contain?

The document contains amendment instructions for inserting new pages into IEC 60357, plus updated sheets for specific lamp families. It includes tabulated data for rated wattage, rated voltage or voltage designation, cap-base, and ILCOS code. The G9 data sheet also gives dimensional drawings and conditions of use, which are the practical design and installation details needed for fitting and testing the lamp.
