EN 60064:1995

Overview

EN 60064:1995 - issued by CLC - is the European performance standard for tungsten filament incandescent lamps intended for domestic and similar general lighting services (GLS). The standard defines performance requirements for GLS tungsten filament lamps that already comply with the safety requirements of EN 60432-1. EN 60064 is aligned with IEC documentation (IEC 64:1993, modified) and is indexed under ICS 29.140.20 (Incandescent lamps).

Key Topics

This performance standard addresses the measurable operating and photometric characteristics manufacturers, testers and specifiers use to evaluate tungsten filament GLS lamps. Typical topics covered include:

• Definitions and scope for tungsten filament (incandescent) GLS lamps.
• Rated electrical data and tolerances (rated wattage/voltage and variations under test).
• Photometric performance such as luminous flux and distributions and how they are measured.
• Lifetime and endurance characteristics, including test procedures for lamp life and failure modes.
• Lumen maintenance and depreciation over rated life.
• Color properties (colour temperature and colour rendering) and their assessment.
• Measurement methods and test conditions required to verify performance.
• Marking and identification of lamp type, ratings and relevant information for users and regulators.

Note: EN 60064 defines performance requirements and test procedures, but specific numerical limits or thresholds are contained in the full standard text.

Applications

EN 60064 is intended to ensure reliable, comparable performance of tungsten filament GLS lamps in everyday lighting. Practical applications include:

• Product design and development: guiding lamp manufacturers in specifying performance targets.
• Type testing and quality control: enabling test laboratories and manufacturers to verify compliance with performance criteria.
• Procurement and specification: helping buyers, utilities and installers select lamps that meet expected lumen output, lifetime and colour characteristics.
• Market surveillance and conformity assessment: supporting authorities and certification bodies that validate that lamps placed on the market meet declared performance.

Who uses this standard

• Lamp and lighting manufacturers (product engineers, R&D, QA)
• Independent test laboratories and calibration facilities
• Lighting designers, specifiers and procurement teams
• Regulatory and market surveillance authorities
• Distributors and retailers verifying product claims
