IEC 62931:2017

Overview

IEC 62931:2017 is an international standard published by the International Electrotechnical Commission (IEC) that defines the safety and interchangeability requirements for GX16t-5 capped tubular LED lamps. These lamps are used for general lighting applications and are characterized by having a rated wattage of up to 70 W and a rated voltage up to 190 V ripple-free DC. The standard primarily focuses on type testing to ensure safe operation, reliability, and compliance with international safety norms throughout the design, manufacture, and testing phases.

The IEC 62931:2017 standard covers detailed safety specifications including electrical, mechanical, and thermal requirements. It also complements and references other IEC standards to maintain global harmonization of safety measures in tubular LED lighting technology.

Key Topics

• Scope and Applicability
  Covers non-integrated GX16t-5 capped tubular LED lamps used in various lighting fixtures with rated wattage up to 70 W and voltage up to 190 V ripple-free DC.

• General and Test Requirements
  Establishes the conditions and methods for type testing lamps to validate safety and interchangeability.

• Marking Specifications
  Defines requirements for permanent and durable markings on lamps and packaging, ensuring traceability and user safety information.

• Interchangeability Criteria
  Includes dimensional tolerances, lamp mass, pin configurations, and temperature behavior at operating and non-operating conditions, enabling compatible replacement in lighting systems.

• Protection Against Electric Shock
  Details protection requirements against accidental contact with live parts, including insulation resistance, creepage distances, and clearance measures.

• Mechanical and Thermal Tests
  Encompasses torque testing of lamp caps, temperature rise limits, heat resistance, flame retardance, and lamp bowing under thermal stress.

• Fault Conditions Testing
  Specifies tests for extreme electrical conditions such as overloads, short-circuits, and component failures to verify lamp safety and fault tolerance.

• Ingress Protection and Photobiological Safety
  Addresses lamp resistance to dust and moisture ingress, thermal endurance, and safe levels of UV, blue light, and infrared radiation emissions.

• Information for Designers
  Provides guidelines for controlgear, lampholder, and luminaire design to ensure compatibility and safe operation with GX16t-5 capped tubular LED lamps.
