BS EN 60669-1:2008 Standard

BS EN 60669-1:2008 is a British Standard that outlines the safety requirements and testing methods for switches for household and similar fixed electrical installations. This standard applies to switches for controlling lighting, appliances, and other electrical devices in domestic settings.

Scope and Application

The scope of BS EN 60669-1:2008 covers switches with a rated voltage not exceeding 440V AC and a rated current not exceeding 63A. It applies to switches used in both indoor and outdoor locations within the temperature range of -5°C to +40°C. Switches covered by this standard include manually operated switches, remote control switches, touch-sensitive switches, and electronic switches.

Key Requirements

One of the key requirements of BS EN 60669-1:2008 is that the switch should be able to interrupt the circuit under normal conditions without causing excessive arcing or overheating. The standard also specifies mechanical strength, endurance, and resistance to heat, fire, and abnormal operation. Additionally, the switch must comply with specific safety requirements such as protection against electric shock and resistance to damage by water and dust.

Testing and Compliance

To ensure compliance with BS EN 60669-1:2008, switches undergo various tests such as the glow wire test, which evaluates the resistance to fire. Other tests include endurance tests, impact tests, and thermal cycling tests. Manufacturers need to provide documentation proving compliance with the standard, including technical drawings, test reports, and certificates of conformity.

In conclusion, BS EN 60669-1:2008 sets out the safety requirements and testing methods for switches used in household electrical installations. Its scope covers various types of switches, and it establishes criteria for mechanical strength, endurance, and protection against electric shock. Compliance with this standard ensures that switches are safe to use and can withstand normal operating conditions.
