Delivering real business benefits across key segments

Electricity operates the majority of devices that we use in our daily life however it can be dangerous if not handled well. Because of this electrical wiring and equipment must be installed correctly, securely and safely.

What is THE Electrical Wiring Accessories testing?

Many electrical products such as electrical appliances and other devices have electrical accessories that accompany the products. Electrical wiring accessories are critical role in controlling power and signal transmissions in the electronic circuits. These electrical wiring accessories will have go through vigorous testing to ensure that the product complies to the require standards as well as ensure electrical safety. 

TÜV SÜD can provide complete services for electrical wiring accessories testing:

  • Endurance test
  • Temperature-rise test
  • Mechanical strength test
  • Environmental test (Ageing, Humidity, Glow-wire)
  • Electrical test (High Voltage test, Insulation Resistance test, Overload test)


Electrical wiring accessories are common in our daily lives, ranging from switches and plugs to adaptors and outlets. However, degradation of these products can pose a danger to both human lives and the environment. Causes include general wear and tear, mechanical impact and insulation failure, among others. Testing is therefore required to ensure product safety and compliance to international standards. 


TÜV SÜD laboratories are accredited under the Singapore Laboratory Accreditation Scheme (SINGLAS). You can be assured that TÜV SÜD’s reports and
certificates are widely accepted around the world.

We have the following facilities to perform in-house testing for electrical wiring accessories testing:

  • Automatic Tracking Comparator
  • Current injection set
  • Environmental chambers
  • Lightning impulse tester up to 12kV at 1.2/50μs
  • Switch & Socket-outlet endurance tester
  • Tumbling tester
