7 Categories of Appliances that require PAT testing and visual inspection

Generally, any portable appliance powered by around 50 and 415 volts and connected to the electrical mains by a cable and plug is classified as a portable appliance requiring testing.

There are seven categories of appliances that are considered for PAT testing or at least visual inspection:

  1. Electrical Appliance– An electrical appliance can quickly move from one place to another. Examples are vacuum cleaners, toasters, microwaves, food mixers, etc. These appliances are less than 18 kg in mass and are intended to move while in operation. They, therefore, require testing at periodic intervals.
  2. Moveable equipment (Transportable) The best examples of this category are equipment’s that is not fixed, weighs 18 kg or less and includes wheels, castors, or other mechanisms that allow operators to move the equipment as needed to carry out its intended use.
  3. Handheld equipment or appliances– This includes standard equipment intended to be handheld during everyday use. Examples are hair dryers, drills, and more.
  4. Stationary appliances– These are the equipment or devices having a mass exceeding 18kg, that are not provided with a carrying handle. Examples are refrigerators and washing machines.
  5. Fixed equipment or appliances– These are equipment or devices that are fastened or secured in a specific location. A good example is the wall mounted heater.
  6. Information Technology Equipments– These electrical types of equipment are used in the office or home for processing, storing, and retrieving data. They include computers, leading powered telecommunications equipment, monitors and photocopiers.
  7. Cords, cables, and chargers are the extension cords, power supply units, and battery chargers.

These seven categories of appliances require PAT testing and visual inspection. Each device has its own set of risks and hazards, so it is essential to have them tested regularly to ensure they are safe to use.

PAT Testing Electrical Classes

PAT testing is vital for all types of electrical equipment and appliances, regardless of class. All electrical equipment and appliances should be tested regularly to ensure they are safe.

Electrical equipment and electrical appliances are classified into three classes:

  • Class I –This class includes appliances that are earthed.  They have a metal chassis which is connected to an earthed power supply. The majority of household appliances are Class I.
  • Class II – Class II appliances are double insulated appliances that do not have an earth connection. These appliance have two layers of insulation and does not require an earth connection. They do not rely on earth for protection, which makes it safer.
  • Class III – This class includes appliances that are supplied by a low voltage power source. These appliances are powered by a low-voltage power source, such as batteries. Class III appliances are usually handheld or portable. They are the safest class of electrical appliances. However, their charging leads need to be PAT tested.

Class 1 includes the most dangerous and common household appliances, such as kettles, toasters, and irons. Class II is for double-insulated appliances, such as most computer equipment. Class III is the least dangerous. It includes electrical equipments with no exposed metal parts, such as some types of transformers.

PAT Testing Procedure

The PAT test procedure is carried out in four steps:

  • Inspection – This involves inspecting the appliance for any damage or wear and tear. It includes checking for cracks, missing parts, loose wires, etc.
  • Testing – The second step is to test the appliance to see if it is safe for use. It includes testing the insulation, earth continuity, and more.
  • Tagging – The third step is to tag the appliance with a PAT Testing label. This label will show the date of the last test, the next due date, and more.
  • Recording – The fourth and final step is to record the test results in a PAT Testing log book. This log book will be used to keep track of all the appliances that have been tested.

By following the four steps of pat testing above, you can ensure electrical safety

The three stages of  PAT Test

PAT testing involves three main stages:

  1. User check– This is when the user checks the appliance for any damage. It involves visually inspecting the external casing, wire, and plug before using it. It is to prevent any apparent faults, like cracks, wire coating, exposed wires, burn marks, or any problems in the plug. 
  2. Visual Inspection– This requires more technical knowledge to complete a thorough visual inspection of the external and internal components of the appliance or equipment. You will need to determine and know how to take a variety of devices apart and tell if any parts or components in internal are damaged or faulty. The appliance manual must be consulted for more comprehensive guidance in these visual inspections.
  3. Combined inspection and test– This is the final stage of pat testing. It involves using specialist PAT testing equipment to assess the appliance parts that cannot be set using visual inspections or checking. It includes testing of appliance insulation and general internal integrity. It can only be completed by a qualified and expert PAT tester.

RB Services will carry out a comprehensive PAT Test on your electrical appliances.

How often do I need to have my appliances tested?

The health and safety experts recommends the following:

  • Class I and II appliances – every 12 months or sooner if used in a hostile environment.
  • Class III appliances – every 24 months or sooner if used in a hostile environment.
  • IT equipment – every 12-24 months, depending on the environment.
  • Transformers, motors, and other similar equipment items are in every 12 months for safety.

There is also need to take the following into consideration:

  • The manufacturer’s recommendations- This may have different testing frequencies than recommended.
  • The age of the equipment-the older the equipment, the more frequently it will need to be tested.
  • The frequency of use-the more often an appliance is used, the more frequently it will need to be tested.
  • The effects of any modifications or repairs – any changes or repairs made to an appliance must be considered when deciding on the testing frequency.
  • The history of the item– if an appliance has a history of faults, it will need to be pat tested more frequently.
  • The type of business- some businesses will require more frequent testing than others.
  • The environment- some environments are more hostile than others and require more frequent testing.
