Testing of electrical appliances and devices is considered to be mandatory, although the situations in which testing is performed vary as to the extent or precision of the safety test. The guidelines for safety testing are formally referred to as In-service Inspection and Testing of Electrical Equipment, although they are most often known as Portable Appliance Testing (PAT). This reference can be applied to the device being tested as well as the testing equipment itself. The use of plug top PAT test labels is a specific genre of safety reporting for electrical appliances or devices.
PAT testing generally involves the discernment of the status of an appliance or device as to its safe operation. This testing will apply to either the circuitry within the device and its related components or to its connection to the power supply from which it derives its electricity. The need for a system of tracking the use and safety of a device has expanded due to the wider availability of all types of electrical tools and instruments, as well as to the advances in sophisticated circuitry required for the operation of the devices.
The evolution of a means of visually reporting the status of a device has gone from a simple sign or placard posted on a device to the current use of a variety of test labels. These labels are affixed to the device most often, yet there is also a need to apply a label to the lead plug itself in those cases in which the appliance or device is permanently plugged in to the power supply. In these instances, plug top PAT test labels will be used along with any labels affixed to the device itself.
Additionally, there are instances where a plug top PAT test label will be used due to a lack of space on an appliance or device where the label can be affixed without encumbering the use of the device. This is especially true for smaller types of manufacturing tools, such as industrial drills and shears or pneumatic wrenches. A test label will be affixed to the power plug itself rather than to the tool. The label will contain a sufficient amount of information to alert the user as to the safety status of the tool, such as the last date of testing or how long the tool can be used until the next test is due.
Larger electrical appliances and machines will often have a plug top PAT test label affixed to the power lead plug. This method allows for a test result to be displayed without affixing an excessive amount of labels to the appliance or machine. There is a secondary rationale behind the use of a plug top PAT test label in this application, in that the power lead for a major electrical appliance or machine endures less wear during its performance. Consequently, the lead will require fewer inspections.
Plug top PAT test labels are available in various templates. The most basic will display a simple message, such as "passed" or "tested for electrical safety", while others will carry more information, such as the identification number of the inspector and the next testing date.
