FIRST STOP SAFETY 11
MemoryPAT-Blu Issue 1.2
PLANNING THE TESTS
Before commencing testing, it is advisable to take a few minutes to plan. First of
all work out whether the equipment is Class I or II. Then decide the type of
equipment and the environment it is going to be used in. This will help to
determine how often the inspection and testing has to be carried out. The
Equipment Register then needs to be prepared. Once this is completed, one is
readyto commence Inspection and Testing.
CLASS OF CONSTRUCTION
All equipment that uses mains electricity are either Class I or Class II. Knowing
the Class of the equipment is important when planning the testing.
If the symbol is present on the rating plate the equipment is Class II. If the
symbol is missing, assume that the equipment is Class I. Mains extension
leads and IEC leads are treated as Class1 appliances.
TYPE OF EQUIPMENT
For the purpose of planning, electrical equipment is categorised into 5 types as
shown below. In general, the easier it is to move an appliance, the higher the
chances of damage to it and the more frequently it has to be tested.
Stationary equipment: Refrigerators and washing machines are examples.
Information Technology equipment: This includes computers, VDUs, data
terminals, telephones, printers, fax machines and photocopiers.
Movable (transportable) equipment: Items that are moved occasionally, like
fans and fires would fitin this category.
Portable appliance: These are appliances such as vacuum cleaners, toasters
and kettles which can easily be moved whilst connected to the mains.
Handheld appliance: This is equipment intended to be held in the hand during
normal use like a hair dryer or drill.

FIRST STOP SAFETY 12
MemoryPAT-Blu Issue 1.2
ENVIRONMENT
The location of equipment will have a bearing on the frequency of testing. For
exampleanitemthatisusedinalow-riskenvironmentsuchasanofficewillhave
a much lower risk of damage than an item used on a construction site. Please
see below for various examples.
Low risk: Offices,shops, hotels and nursing homes
Medium risk:Schools
High risk: Factories, commercial kitchens and equipment used by the public.
Very high risk: Construction sites
FREQUENCY OF VISUAL INSPECTION AND TESTING
It is not essential to carry out inspecting and testing every year. Table 1 below
gives some intervals that are recommended in low risk environments, such as
offices, shops, hotels, and nursing homes. (Timescales for other environments
can be found in Appendix I)

EQUIPMENT REGISTER
This form is used to list all the electrical equipment in the business. Information,
such as Class I or II, type of equipment and frequency of test is recorded. A
blankformissupplied,andthiscanbephotocopiedandusedifadditionalsheets
are required. As new equipment is purchased, this needs to be added to the
register.

FIRST STOP SAFETY 13
MemoryPAT-Blu Issue 1.2
FORMAL VISUAL INSPECTION
Once the above preparation work has been carried out, the visual inspection is
quite straightforward. It is important to prepare a Test Record for each piece of
equipment. A sample form is provided that can be photocopied and used as
required. This form will be used to record the history of visual inspection and
testing.
Formal Visual Inspectionis a very important part of making sure that appliances
are safe to use. In fact, the majority of faults can only be found by a good visual
inspection of the appliance. The following is a list of faults to look for:
Cable
Damage to power cable sheath. Any non-standard joints.
Appliance
Signs that the equipment has been subject to conditions for which it is not
suitable, e.g. wet or excessively rusty.
Cable not being gripped. Damage to external casing.

FIRST STOP SAFETY 14
MemoryPAT-Blu Issue 1.2
Plug external
Cable not being gripped. Damage to mains plug.
Plug internal
In addition to the above, the plug cover (if it is not moulded) needs to be taken
off and check that the cable terminations are correct.
Examples of faults:
Fuse not being used. Bare wires visible.
EARTH WIRE: Green/Yellow
LIVE WIRE: Brown
NEUTRAL WIRE: Blue

FIRST STOP SAFETY 15
MemoryPAT-Blu Issue 1.2
Fuse rating
Check fuse rating. If possible, refer to manufacturer's user guide. Otherwise
follow guidelines below:
3A or 5A fuse fitted: NO action.
13A fuse fitted: Then check power rating.
If power is less than 700 W then fit 3 Amp Fuse.
If power is more than 700 W then NO action.
Examples:
40W rating, requires 3A fuse. 1200W rating, requires 13A fuse.
If the equipment fails on any of the above points, then it must be taken out of
service, a "FAILED" label applied and not used again until it has been properly
repaired and tested.
Under no circumstances must one proceed with the testing stage, if a
failure is found during the Formal Visual Inspection stage.

and carry on with the main testing by pressing the Class I button again. If the
user does neither then the unit should abort this test and power down.
The test will now run and the display will show the test results for the Insulation
Resistance and Earth Continuity tests as well as an overall Pass or Fail. The
image below shows the result of a test that shows a pass. The test number on
the last line (188 in this example) increments automatically for each test. The
user should make a note of this unique number in the test records against the
appliance being tested.
Here is a result that results in a fail due to the Earth Continuity being too high.

FIRST STOP SAFETY 18
MemoryPAT-Blu Issue 1.2
Once the testing is complete, record the results in the Test Record making sure
to include the unique test number. The results are also saved in the memory of
the PAT tester for later retrieval.
Note 1: When the tests are performed, it is important to flex the power lead to
make sure that any loose connections are stressed and are picked up by the
test. The Earth Continuity test is repeated automatically to look for this.
Note 2: On some appliances, paint, rust or scale will prevent a good earth. It is
important to persevere and try and get a good earth connection when carrying
out this test.
