Acts, Regulations and Directives

The Health and Safety at Work Act 1974 (HSW 1974) Sect 6.1 (c) requires that it shall be the duty of any person who designs, manufactures, imports or supplies any article for use at work to supply adequate information about the use for which the article is designed and has been tested, and about any conditions necessary to ensure that it will be safe when being used, cleaned, set maintained dismantled and disposed of.

The EC "Provision and Use of Work Equipment Regulations 1998" places general duties on employers and lists minimum requirements for work equipment to deal with selected hazards whatever the industry.

The Regulations implement an EC Directive aimed at the protection of workers and the "general duties" will require the need to:

What is a PAT Test?
  • A PAT test is a safety test on a regular basis for just about any electrical item with a plug.
  • Detailed records and readings of the tests have to be kept.
  • PAT testing of electrical items is required by health & safety executive and electrical safety acts.
  • Once an item has passed a PAT test a green pass sticker is applied with a retest date.
  • PAT tests should be carried out annually on these items.
  • CD Players, Mixers, Turntables, Amps, Radio Mics, Light Controllers
  • Chasers, EQ's, Cross-Overs, Effects Lights, Smoke Machines, Par Cans,
  • Spot Lights, extension Leads, Bar, Gang plugs, iec/kettle Leads.
  • Many Hotel Groups and Council owned Leisure Centre's normally insist on PAT tested discos.
  • The number of venues insisting on PAT tested equipment is growing.
  • If you cannot prove you are PAT tested you may lose the gig to a competitor who is.
  • Public Liability Insurers will expect you to have a current PAT test certificate.
  • You will be able to advertise to your clients that you are PAT compliant.

Is your equipment Safe?
  • Do you have a current PAT certificate
  • There is a legal and insurance obligation to carry out, on a regular basis, electrical testing to all electrical equipment.
  • You will need one even if you have Public Liability Insurance.
  • If you are a professional band or disco you will understand the need for these legal requirements.
  • Many discos & bands ignore the regulations but in the event of an accident you will be very exposed.
  • "No Win No Fee lawyers" pursue claims vigorously, on behalf of their clients, so be warned!
  • Remember it applies to YOUR safety as well as the public.

How much does it cost?
  • We charge a minimum of £75+vat for up to 10 items but this does cover the travel to and from your base. And for large quantity price can discussed. 
  • Additional items are charged at £2.90 +vat per item and £1.50+vat per lead.
  • Items that are housed in flight cases may need to be removed ready for the test.
  • There will be additional charges per item if removed by the P.A.T. tester.
  • Please prepare equipment for the test by ensuring there is no tape on the leads.
  • We are VAT registered so we do charge vat.
  • The only other cost you may encounter is if a plug is cracked and we fit a new plug in order to pass the item. We replace with high quality plug which are £3.50 each.
  • Failed items will require a repair and retest.
  • We do not make repairs but can advise you where to go for professional repairs.
  • Travel free WITHIN 20 miles radius of Birmingham, additional mileage will be charged beyond.

Method / Procedures

A. Make sure that equipment is suitable for the use that will be made of it.

B. Take into account the working conditions and hazards in the workplace.

C. Ensure equipment is used only for operations for which, and under conditions for which, it is suitable.

D. Ensure that equipment is maintained in an efficient state, in efficient working order and in good repair.

E. Provide equipment that conforms to EC product safety directives.

F. Plus certain other general duties and specific requirements etc.

The words "Work equipment" broadly defines everything from a hand held tool to machines of all kinds.

All testing is carried out to the proposed guide lines HSE / IEE PM 32 Each appliance will be given a unique identification number, then:

In practice approximately 90% of all equipment defects are found during a preliminary visual inspection.
(1) The exterior of the equipment will be inspected for:
  • physical damage.
  • signs of overheating
  • signs of ingress of liquid or foreign materials.
Particular attention will be paid to possible physical damage at accessible mains components such as switches, fuses and appliance couplers.
(2) All mains and power cords, including interconnecting cords, will be checked for physical damage. All flexible cords showing any sign of damage will be replaced at cost + 20%  

(3) Where re-wireable plugs or appliance couplers are used, their covers will be removed, and

  • terminations and cord grips will be checked for tightness.
  • terminations will be checked for correct polarity.
  • conductors will be checked for damage or loose strands.
(4) Operator accessible fuses on the outside of the equipment will be checked for correct type and rating. If the equipment manufacturer has specified a particular rating for the plug fuse, this will also be checked. If the manufacturer has not specified a fuse rating for the plug the preferred fuse size will be determined and the correct size fitted, and check that properly manufactured cartridge fuses to British Standards are used  
(5) Plugs with none insulated pins will be replaced with British Standards approved Insulated ones  
Fuse Replacement
If the manufacturer has not specified a fuse rating for the plug the preferred fuse size ratings are:

Up to 700 watt

The equipment to be tested will normally be constructed in one of two basic classes, designated Class 1, 2. Constructional methods are summarised below, full details being found in BS2754.  

Class 1 equipment will provide the user with two levels of protection. The innermost level is the functional or basic insulation covering live internal parts. The second level of protection is provided by a conductive case, which is earthed. This latter level of protection implies that Class I equipment could be a high hazard potential since it relies on the integrity of an electrical connection (the protective conductor or earth).

Class 2 equipment also provides the user with two levels of protection, both levels being provided by insulation. Such equipment is often described as "double insulated" and should carry the appropriate symbol. The first protective barrier is the functional or basic insulation while the outer protective layer is known as the supplementary insulation, which may comprise either of an insulating internal lining to a conductive case or in the majority of instances, form the case itself.

TESTING EQUIPMENT (Seaward: Supernova / Europa / IT1000


  1. Perform the detailed visual inspection.
  2. Inspect for any damaged components, (these may typically include plugs, sockets, cords, fuse holder, voltage selectors, switches, neon indicators etc).


The first electrical tests will verify the integrity of the protective conductor (the earth) and every part of the conductive case which is designed to be earthed. This is a British Standards Type Approval test. (All IT and electronic equipment should be tested at 100mA this is a safe testing voltage – testing at higher values could degrade the electronics) The guide lines are: 1.5 times the design current of the unit under test but need not be greater than 25Amps the resistance should not exceed 0.1 Ohm, but does not include supply cord / test cord.
Standards Resistance between earth pin on plug to earthed metal parts less supply cord
BS 3456 Household Appliances (0.1 + R) Ohm
BS 4533 Luminaries 0.5 Ohm including supply cord
BS 2769 Handheld motor operated tools (0.1 + R) Ohm
BS 415 Electronic and related apparatus (0.5 + R) Ohm
BSEN 60950 IT equipment (0.1 + R) Ohm



INSULATION RESISTANCE The second electrical test performed is the insulation resistance test. For this test, the PAT testers join together live and neutral and apply a 500v DC voltage between these circuit conductors and earth. Such a test is a requirement of BS2754 "Construction of electrical equipment for protection against electrical shock". This is a British Standards Type Approval test.   Class 2 equipment:- a probe is used to replace the missing earth wire. The probe is placed against the part of the equipment that is normally gripped or touched during use or a part judged most vulnerable to electrical breakdown.   INSULATION RESISTANCE TESTS

LOAD TEST A Load Test is not required by the Standards Authority but is included to protect the test person from the hazards produced by a very low impedance being present between LIVE and NEUTRAL during the following 'operation test' requiring the tester to determine if it is safe to continue testing if a potentially high current is detected.            



EARTH LEAKAGE CURRENT MEASUREMENT A final test will measure the total leakage current from LIVE and/or NEUTRAL to earth under operating conditions. This test is particularly relevant on electronic equipment where 'flash' testing has not been used. Although not a direct substitute for a flash test, the earth leakage test will provide evidence of possible deterioration of certain components under test and may indicate that the method of connection of the equipment to the supply is inappropriate.   Earth Leakage Limits

  EXTENSION LEADS Extension leads should be treated as an appliance and tested in a similar fashion to removable mains IEC leads. They will be given a unique serial number, then:

The following tests are conducted.
Visual inspection
Resistance of the earth conductor
Insulation resistance testing.
Continuity of each conductor.
Polarity of phase, neutral and earth connections.

  As the length of the extension cable will have an effect on the earth resistance, it is recommended that the following limits are observed

a 10 meters 1.0mm sq these limits should not be exceeded unless protected by a 30mA- R.C.D. to BS 7071
b 12 meters 1.25mm sq “Piggy backing” of extension leads is not allowed
c 15 meters 1.50mm sq  
d 25 meters 2.50mm sq  


Documentation System

To make a new log of all Portable Appliances.

  • Identify all equipment with its own unique number. This should be extended to continue and incorporate sequence numbers already in place.
  • Record the test results of all Portable Appliances.
  • Each item that passes as safe is given a second label to identify the Company and the appliance re-test date.
  • Items that are found to be faulty, outside of the normal scope of testing, will have a “ DO NOT USE” label. This failed equipment will be brought to your attention to enable you to make the appropriate decision. We always attempt to leave all equipment operational.
  • Individual fail reports are produced.
  • Ensure that re-tests are carried out at the required frequency.
  • All results can be issued in hard copy.
