Rules

SECTION 17D: TECHNICAL REGULATIONS


17.15 SOUND EMISSIONS

17.15.0.1 Sound testing must be carried out at all permitted events however it is not mandatory to test all machines

17.15.1 Specifications

17.15.1.1 Sound emissions are set out in the tables below:

2 Metre Max method

DISCIPLINE LIMIT dB(A)
Enduro & Reliability Trials (including Quads) 112 with a 4dB/A allowance
17.15.1.2 Where government regulations or planning orders exist in relation to lower sound emissions or where a venue has lower sound emission requirements as part of the hire contract, the sound emission required will prevail over GCR 17.15.1.

17.15.2 Sound control during competition

17.15.2.1 The Sound Control Officer (SCO) must arrive in sufficient time for discussions with the Clerk of the Course and other Technical Officials in order that a suitable test site and testing policy can be agreed.
17.15.2.2 Machines can be tested before, or after competing in an event, chosen by ballot, or as required by a Steward, Clerk of Course or SCO.

17.15.3 Use of sound level meters

17.15.3.1 Sound testing apparatus must:

  1. Comply with international standard IEC 651, Type 1 or Type 2.
  2. Include a compatible calibrator, which must be used immediately before testing begins and always just prior to a re-test if a disciplinary sanction may be imposed.
17.15.3.2 Sound testing apparatus must be set to:

  1. ‘Fast response’
  2. ‘A’ weighted,
  3. Select range High 80~130 dB,
  4. Activate the function MAX MIN – set on MAX,
17.15.3.3 ‘2 Metre Max’ Set up of the sound meter and the motorcycle:

  1. The sound levels will be measured with the sound meter/microphone fixed on a tripod, in the horizontal position, at the rear of the motorcycle.
  2. For the place and position of the motorcycle, ensure that there are no solid obstacles within a 10 meter radius of the microphone.
  3. The sound meter will be positioned at a distance of two metre behind the motorcycle, with an angle of 45° away from the centerline, on the exhaust side and at a height of 1.35 metre above the ground, with the sound meter level.
  4. The two metre distance is measured from the point where the centre of rear tyre touches the ground.
  5. It is preferred that the tests are conducted on soft ground, to prevent reverberation, i.e. grass or fine gravel.
  6. In other than moderate wind, machines should face forward in to the wind direction.
  7. The ambient sound level must remain lower than 100 dB/A.
17.15.3.4 ‘2 Metre Max’ Positioning of the motorcycle:
The reference points:

  1. For a motorcycle: the contact point of the rear wheel on the ground.
  2. For motorcycles fitted with two exhaust outputs, the measurement will be made on the side of the air intake. If a central positioned air intake is used, both sides will be tested.
  3. For Sidecars: the contact point of the side wheel on the ground.
  4. For Quad vehicles: the vertical line to the ground from the centre point of the rear axle.
  5. For Quad vehicles with exhaust outlet moved from the median axis, the measurement will be made on the offset side. To make repetitive measurements, all motorcycles can be positioned into a small frame fixed on the ground.
17.15.3.5 ‘2 Metre Max’ method:

  1. The measurement is made with the motorcycle on its wheels, with a hot engine.
  2. During a sound test, machines not equipped with a gear box neutral must be placed on a stand.
  3. The SCO should stand beside the motorcycles, opposite the microphone and not screen or stand between the bike and the microphone. An assistant, placed on the left side of the motorcycle, shall disengage the clutch.
  4. The SCO shall open the throttle as fast as possible until full open throttle (instantly, within 0.3 seconds) and keep at max engine ‘rpm’ for at least one second. To end, the SCO will release the throttle quickly.
  5. If the result exceeds the limit, including ‘after fire’, the Inspector shall test the motorcycle a maximum of 2 more times.
  6. For motorcycles equipped with an engine rpm limiter, opening the throttle will be made – instantly, within 0.3 seconds – and kept open until at least one second has evolved and/or when there is an audible sign of over revving the engine.
  7. For motorcycles without an engine ‘rpm’ limiter, the opening of the throttle will have to be lower than two seconds and/or when there is an audible sign of over-revving the engine.
  8. If the engine tends to suffocate, close the throttle slightly and re-open the throttle.
  9. If detonations appear, the measurement must be started again.
  10. The numbers obtained from the test shall not be rounded down.
  11. For the sound level measurement, the handling of the throttle is limited only to the SCO, who shall open the throttle himself in order to minimize the influence by another operator (for that, it is helpful to have the microphone equipped with an extension cable to the sound meter).
17.15.3.6 Tests shall not take place in the rain

17.15.4 Machine testing

17.15.4.1 If a machine fails, it can be represented for re-testing.
17.15.4.2 No person may compete in any event on a machine whose noise emissions exceed the prescribed levels.
17.15.4.3 A machine which does not comply with the sound limits can be presented several times.

17.16 FUEL

17.16.1.1 Fuels and lubricants are highly specialised substances and participants must be aware they may contain substances that are extremely dangerous to human health if misused, inhaled or allowed to contact skin.
17.16.1.2 Some of the components of fuel and lubricants are suspected of having the potential to cause cancer in rare circumstances.
17.16.1.3 The use of petrol as a general cleaning and washing agent is a common misuse of a potentially dangerous substance.
17.16.1.4 Fuels should be used and stored with extreme care and in accordance with the manufacturer’s instructions.

17.16.2 Fuel Testing

17.16.2.1 For any event, meeting or series, the relevant controlling body may direct that no fuels other than fuels of prescribed specifications and from a prescribed source may be used.

  1. Tests to ensure that only prescribed fuels are used in an event, meeting or series may be administered at any time and place during the course of the same,
  2. The Clerk of Course, Race Director or Chief Scrutineer may direct the administration of fuel tests.
17.16.2.2 Fuel tests must comply with the following procedures:

  1. All containers for holding samples must be clean and constructed of robust non-reactive impermeable material, must be sealable, and must have provision for identification,
  2. Equipment used for the extraction of fuel from machines must be clean and constructed of fuel non-reactive material,
  3. All samples must be divided into two lots (Sample A and Sample B) of not less than 5ml each, which must be placed in separate containers,
  4. Once samples are placed in containers, the containers must immediately be sealed and identified by reference to the machine from which the sample was taken. This information must be entered on a fuel sample certificate which must certify the date, place and time of taking the sample, the identity of the machine from which the sample was taken and the identity of the rider,
  5. Both samples must remain in the control of the official who administered the test.
  6. The rider or the representative must sign the fuel sample certificate acknowledging samples have been taken and are sealed,
  7. All samples held by the official must be delivered as soon as practicable after the competition to the relevant controlling body which must deliver the Sample A as soon as practicable to a laboratory approved by MA where they must be tested for content and quality in accordance with standard scientific procedures,
  8. The relevant controlling body must as soon as practicable after receipt of the results notify the rider or rider’s team representative and MA,
  9. If the rider is dissatisfied with the test result of sample A, they may request sample B be tested at an MA approved laboratory in their presence.

17.16.3 Refuelling

17.16.3.1 During refuelling, each machine must be stationary with the engine stopped.
17.16.3.2 Refuelling will be deemed to have commenced when the fuel tank has been opened and completed when the tank is closed.

SECTION 17D: TECHNICAL REGULATIONS


17.15 SOUND EMISSIONS

17.15.0.1 Sound testing must be carried out at all permitted events however it is not mandatory to test all machines

17.15.1 Specifications

17.15.1.1 Sound emissions are set out in the tables below:

2 Metre Max method

DISCIPLINE LIMIT dB(A)
Enduro & Reliability Trials (including Quads) 112 with a 4dB/A allowance
17.15.1.2 Where government regulations or planning orders exist in relation to lower sound emissions or where a venue has lower sound emission requirements as part of the hire contract, the sound emission required will prevail over GCR 17.15.1.

17.15.2 Sound control during competition

17.15.2.1 The Sound Control Officer (SCO) must arrive in sufficient time for discussions with the Clerk of the Course and other Technical Officials in order that a suitable test site and testing policy can be agreed.
17.15.2.2 Machines can be tested before, or after competing in an event, chosen by ballot, or as required by a Steward, Clerk of Course or SCO.

17.15.3 Use of sound level meters

17.15.3.1 Sound testing apparatus must:

  1. Comply with international standard IEC 651, Type 1 or Type 2.
  2. Include a compatible calibrator, which must be used immediately before testing begins and always just prior to a re-test if a disciplinary sanction may be imposed.
17.15.3.2 Sound testing apparatus must be set to:

  1. ‘Fast response’
  2. ‘A’ weighted,
  3. Select range High 80~130 dB,
  4. Activate the function MAX MIN – set on MAX,
17.15.3.3 ‘2 Metre Max’ Set up of the sound meter and the motorcycle:

  1. The sound levels will be measured with the sound meter/microphone fixed on a tripod, in the horizontal position, at the rear of the motorcycle.
  2. For the place and position of the motorcycle, ensure that there are no solid obstacles within a 10 meter radius of the microphone.
  3. The sound meter will be positioned at a distance of two metre behind the motorcycle, with an angle of 45° away from the centerline, on the exhaust side and at a height of 1.35 metre above the ground, with the sound meter level.
  4. The two metre distance is measured from the point where the centre of rear tyre touches the ground.
  5. It is preferred that the tests are conducted on soft ground, to prevent reverberation, i.e. grass or fine gravel.
  6. In other than moderate wind, machines should face forward in to the wind direction.
  7. The ambient sound level must remain lower than 100 dB/A.
17.15.3.4 ‘2 Metre Max’ Positioning of the motorcycle:
The reference points:

  1. For a motorcycle: the contact point of the rear wheel on the ground.
  2. For motorcycles fitted with two exhaust outputs, the measurement will be made on the side of the air intake. If a central positioned air intake is used, both sides will be tested.
  3. For Sidecars: the contact point of the side wheel on the ground.
  4. For Quad vehicles: the vertical line to the ground from the centre point of the rear axle.
  5. For Quad vehicles with exhaust outlet moved from the median axis, the measurement will be made on the offset side. To make repetitive measurements, all motorcycles can be positioned into a small frame fixed on the ground.
17.15.3.5 ‘2 Metre Max’ method:

  1. The measurement is made with the motorcycle on its wheels, with a hot engine.
  2. During a sound test, machines not equipped with a gear box neutral must be placed on a stand.
  3. The SCO should stand beside the motorcycles, opposite the microphone and not screen or stand between the bike and the microphone. An assistant, placed on the left side of the motorcycle, shall disengage the clutch.
  4. The SCO shall open the throttle as fast as possible until full open throttle (instantly, within 0.3 seconds) and keep at max engine ‘rpm’ for at least one second. To end, the SCO will release the throttle quickly.
  5. If the result exceeds the limit, including ‘after fire’, the Inspector shall test the motorcycle a maximum of 2 more times.
  6. For motorcycles equipped with an engine rpm limiter, opening the throttle will be made – instantly, within 0.3 seconds – and kept open until at least one second has evolved and/or when there is an audible sign of over revving the engine.
  7. For motorcycles without an engine ‘rpm’ limiter, the opening of the throttle will have to be lower than two seconds and/or when there is an audible sign of over-revving the engine.
  8. If the engine tends to suffocate, close the throttle slightly and re-open the throttle.
  9. If detonations appear, the measurement must be started again.
  10. The numbers obtained from the test shall not be rounded down.
  11. For the sound level measurement, the handling of the throttle is limited only to the SCO, who shall open the throttle himself in order to minimize the influence by another operator (for that, it is helpful to have the microphone equipped with an extension cable to the sound meter).
17.15.3.6 Tests shall not take place in the rain

17.15.4 Machine testing

17.15.4.1 If a machine fails, it can be represented for re-testing.
17.15.4.2 No person may compete in any event on a machine whose noise emissions exceed the prescribed levels.
17.15.4.3 A machine which does not comply with the sound limits can be presented several times.
