Common use of Test procedure Clause in Contracts

Test procedure. The engine speed shall be gradually increased from idle to the target engine speed, not exceeding the tolerance band of ±3 per cent of the target engine speed, and held constant. Then the throttle control shall be rapidly released and the engine speed shall be returned to idle. The sound pressure level shall be measured during a period of operation consisting of a maintaining constant engine speed of 1 second and throughout the entire deceleration period. The maximum sound level meter reading during this period of operation, mathematically rounded to the first decimal place, is taken as the test value.

Test procedure. The engine speed shall be gradually increased from idle to the target engine speed, not exceeding the a tolerance band of ±3 ± 3 per cent of the target engine speed, and held constant. Then the throttle control shall be rapidly released and the engine speed shall be returned return to idle. The sound pressure noise level shall be measured during a period of operation consisting of a maintaining maintenance of constant engine speed of 1 second and throughout the entire deceleration period. The , the maximum sound level meter reading during this period of operationreading, mathematically rounded to the first decimal place, is taken as the test value.

Test procedure. The engine speed shall be gradually increased from idle to the target engine speed, not exceeding the tolerance band of ±3 ±5 per cent of the target engine speed, and held constant. Then the throttle control shall be rapidly released and the engine speed shall be returned to idle. The sound pressure level shall be measured during a period of operation consisting of a maintaining constant engine speed of 1 at least one second and throughout the entire deceleration period. The maximum sound level meter reading during this period of operation, mathematically rounded to the first decimal place, is shall be taken as the test value.

Test procedure. The engine speed shall be gradually increased from idle to the target engine speed, not exceeding the tolerance band of ±3 ± 5 per cent of the target engine speed, and held constant. Then the throttle control shall be rapidly released and the engine speed shall be returned to idle. The sound pressure level shall be measured during a period of operation consisting of a maintaining constant engine speed of 1 at least one second and throughout the entire deceleration period. The maximum sound level meter reading during this period of operation, mathematically rounded to the first decimal place, is shall be taken as the test value." Insert a new paragraph 3.2.5.3.2.3., to read:

Test procedure. The engine speed shall be gradually increased from idle to the target engine speed, not exceeding the speed and held constant within a tolerance band of ±3 per cent of the target engine speed, and held constant±5 percent. Then the throttle control shall be rapidly released and the engine speed shall be returned to idle. The sound pressure level shall be measured during a period of operation consisting of a maintaining constant engine speed of at least 1 second s and throughout the entire deceleration period. The maximum sound level meter reading during this period of operation, mathematically rounded to the first decimal place, is shall be taken as the test value.. A measurement shall be regarded as valid only if the test engine speed did not deviate from the target engine speed by more than the specified tolerance of ±5 percent for at least 1 s.
