Common use of Test site Clause in Contracts

Test site. The test site shall consist of a central acceleration track surrounded by a substantially level test area. The test track shall be level; the track surface shall be dry and so designed that rolling sound remains low. On the test site, free sound field conditions shall be maintained to within ±1 dB between the sound source placed in the middle of the acceleration section and the microphone. This condition shall be deemed to be met if there are no large sound reflecting objects such as hedges, ▇▇▇▇s, bridges or buildings within 50 m of the centre of the acceleration section. No obstacle likely to affect the sound field shall be close to the microphone and no one shall come between the microphone and the sound source. The observer taking the measurements shall take up position so as to avoid influencing the metre readings. The surface of the test track shall conform to the requirements of Annex 5 to this Regulation or be in accordance to ISO 10844:2014. After the end of the period indicated in paragraph 10.8 of this Regulation only ISO 10844:2014 shall be used as reference.
