11 Item of the certification criteria or higher Test methods and verification methods Consumer information Verification of submitted documents 7.3 Method to measure noise (sound pressure level) Noise shall be measured in the following conditions in accordance with KS I ISO Sound level meter It means a sound level meter specified in KS C Measuring conditions Noise shall be measured in a stable state by operating at 80 % of rated capacity and rated voltage under the general installation conditions Measurement of noises in the boiler body Measure the weighting network A characteristics for three times with a sound level meter at a height of 1.2 m from the bottom surface of a position from a distance of 1.5 m from both sides of the product and the central portion of the rear surface of the product. However, the surface on which an air blower exists shall not be measured Measurement of noises in the air blower Measure the weighting network A characteristics for three times with a sound level meter defined in at a position 1.5 m away from the front side of the air blower Indication of the test result Indicate the maximum noise value among the average noise value measured at each point in accordance with and as the noise value of the boiler body or air blower. However, in case that it is difficult to take a single value due to extreme changes in noise levels, equivalent noise may be used. In order to measure the equivalent noise, if required, operating time may be changed within a range that does not change the characteristics of the products. 5
