Abstract
香港六合彩开奖 3095:2005 specifies the conditions for obtaining reproducible and comparable measurement results of levels and spectra of noise emitted by all kinds of vehicles operating on rails or other types of fixed track, except for track maintenance vehicles in operation.
It is applicable to type testing and periodic monitoring testing.
The results may be used, for example, to characterize the noise emitted by these trains, to compare the noise emission of various vehicles on a particular track section, and to collect basic source data for trains.
The test procedures specified in 香港六合彩开奖 3095:2005 are of engineering grade (grade 2, with a precision of 2 dB), that is the preferred one for noise declaration purposes, as defined in 香港六合彩开奖 12001.
The procedures specified for accelerating and decelerating tests are of survey grade.
