ASME B133.8

Description / Abstract: This Standard is applicable to land-based, or shoreside, barge-mounted gas turbines in single or multiple 1 arrangements, for indoor or outdoor stationary installations. Applications may include, but are not limited to, gas turbine-driven generators, compressors, or pumps, in simple-cycle gas turbines or combined-cycle gas turbines with simple-cycle bypass capabilities.

Gas turbines used for the primary or auxiliary propulsion source in transportation vehicles (airplanes, automobiles, off-road vehicles, ships, etc.) are excluded from this Standard.

Procedures outlined in Section 2 may be used to specify either the sound emissions from the gas turbine only, or the total sound emissions from the site, including, but not limited to, gas turbine-driven equipment and auxiliary equipment. The user's specification must clearly define the equipment for which the noise specification is applicable, especially for combined-cycle plants, where all equipment may not be furnished by the gas turbine manufacturer on a turnkey basis. Unless otherwise stated, the specified noise emissions limits shall include all equipment at the site provided by the gas turbine manufacturer on a turnkey basis.

This Standard does not include specifications addressing exhaust stack exit sound pressure levels, exhaust stack exit sound power levels, or either the presence or absence of tonal components in the emitted acoustic spectrum.
