ISO 10494:2018 specifies methods for measuring the noise emission of a turbine or turbine set under steady-state operating conditions. It specifies methods for measuring the sound pressure levels on a measurement surface enveloping a source, and for calculating the sound power level produced by the source. It gives requirements for the test environment and instrumentation, as well as techniques for obtaining the surface sound pressure level from which the A-weighted sound power level of the source and octave or one-third-octave band sound power levels are calculated. These methods can be used to conduct performance tests even if the purpose of the test is simply to determine the sound pressure level around the machine. ISO 10494:2018 is applicable to turbines and turbine sets: - for power plant and industrial applications (e.g. stationary); - for installation on board ships, or offshore installations, road and railway vehicles. ISO 10494:2018 does not apply to gas turbines in aircraft applications. ISO 10494:2018 is applicable to only the part of the turbine set (turbine, driven equipment and attached components) located above the floor and inside a continuous enveloping measurement surface bounded by this floor. ISO 10494:2018 is applicable to steady-state operation and excludes transients such as start-up and shut-down, when the noise emission can be higher for short times. Under these conditions, this document does not apply.

It is not applicable to gas turbines used for all types of propulsion including aircraft, mobile barges, floating production vessels and marine propulsion applications and microturbines. ISO 19859:2016 defines the requirements for gas turbine power generation from an international perspective based on the content of existing, recognized ISO and IEC standards to the greatest extent practical. Nonetheless, it is recognized that within the industry other codes or standards are used, some of which are included in the text of this International Standard. The use of other such codes and standards is permissible provided an appropriate and acceptable level of requirements, functional design and safety is achieved and agreement has been reached for their use between the Purchaser and Contractor and such use is suitably documented. Consideration should be given to applying/using standards in the following hierarchical order: international; regional; national; local. ISO 19859:2016 identifies the requirements for both the Purchaser and Contractor attributable to the design and procurement of a gas turbine power generation package. The defined requirements apply to the scope of supply, except where excluded, encompassing the following equipment and the associated selected options, located within the power generation package, (see 3.14), listed below: - gas turbine package; - load shaft coupling and clutch, as applicable; - air inlet system; - exhaust system; - fuel equipment; - control equipment; - electrical equipment; - additional auxiliary systems, including starting, lubrication, barring, compressor wash, pipework, drains and vents; - fire and gas protection; - cooling water equipment. Where applicable to the integrity of the gas turbine package, the interface and applicable design requirements are included for equipment, utilities and supplies that interface with the power generation package. The following equipment is excluded from the scope of supply, but references are included where required for interface or performance measurement: - generator and auxiliary systems, except the module control option; - steam turbine and auxiliary systems; - equipment external to the power generation package. Data sheets in Annex A of this International Standard are provided for defining requirements and exchanging information between the Purchaser and the Contractor. The Purchaser fills in the data sheets for the tender and forwards them to the Contractor. The Contractor responds by completing the applicable data sheets for their tender. Annex A identifies the different types of data sheets and how they are to be used. Where the Contractor does not comply with a selected requirement of this International Standard, this is detailed as an exception, referencing the applicable clause and describing the deviation and any alternatives available in a document listing all the exceptions taken. Where the text in this International Standard requests procedures and operating, maintenance and commissioning manual information or equipment that would require the disclosure/supply of proprietary information/equipment which the Contractor is not prepared to release, such exceptions are listed. Where this situation exists, the Contractor will be prepared to release appropriate personnel and equipment to undertake all the tasks that otherwise would be undertaken by the Purchaser.
