ISO 14509-1:2008(E) iv © ISO 2008 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14509-1 was prepared by Technical Committee ISO/TC 188, Small craft. This first edition of ISO 14509-1 cancels and replaces ISO 14509:2000, which has been technically revised. It also incorporates the Amendment ISO 14509:2000/Amd.1:2004. ISO 14509 consists of the following parts, under the general title Small craft — Airborne sound emitted by powered recreational craft: ⎯ Part 1: Pass-by measurement procedures ⎯ Part 2: Sound assessment using reference craft ⎯ Part 3: Sound assessment using calculation and measurement procedures

INTERNATIONAL STANDARD ISO 14509-1:2008(E) © ISO 2008 – All rights reserved 1Small craft — Airborne sound emitted by powered recreational craft — Part 1: Pass-by measurement procedures 1 Scope This part of ISO 14509 specifies the conditions for obtaining reproducible and comparable measurement results of the maximum sound pressure level of airborne sound generated during the passage of powered recreational craft of up to 24 m length of hull, including inboards, stern drives, personal watercraft (PWC) and outboard motors. It also specifies standard craft based type tests for stern drives with integral exhaust systems and for outboard motors. It also specifies the procedure to be followed if, in addition to the maximum sound pressure level, the determination of the sound exposure level is desired. NOTE For craft other than those specified above, ISO 2922 is applicable for sound emission measurements. The accuracy grade of the acoustical test procedures specified in this part of ISO 14509 is engineering grade (grade 2). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 8665, Small craft — Marine propulsion reciprocating internal combustion engines — Power measurements and declarations ISO 8666:2002, Small craft — Principal data ISO 10087, Small craft — Craft identification — Coding system IEC 60942, Electroacoustics — Sound calibrators IEC 61672-1, Electroacoustics — Sound level meters — Part 1: Specifications 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 type test for recreational craft type test measurement performed to prove that the sound of the craft in motion, or of the outboard motor when using a standard craft, or of the stern drive with integral exhaust system when using a standard craft, complies with sound specifications or prescribed limits NOTE See also definition of “acceptance test” in ISO 2922.

NOTE 2 See also definition of “monitoring test” in ISO 2922. 3.3 maximum A-frequency weighted sound pressure level with time weighting S for recreational craft maximum AS-weighted sound pressure level LpASmax maximum sound pressure level achieved from measurement of the passage of the craft under specified operating conditions measured with frequency weighting A and with time weighting S (slow) according to IEC 61672-1 NOTE It is expressed in decibels (dB). 3.4 A-weighted sound exposure EA,T integral of the square of the A-weighted sound pressure, p, over a stated time interval or event of duration T (starting at t1 and ending at t2) ()212A,AdtTtEptt=∫ (1) NOTE 1 Unit: pascal squared second, Pa2 s. NOTE 2 By practical limitations of the measuring instruments, p2 is always understood to denote the square of a frequency-weighted and frequency-band-limited sound pressure. The application of a specific frequency weighting as specified in IEC 61672-1 is indicated by an appropriate subscript, e.g. EA,1h denotes the A-weighted sound exposure over one hour. NOTE 3 When applied to a single event of impulsive or intermittent sound, the quantity is called “single event sound exposure” and the symbol E is used without subscript. NOTE 4 This definition applies only for the optional measurement of sound exposure levels according to Annex A.

NOTE 4 In this part of ISO 14509, the sound exposure level is to characterize the emission of the source and not the noise impact on people exposed to the sound. NOTE 5 This definition applies only for the optional measurement of sound exposure level according to Annex A. NOTE 6 Adapted from ISO/TR 25417:2007, 2.6. 3.6 background noise for recreational craft background noise noise from all sources other than the craft under test EXAMPLE Noise from waves splashing on the measuring craft or the shore, other craft or equipment, and wind effects. 3.7 stern-drive propulsion unit with the engine inboard and the transmission/drive located external to the hull 3.8 stern-drive with integral exhaust systems stern-drive where the exhaust gases are expelled through the transmission/drive 4 Symbols L′pASmax maximum AS-weighted sound pressure level during the passage, expressed in decibels (dB); L″pAS AS-weighted background sound pressure level, expressed in decibels (dB); LpASmax L′pASmax after applying background noise correction according to 8.3 and distance correction according to 9.2, expressed in decibels (dB); L′AE A-weighted sound exposure level during the passage, expressed in decibels (dB); L″AE A-weighted background sound exposure level, expressed in decibels (dB); LAE L′AE after applying background noise correction according to A.5 and distance correction according to A.6, expressed in decibels (dB). 5 Measurement quantity The quantity to be measured during the passage of the craft is the maximum AS-weighted sound pressure level, L′pASmax. From this quantity, the maximum AS-weighted sound pressure level, LpASmax, is determined by applying the background noise correction and distance correction, if applicable. 6 Measurement uncertainty The measurement procedure specified in the following clauses is affected by several parameters (e.g. measurement system uncertainty, environmental conditions, craft course uncertainty) that can lead to variation in the level recorded for a given craft. SIST EN ISO 14509-1:2018



ISO 14509-1:2008(E) 4 © ISO 2008 – All rights reserved In the absence of sufficient experimental data on the overall uncertainty, the uncertainty associated with this part of ISO 14509 has been evaluated by the procedure given in the Guide to the expression of uncertainty in measurement (GUM) (see Bibliography), where each individual source of uncertainty is identified and quantified based upon existing statistical data or engineering judgment. The individual sources of uncertainty identified, with their standard deviations, are given in Table 1. Table 1 — Standard deviation of reproducibility of individual sources of measurement
Individual sources of uncertainty Individual standard deviations of the maximum AS-weighted sound pressure level, LASmax dB Distance effects 0,3 Measuring equipment 1,0 Environmental conditions 1,5 Operator effects 0,2 Test site variations 1,0 These individual sources of uncertainty are grouped as follows. a) Run-to-run: the variations expected within a single test series. b) Day-to-day: the variations expected within the same test site, but over more than a single test series and including a) above. c) Site-to-site: the variation expected across different test sites and test personnel and including a) and b) above. The expanded uncertainty for the combined standard uncertainties for these three groups, for a coverage probability of 90 %, is given in Table 2. Table 2 — Variability for a coverage probability of 90 % Variability case Expanded uncertainty dB Run-to-run 0,3 Day-to-day 1,8 Site-to-site 2,1 NOTE In addition to the above uncertainties, a further uncertainty needs to be considered in the case of multi-engined craft. If the sound of a specific multi-engined craft is dominated by exhaust noise, the phasing of its engines, when running at nominally the same engine speed, can have a significant effect upon the vessel’s pass by noise. Extreme examples of maximum AS-weighted sound pressure levels of up to 6 dB of the variability have been recorded. The uncertainties considered in this part of ISO 14509 do not cover the uncertainties associated with the variation in the production process for a specific craft. SIST EN ISO 14509-1:2018



ISO 14509-1:2008(E) © ISO 2008 – All rights reserved 57 Measuring equipment 7.1 Equipment specifications The instrumentation system, including microphones and cables (which shall be used according to the manufacturer’s specifications), and including the windscreen recommended by the manufacturer and the overall electroacoustic performance of any additional measuring equipment, including for example a tape recorder and/or level recorder, shall meet the requirements for a class 1 instrument specified in IEC 61672-1. NOTE Sound level meters with “maximum hold” capabilities are preferred. When a tape recorder is used for the measurements, the dynamic range of the instrumentation shall be consistent with the measured signal. A wind speed anemometer which has an uncertainty of less than ± 10 % shall be used. An engine speed tachometer which has an uncertainty of less than ± 2 % shall be used. 7.2 Equipment calibration A class 1 sound calibrator which meets the requirements of IEC 60942 shall be used. The overall acoustic performance of the measurement equipment shall be checked with the sound calibrator according to the instructions of its manufacturer at the beginning and at the end of each series of measurements, at least every four hours during testing and at the beginning and end of each measurement day. At intervals of no longer than two years, the sound level meter shall undergo laboratory verification for compliance with IEC 61672-1. The date of the last verification of compliance with IEC 61672-1 shall be recorded. The sound calibrator used for calibration of the sound level meter shall undergo laboratory verification every year with traceability to a laboratory, using national standards. 8 Test site specifications and environmental conditions 8.1 Test site specifications Within 30 m around the craft under test and the microphone, there shall be no large surfaces (e.g. retaining walls, building façades, rocks, bridges) from which sound can be reflected back to the microphone. In the vicinity of the microphone, there shall be no obstacles which could disturb the sound field. Therefore, no person shall be between the microphone and the sound source, and any observers shall be in such a position that any influence on the meter reading is avoided. The area between the craft under test and the measurement microphone shall be open water and free from any sound absorbing or sound reflecting objects that can affect the measurement. At the test course, the depth of water shall be sufficient for normal operation of the craft. NOTE Shallow water can increase the reading of the pass-by sound pressure level. 8.2 Environmental conditions 8.2.1 The wind velocity in the test area during the pass-by shall not exceed 7 m/s. 8.2.2 Tests shall not be carried out in conditions of rain or other precipitation.

ISO 14509-1:2008(E) 6 © ISO 2008 – All rights reserved 8.2.3 The wave height in the test area during the pass-by shall not exceed H according to Equation (3) or 0,1 m, whichever is the greater. H = Lwl/50 (3) where Lwl is the length of the waterline according to ISO 8666. NOTE The sound of any wave impact (slamming) could lead to a considerable increase of the measured sound pressure level. 8.3 Background noise 8.3.1 General A measurement shall be invalid if changes in the background noise affect the applicable reading. 8.3.2 Type tests For type tests, the AS-weighted background sound pressure level, L″pAS, shall be at least 10 dB below the maximum AS-weighted sound pressure level, L′pASmax, obtained during the passage of the craft. 8.3.3 Monitoring tests For monitoring tests, the AS-weighted background sound pressure level, L″pAS, shall be at least 6 dB below the maximum AS-weighted sound pressure level, L′pASmax, obtained during the passage of the craft. The reading shall then be corrected as shown in Table 3.
