All calibration documentation issued by Odin Metrology, Inc. contains all information required by ANSI/NCSL Z540, ISO Guide 25 and ISO 17025. Detailed worksheets with all data for "as recieved" condition and for "as final" are provided with all calibrations. Sound level meters are calibrated to the international standard for which they are designed. Older model sound level meters are generally tested to IEC 60651 (often abbreviated as IEC 651) or ANSI S1.4, which are, in essence, the same standard. Modern sound level meters are tested to IEC 61672. Most sound level meters have a clear marking on the backside indicating which standard they are designed for.

Larson Davis 812/820 (IEC 60651)	A report for a Larson Davis type 812 or 820 sound level meter consists of 9 pages of data including extensive toneburst testing as per IEC 60651. Other tests include differential level linearity, frequency responses for A and C frequency weighting, and test of overload detector functionality. View example 820 report in PDF format
Brüel & Kjær 2250/2270 (IEC 61672)	Reports for the Brüel & Kjær sound level analyzer type 2250, and variants 2250 Light and 2270, contain data for the SLM and the octave filters, if a license for Frequency Analysis is installed. For 2270, data is supplied (both SLM and filter data) for each of the two channels. The filter report includes data about linearity and band edge responses. With no special instructions, Odin Metrology will supply a limited filter report containing data for a single 1/1-octave filter. However, if requested, Odin Metrology is capable of supplying a "full" filter report containing a filter response for each of the 11 1/1-octave filters and each of the 33 1/3-octave filters, resulting in an 85-page report for a 2250 or a 2270 with 1 channel or a 115-page report for a 2270 with 2 channels.

Larson Davis LxT/831 (IEC 61672)	Reports for the Larson Davis sound level meter type 831 contain data for the SLM and the octave filters, if a license for installed. The filter report includes data about linearity and band edge responses. With no special instructions, Odin Metrology will supply a limited filter report containing data for a single 1/1-octave filter. However, if requested, Odin Metrology is capable of supplying a "full" filter report of 64 pages containing a filter response for each of the 12 1/1-octave filters and each of the 36 1/3-octave filters.

Brüel & Kjær 2133 analyzer	For Bruel & Kjaer filters incorporated into analyzers like the 2131, 3360, 2123, 2133, 2140, 2144 and for sound level meters 2236 and 2238, a complete filter analysis report is included at no charge as part of the regular calibration documentation. For instance, for the 2133 and 2144 each 1/3 and 1/1 octave filter from 20 Hz to 20 kHz is measured at 64 different test frequencies and compared to the tolerances as specified in ISO 1260, 1995 resulting in an 85 page Filter Analysis Report. View example page from 2133 filter report in PDF format (Note: actual analyzer filter report is 85 pages)
Brüel & Kjær 4191 condenser microphone	Microphone calibrations are documented with a three page certificate containing all necessary details. The third page contains 1/3 octave tabulations for the microphone's frequency response: actuator, pressure (if applicable), 90 degree incidence, free field and random. Upon request, the electronic data can be delivered to the customer in Microsoft Excel format for use in correcting data obtained, for example, from B&K PULSE system.

Brüel & Kjær 4383 single-axis accelerometer	Accelerometer calibrations are documented with a two or three page certificate. Pages one and two contain the calibration information as obtained by the Brüel & Kjær Transducer Calibration System Type 9610 and technical data about 9610. Page three shows an optional mounted resonance plot. View example single-axis accelerometer certificate in PDF format
Brüel & Kjær 4524B triaxial accelerometer	Triaxial accelerometer calibration is documented with a two-page certificate. containing the calibration information as obtained by the Brüel & Kjær transducer calibration system type 9610 and technical data about 9610.
