| İSGÜM / TS EN ISO 9612 Approach | In İSGÜM's laboratory authorization resources, the TS EN ISO 9612 task-based, job-based, and full-day measurement approach is used for personal noise exposure. Job analysis, appropriate measurement strategy, measurement, uncertainty evaluation, and reporting must be conducted together. |
|---|
| Personal Exposure Measurement | For comparison with occupational exposure limit values, personal noise exposure must be monitored from a point close to the worker's hearing zone. The Edge 8 supports shift- and task-based measurements with its shoulder-worn personal dosimeter design. |
|---|
| Four Independent Dosimeters | Edge 8 can run four independent dosimeter profiles simultaneously; threshold, exchange rate, and criterion level parameters can be independently configured according to corporate procedures or different assessment criteria. |
|---|
| ATEX / IECEx Hazardous Area | TSI's current technical datasheet for the Edge 8 specifies ATEX Directive 2014/34/EU and IECEx certifications. The instrument supports Ex ia IIC T4 Ga and Ex ia I Ma classifications. Prior to use, the field zone classification, gas group, temperature class, and current certification scope must be independently verified. |
|---|
| Measurement Data for ISO 9612 | RMS, dose, TWA, LAVG/LEQ, peak, maximum/minimum values, and time-history records can be used in personal exposure evaluation. 1/1 octave analysis provides additional data for evaluating the frequency composition of noise and noise control measures. |
|---|
| Calibration and Field Check | Pre- and post-measurement acoustic verification must be conducted using an appropriate calibrator and a valid field procedure. Manufacturer safety instructions and site procedures must also be observed for accessories and operations to be used in hazardous areas. |
|---|
| Raw Data and Recording | Edge 8 provides a logging capacity of up to 100 days with a 1-minute logging interval. Measurement data can be stored, analyzed, and reported via EdgeConnect and DMS. |
|---|
| Application in Turkey | Under the TS EN ISO 9612 method, instrument standard compliance alone is not sufficient. Together with calibration, microphone location, task durations, uncertainty calculation, and laboratory procedures; suitability with the facility's hazardous area classification must also be verified in ATEX/IECEx areas. |
