Question 1 of 30

When assessing compressed air quality against the stringent particulate requirements of ISO 8573-1:2010 Class 1, what is the most appropriate method for verifying compliance with the specified particle count threshold of fewer than 0.5 million particles per cubic meter that are \\( \\ge 0.5 \\text{ } \\mu\\text{m}\\)?

Employing a calibrated laser particle counter capable of resolving particles down to \(0.5 \text{ } \mu\text{m}\) and accumulating counts over a representative volume of air.

Conducting a visual inspection of a sample of compressed air passed through a clean white filter paper to detect visible contaminants.

Utilizing a chilled mirror hygrometer to measure the dew point of the compressed air and infer particulate presence from condensation patterns.

Immersing a desiccant-filled tube in the compressed air stream and observing the rate of desiccant saturation as an indicator of airborne moisture and potential particulate load.
