# §1065.295. PM inertial balance for field-testing analysis.

- (a) **Application.** You may use an inertial balance to quantify net PM on a sample medium for field testing.
- (b) **Component requirements.** We recommend that you use a balance that meets the specifications in Table 1 of [§ 1065.205](/cfr/40/1065.205.md). Note that your balance-based system must meet the linearity verification in [§ 1065.307](/cfr/40/1065.307.md). If the balance uses an internal calibration process for routine spanning and linearity verifications, the process must be NIST-traceable.
- (c) **Loss correction.** You may use PM loss corrections to account for PM loss in the inertial balance, including the sample handling system.
- (d) **Deposition.** You may use electrostatic deposition to collect PM as long as its collection efficiency is at least 95%.
