Test procedure for coal-mine-dust-personal-sampler units
Technical Report
·
OSTI ID:7238007
The performance of coal-mine-dust-personal sampler units is specified by 30 CFR 74. Tests for filter resistance, rotameter calibration, flow against resistance capsule preweight, flow rate consistency, high and low charge rundown, and pulsation frequency are given. The tests are used as part of the determination for whether or not a unit is approved. It should be noted that simpler requirements may not have written test procedures and other procedures may be published separately. (GRA)
