Analysis:

Weight measurement for respirable dusts

Method: IRSST - 48-1

Sampling protocol

Sampling device:
Sampling media required:

#IRSST	Description
902	Preweighed PVC filter, 37 mm, 5 µm

Parameters:
Flow rate: 1,7 (nylon) 2,75 (GS3) L/min
TWA sampling volume: 180 L
STEL sampling volume: -
Remarks: A cyclone is required for sampling. The cassette to be used is directly related to the cyclone used. The GS3 cyclone must be used with cassette 997.

Analytical protocol

Principle: Gravimetric measurement (Grav)
Precision (%): 4,0
Minimum reported value: 25 µg
Remarks: Additional information is available in Info-Labo 1991-03. The weight measurement method for dusts is by definition non-specific.
