(Test Method)Standard Test Method for Determination of Particles Resulting from the Attrition of Granular Pesticides
Standard Test Method for Determination of Particles Resulting from the Attrition of Granular Pesticides
SIGNIFICANCE AND USE
5.1 This test method is designed specifically for granular pesticide formulations.
5.2 This test method helps provide information on health hazards likely to arise from exposures by the inhalation route. It can be of use in selecting dose levels for chronic studies and for establishing safety criteria for human exposure.
5.3 The amount of fines determined by this method is a measure of potential inhalation and respiration toxicity because the hazards of inhaled solid substances are influenced by physical factors such as particle size.
SCOPE
1.1 This test method is used to determine the amount and particle size distribution curve of particles with diameter 106 micrometers or smaller resulting from the attrition of granular pesticides.
1.2 The values stated in SI units are to be regarded as standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statement, see Section 8.

4.1 The initial weight of a test sample of granular pesticide is determined. The sample is then air jet sieved using 10106 micron
openings to remove the inherent fines. The fines-free granules are then combined with glass beads in a glass jar, the lid is placed
on the jar, and the jar is placed on a roller system with a drive bed capable of rotating the jar at a known rpm. After rolling for
a specified time period, the jar is removed from the rollers and the contents of the jar are poured through a sieve sized to remove
