(Test Method)Standard Test Method for Sampling Granular Carriers and Granular Pesticides
Standard Test Method for Sampling Granular Carriers and Granular Pesticides
SIGNIFICANCE AND USE
This procedure was designed principally for clay, corncob, nut shell, or sand granular carriers and granular pesticide products but need not be limited to these materials. There may be more appropriate sampling methods for other types of granular carriers and products.
SCOPE
1.1 This test method presents general procedures for sampling and sampling practice for granular carriers and granular pesticides.
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 statements see Section 5.
