    1. Scope

    1.1 Rainfall simulators are used in the experimental process of erosion testing and performance testing of erosion control products. Quantification of the raindrop size is an important component of understanding the conditions applied to the test plot. This test method is used to determine raindrop size of simulated rainfall by using the flour pan method. It is intended for use with indoor or outside test plots as a measurement tool for determining the raindrop size produced by the facility with specific operating parameters (that is, raindrop emitter configuration, supply line pressure, and so forth). 1.2 Units--The values stated in SI units shall be regarded as the standard. The values stated in parentheses are provided for information only. 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.

    Rationale

    This practice is needed for determining simulated raindrop size at laboratories.

    The title and scope are in draft form and are under development within this ASTM Committee.
