    Revision of E726 - 01(2015) Standard Test Method for Particle Size Distribution of Granular Carriers and Granular Pesticides

    Rationale

    The method is being run slightly different. The practice is to tare all the screens first and then after shaking, weigh the screen and the product, and calculate the amount left on the screen by subtracting the tare weight. The current method requires extracting the material from the screen which could affect precision and accuracy. It is recommended to discuss this method and perhaps conduct a new round robin study to determine accuracy and precision.
