FOR IMMEDIATE RELEASE – ASTM UPDATES D7322
Date: February 7, 2024
Subject: ASTM Updates D7322, Standard Test Method for Determination of Erosion Control Product (ECP) Ability to Encourage Seed Germination and Plant Growth Under Bench-Scale Conditions
ASTM International recently announced the approved revision of ASTM D7322, Standard Test Method for Determination of Erosion Control Product (ECP) Ability to Encourage Seed Germination and Plant Growth Under Bench-Scale Conditions.
This standard is used widely throughout the sediment and erosion control industry. The standard should inform end users if a product is found to display adequate percent germination improvement or inhibit vegetative growth. As such, sections 10 and 11 of this standard were revised to instruct laboratories to calculate a percent germination improvement for an ECP and report a pass or fail grade for the product. To pass, the biomass produced by a product under standard test conditions shall be >100% when compared to the biomass produced from a control, or bare soil trial under standard test conditions. Users of this test method should be advised to immediately revise current specifications or requirements that were based on previous editions of the standard.
The Erosion Control Technology Council (ECTC ) is a leading industry organization home to top manufacturers of erosion and sediment control products, component suppliers, material distributors, and test laboratories. ECTC members are dedicated to advancing the knowledge, experience, and expertise of erosion and sediment control. The non-profit organization’s mission is to develop performance standards, uniform testing procedures, and guidance on the application and installation of hydraulic erosion control products (HECPs), rolled erosion control products (RECPs), and sediment retention fiber rolls (SRFRs). ECTC recently expanded their reach to other technologies as well and they promote the use of erosion and sediment control products through industry leadership and education in the hope of making a substantial contribution to the science of erosion control and environmental preservation.
