ASTM D7322/D7322M-16e1
(Test Method)Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Ability to Encourage Seed Germination and Plant Growth Under Bench-Scale Conditions
Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Ability to Encourage Seed Germination and Plant Growth Under Bench-Scale Conditions
SIGNIFICANCE AND USE
5.1 This test method evaluates the effect of an RECP on seed germination and initial plant growth in a controlled environment.
5.2 The results of this test can be used to compare RECPs and other erosion control materials to determine which are the most effective at encouraging the growth of vegetation.
SCOPE
1.1 This test method covers guidelines, requirements, and procedures for evaluating the effect of Rolled Erosion Control Products (RECPs) on seed germination and vegetation enhancement.
1.2 This test method will evaluate the effects of RECPs on seed germination in a controlled environment.
1.3 This test method utilizes bench-scale testing procedures and shall not be interpreted as indicative of field performance.
1.4 This test method is not intended to replace full-scale simulation or field testing in acquisition of performance values that are required in the design of erosion control measures utilizing RECPs.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.6 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.
