(Test Method)Standard Test Method for Determining Water Holding Capacity of Fiber Mulches for Hydraulic Planting
Standard Test Method for Determining Water Holding Capacity of Fiber Mulches for Hydraulic Planting
SIGNIFICANCE AND USE
5.1 The meaning of the test is related to the manufacturing and end use of the material, to determine characteristics of products. The water holding capacity of hydraulically applied mulches for hydraulic planting correlates directly with enhanced slurry and spray patterns by providing better soil/slurry binding ability and rate of seed germination.
SCOPE
1.1 This quantitative test method determines water holding capacity of fiber mulches, including wood, paper, and agriculturally derived and blended fiber mulches used for hydraulic planting.
1.2 The purpose of this test method is to provide a means of evaluating water holding capacity in fiber mulches. Product specimen is conditioned and weighed, saturated and re-weighed to determine water holding capacity. The water holding capacity is expressed as a percentage of increased weight after saturation. There are no known limitations to this test method. No range of concentrations/values have been determined. This test method is preferably performed in a laboratory.
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
